Audio problems .

Hi friends,
first of all, thank you very much for your work.

I'm experiencing this problem for the first time...
I made an encode with dual audio (DTS-HD) and also with two different subtitles.
With the player (MPC x64), If I change the audio 1 to audio 2, both audios  doesn't work anymore.
Even if I change the subtitles,  audios just don't work anymore.
But this, only when I use the PC monitor and speakers. If I use the TV as second monitor I don't have any problems.
Am I doing something wrong ?

Weird problem. Try with the internal audio renderer:
Options > Playback > Output

Does audio come back if you seek to a different position?

Look here when it happens:
Player Menu > Play > Filters > LAV Audio Decoder > Status tab
It shows green bars for the audio channels when it is decoding. It that continues then decoding is working, and problem is in audio driver.

At LAV Audio Decoder, the L and R bars are green... So..I'll have to update the audio driver. Thank you.

I only use LAV external filters. All internal filters are disabled.
In Playback > Output I have madVR.

Thank you very much for your answer.
I'll try with the audio driver and then I'll give feedback.

It was not the audio driver but I found the problem.
In Playback > Output > Audio Renderer I had to choose 3: Default DirectSound Device
instead of System Default.

Thank you very very much.

Thanks for the info. Will be helpful if others have similar issues.

Usually system default renderer also uses DirectSound, but in your case it apparently did not.
