Hello, Lee! You wrote on Thu, 6 Dec 2007 15:44:58 -0500: LR> How exactly are you testing it? What are the observed results? What LR> are the expected results? I've tested using multi-channel wav-file: aplay "chan-id.wav" Got result: ALSA lib pcm.c:2145:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.surround51 Also I did test with mplayer: mplayer -cache 8192 -framedrop -vo dxr3:prebuf:sync:norm=5 -vf expand=-1:-1:-1:-1:1:4/3:1,lavc=quality:25 -channels 6 -ao alsa "/mnt/sens/My Movies/Test AC3 v2.0.avi" Got: [AO_ALSA] alsa-lib: pcm.c:2145:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.surround51 [AO_ALSA] Playback open error: No such file or directory Could not open/initialize audio device -> no sound. Audio: no sound Creating .asoundrc file (as descrived on alsa wiki) doesn't help. Seems like alsa "thinks" what I have only 2 channels card but it's not correct. WBR, SeNS |
