That's what I have. This is a new machine I built about 2 weeks ago. So drivers should be up to date as long as nothing came out within the last 2 weeks.

I have another MKV video with an AC3 track with 3F2R/LFE as the channels and I hear the audio ok on that one as well. It looks like my issues at this point is the one MKV AC3 track with Stereo for the channels.

I'm guessing I can re-encode that and modify the audio track (I'll have to check into that and see if that's possible). But I would like to see if I can get this working so I won't run into this again in the future.

By the way... thanks for all your help so far Smile

I did find an issue with 2 channel ac3 files. multi-channel files would work OK.
this is corrected in version 341, released earlier today.

the 2 channel ac3 seems to be the issue here.

I was innitially testing on a ATI system and experienced the 2 channel problem. As i was preparing v341 for release, I switched to an Nvidia based system and 2 channel worked and I made the statement quoted above.

I have since returned to the ATI system for further testing and the issue still exists with 2 channel AC3 files. Multi-channel AC3 is not a problem. I have no solution at this time.

another update.

I've rebooted my ATI system and no longer have any issues with 2 channel AC3 inside of MKV files.
I will test on an Intel iGPU later today.

Thanks. I've rebooted my machine a number of times but 2 channel audio still doesn't work for me. Hopefully you'll be able to figure something out. Smile

Sorry to bug you about this again, but were you able to test on an intel iGPU to reproduce the problem? I updated to the latest versions you have available but I still can't hear audio on AC3 2-Channel MKV's.

Maybe some sort of option can be added to the LAV Config on the audio tab so that I can disable that on a 2-channel AC3 audio track, but have it enabled for all other AC3 audio tracks?

I have no issues with ac3 (2channel) audio in mkv being sent to the receiver as Dolby Digital.

To test, all i did was press [Reset All]
went to the audio tab and selected 'TruHD/DTS MA (digital Audio)
HERE IS the sample I used for testing.

I have no issues with that file either... but it's not 2-channel stereo. That file uses 3F2R/LFE for the channels.

sorry about that - I uploaded the wrong sample
I updated the download URL - please try again.

That video also contains 3F2R/LFE for the channels... not stereo Smile
