Audio muting and h/w acceleration issues

Postby JeffG » 30 Oct 2012 18:02

Two separate (I think) issues with 2.0.5 Twoflower, although both exist with all 2.xx versions (but not any 1.xx versions):

1. Muting audio in one VLC window mutes all audio from all Windows sources, including all other VLC windows. System is XP SP3, CCCP default options with older Santa Cruz audio card.

2. Same system, hardware acceleration is inoperative when opening files with .TS extension (does 'include TS' need to be checked in the Haali (or LAV etc) setup?. When same files are renamed to .MPG acceleration works perfectly.

Regarding 1, did you force the WaveOut audio output? This is not normal and I don't see how this can happen with the default DirectSound output.

Note however that VLC now saves the volume. So if you put it to zero and only then start another VLC instance, the new instance might start muted. That is very much by design. You need to disable volume saving in the preferences if you don't like that.

Remi, when you're good you're good. Yes 32-bit WAV was forced and I have no clue why. Thank you.

Just curious, the Santa Cruz driver has a specific option (enabled btw) for multiple WAV sources. Is this one-source limit in VLC?

It looks like a driver bug to me. VLC sets only its own stream volume, as far as I know.

Regarding 2. XP does not have hardware acceleration.
