And there is a problem in CS46xx.conf file, i need to remove the hook on the rear pcm to permit multiple surround40 subdevices to be opened. ====================================================================== ---------------------------------------------------------------------- darkbrain - 02-06-06 10:46 ---------------------------------------------------------------------- Well i'm not an alsa driver guru, i think that simply we have 2 channels pcm 1 front and 1 rear and surround40 should be only an asound.conf "tweak" that merge them together to virtualize 1 surround40 channel. 3 channels are probably supported by cards that supports 5+1 channels and it's not my case. Hmm if i'm correct there is a problem only on the rear pcm, i'll test it. Any way by user side it works i can see a dvd with 4 channels and i tested it very well :) ---------------------------------------------------------------------- darkbrain - 02-06-06 18:37 ---------------------------------------------------------------------- I'm beginning to think that is not a memory leak problem or similar but a syncing one. Infact if i use a ruote device type such as: pcm.quad { type route slave.pcm "surround40:0" slave.channels 4 ttable.0.0 1 ttable.1.1 1 ttable.0.2 1 ttable.1.3 1 } ctl.quad { type hw; card 0; } and i play an mp3 throught quad, it results out of sync. Does pcm type multi, used for surround40, trying to sync 2 device?
