The obvious solution when a video file refuses to play on a device is to convert the file into a format that is supported by the device. However, in this case, re-encoding the video file into another format is not necessary. This is because the TV is incompatible with only the audio stream, and re-encoding the video stream will not only be a waste of time but will also result in video quality that is worse than the original since all video conversions are lossy. What we need to do is convert the audio stream while keeping the video stream intact. This we can do with a software called Avidemux.
The name “Avidemux” is a misnomer. Although originally developed to handle only AVI files, Avidemux can today demux and mux all kinds of video containers including MKV and MP4.
Open Avidemux and then load the video file whose audio codec the TV doesn’t support from the File menu.
On the left hand side, under Video Output choose the Copy option. This should already be selected by default. Under Audio Output, choose AC-3 (lav). You can also choose AAC, but AC-3 is recommended for maximum compatibility.
Under Output format, choose either MKV muxer or AVI muxer or MP4 muxer depending on whether the original file was MKV or AVI or MP4. But you can choose any video container, it doesn’t matter as long as the TV supports it.
Now click the save button and that’s it. Encoding takes about 2 minutes per GB of file on an Intel Sandy Bridge machine which is several times less than it would take if the video was encoded. Best of all, you don’t lose the video quality.

thank you so much. My DVD player does not support MKV and I think i can now play any mkv file using this software. I use converter but it takes 1-2 hours to convert file.
ReplyDeleteIf your dvd player does not support mkv then u will have to change the container from mkv to mp4 which most commonly used and compatible. You can do that without having to re-encode the video but the codec will remain same. You can do this with x media recode. Load the video. Under output format select mp4. Under video tab select copy instead of convert. do the same for audio tab and encode the movie. it will only take couple of minutes.
DeleteNo. If your DVD player doesn't support MKV, then you cannot use this method to make MKV files playable. This method is only for converting unsupported audio codecs in an MKV file to a supporting one.
ReplyDeleteYou will have to convert the MKV file to a format that is supported by your DVD player.
oh sad to know this. :( . But thank you very much Kaushik for the information. I will wait for your post for any other method to play unsupported file on dvd player, other then converting.
ReplyDeleteI am nowise and learning a lot from your site. thanks again.
I would reccomend "PopCorn MKV AudioConverter"

I`ve been using since I`ve bought an LG 3D TV. It also doesn`t decode dts.
It`s fast and reliable.
I reccomend
Dear Kaushik, Thank you for your email and above, i do have the problem of " Unsupported Audio" on my LG LCD TV.. I downloaded the above software, open the MKV file and followed your instructions of choosing Copy for Video, AC3(Avi) for Sound and MKV muxer then clicked Save, the file converted came out as a FILE and not a video.. When i save it on USB and put in TV, the TV cannot see it in movies selection, where did i go wrong?
ReplyDeletehi Kaushik, i tried it again and this time on saving the file i saved it with .avi extension. The file output came out as AVI file and did not even play on the computer..
ReplyDeleteNow with AC3 audio my LG TV writes that the file is invalid, and it does not open it...
ReplyDeleteTo all those who are having problems with LG TVs, I'm sorry that I'm not able to help you because I don't have an LG TV to test it myself. When using the Avidemux, please try different audio/video formats and see if it fixes the problem.
ReplyDeletevery helpful thanks
ReplyDeleteThank you very much
ReplyDeleteHey Kaushik Patowary, I sincerely thank you for your this post. Actually I was a victim.
ReplyDeleteI have LG 47" LED TV purchased this year 2014. During purchasing TV I had checked thoroughly by playing a verity of files formats like MKV, AVI, DAT, MPEG, MP4, MP3 etc. and found all video files were compatible and playing both Video & Audio.
But today I got a Blu Ray Movie (Zindagi na milegi dobara 10GB). When I insert the USB disk to my TV and stated playing this movie (MKV) I found a message Unsupported Audio. Video was awesome but no audio.
Then I Google this problem I found your post. It works. Now I am enjoying this fantastic movie. Thanks you so much yar.
I find the other converter named Faasoft Video Converter also can do this task. And it is easier to use.
ReplyDeleteHappy with it.
Fast ! Its super fast i love it. Nov its copying to usb i hope it works !
ReplyDeleteDoesn't matter what I do, the file keeps come out as a Windows Shell Common Dll file. One time last week I got the file to actually come out as a video.Tried mp4, mkv, avi....doesn't matter
ReplyDeleteits awesome !! thanks a ton
ReplyDeleteHi Kaushik, I have a micromax LED tv , most of the MKV format videos does not play Audio, so i tried the above method provided by you, but when i try to convert the Audio it is asking me to save it as a new file .... after saving it as a new file i am not able to select the new file as audio in TV or else i cant play that audio file separately in the comp .... please let me know how to fix the issue .
ReplyDeleteI'm not able to follow you clearly. Are you saying the software saves the audio as a separate audio file? Or are you saying the new file (video with audio) is unplayable by both the TV and PC?
Deletehii kaushik,I am also facing the same problem,I can here the sound on my laptop but unable to here any sound on my Micromax LED tv so I followed the same procedure as you have mentioned above but when I try to convert the Audio it is asking me to save it as a new file.After saving it as a new file still I am unable to here the audio on my tv.Could you please help on this issue
Deletehey kaushik i jst converted my file..nd the software itself choose to destination to save the file and i was not accepting my custom location..secondly.. after saving i could not find my files ...even though the were showing saved when i clicked save button to save ..it showed that those files were already there ..?? thirdly can u please tell me how to check in which format the file currently is ??
ReplyDeletehello, pls can sumone tell me which audio nd video format does JVC tv support?
ReplyDeleteHey Kaushik I followed all your instructions but i still cant hear the audio on my Micromax led 50inch tv.
ReplyDeletedid the whole process file size got less.. but other than that nothing..still cant hear.
What should i do?
Bro a good rule of thumb is to experiment with different types of formats.. Try converting the video to mp4
DeleteHello. U need to put aac(lav) for audio. Ac-3 does not play on micromax TV. Then save it. With different file name so that u won't get confused.
DeleteSubtitles are lostt,, I need those subtitles...
ReplyDeleteplease if you coulld help...
Hi Kaushik .. Thanks , now the sound is normal on my led tv. But the subtitle cannot shown.. Please help
ReplyDeleteHi, I have done everything you said to. But now its coming up video not supported. It was just audio but now its both. Any Idea on what else I have to change?
ReplyDeletei've tried ur suggestions for mkv audio, but there is no change.
ReplyDeleteAccording to my experience, the Samsung TV may refuse to play some of these MKV files with an unhelpful audio codec error message displaying right on your screen. In fact, MKV is just a container format, holding video, audio, image or subtitle files in it. The video and audio files in different MKV files can be encoded with different codecs. For example, an MKV file with DTS audio can't be rendered on Samsung TV. To fix the problem, you need to convert MKV to a fully compatible format with Samsung TV. So does the AVI videos.
ReplyDeleteTo solve this issue, we may use iDealshare VideoGo to convert MKV and AVI to Samsung TV more supported video format.
it worked fine for me, I had audio problem with mp4 files and it solved now. Thanks
ReplyDeleteNothing happens when I press configure. Please help
ReplyDeleteWorks great for my LG TV. Many thanks!!!!
ReplyDeleteThanks Kaushik. Even though it didn't worked straight away, your steps and software you mentioned (Avidemux) helped to solve audio problem on Micromax TV with my little observation. Checked other videos which are played with audio on Micromax TV. AC3 (lav) with MKV MUX didn't worked for me. Then I selected AAC (lav) with MKV MUX and it worked. It was dual audio (Telugu+Hindi). Telugu played but not Hindi but thats enough for my family to watch.
ReplyDeleteThis program is great!!! I was able to convert a DTS sound format movie to an AAC format which let me watched the movie i downloaded to my LG TV!! Thanks alot :)
ReplyDeletem downloading now .. i"ll tell you later reviews.. hope it will work
ReplyDeleteTHANK YOU SO MUCH IT WORKS FANTASTIC!!!

DeleteI followed you instructions and all worked just fine. Thanks man.
ReplyDeleteDimitris from Greece
I've followed the instructions but can't find the SAVE button that is mentioned in the last step. Can someone tell me what I need to click after setting the Output Format please? It's probably staring me in the face - BUT!!!
ReplyDeleteThanks
Barry
The floppy disk icon in the toolbar is the save button.
Deletewhich audio formate supported in LG LCD tv right now.
ReplyDeleteThank you! Solved my playback issue and my family are now watching their movie :-)
ReplyDeleteGreat, this works. Convert into MP4 and you will have no issue
ReplyDeleteI downloaded this software and made changes accordingly as mentioned but still there is no audio while playing that video at my Videocon LED, please help
ReplyDeleteThank god for people like you taking the time to explain, in simple detail, how to deal with problems like this.. To all those above who have commented, Kaushik can't outline every single different file output for every type of TV model you, come on, do your research and find what audio your TV can handle
ReplyDeleteAvidemux works great. Many thanks.
ReplyDeleteThank you :)
ReplyDeleteworks a treat - cheers
ReplyDeleteis There any similar software for .VOB format conversion..Im facing similar issue when i play .vob file using a Thumb drive on 32 inch VU LED television.
ReplyDeleteVOB files are not meant to be played directly from a USB drive, because they contain additional information that the TV will not understand. It's better to convert the entire DVD (not the standalone VOB file) into a compatible format. In other words, rip the DVD.
DeleteHi, I did as instructed, and since the audio code change to AC3, the file size is reduced from 21Gb to 19Gb and the overall frame rate reduced from 20+bits to 16+ bits.
ReplyDeleteDoes that mean the audio format have different size too? I'm noob when it come to tech :(
I have Micromax LED HD 32 inch who does not support MKV video file, no audio. I tried to add audio through avidemux. On saving file, it shows *Muxer can not open*. Please solve my problem
ReplyDeleteFind subtitles for your movie (www.subscene.com), put it in the same folder as the movie, copy the exact name of the video file and paste it as name for the subtitles. "example - copy Pacific.Rim.2010.1080p.x264.Yify so that the only difference between subtitles and video file is the Mkv and Srt in the end.
ReplyDeleteGood luck.
Thanks
ReplyDeleteHi,
ReplyDeletei recently by panasonic 32c460DX model LED i m not able to play any dual audio movie, can u suggest me any other brand which can supprt all dual audia movie and formates, which wud be cheaper in 32 or 40 inch, because panasonic is waste for me now..
It really helped a lot to view mkv movies in Vu tv. Thanks a lot man.
ReplyDeleteKaushik is it confirm that micromax led tv support sac and ac3
ReplyDeleteDon't know about Micromax. The best way to find out is take a bunch of files of different format on a USB drive to the store and try to play them on the TV. Buy the TV that supports the most formats. I did the same and discovered Samsung supports the most format. LG, Sony, Panasonic are all behind.
DeleteMicromax supports aac(lav) not ac3,
DeletePls help... After I saved it.. It came out as a file format.. How can i convert it to video..im using Sony Bravia thank you so much.
ReplyDeleteAfter I followed all the instructions I saved it... File format how can I convert it to video many thanks.
