As a result, I'm unable to hear what people are speaking in movies because the speech is usually sent to the center speaker (correct me if i'm wrong. i'm new to all this 5.1 business). Anyway, adjusting the volume, muting/unmuting "Center" section, enabling/disabling "Mic As Center/LFE" doesn't have any effect on the center speaker. It stays silent. However, as I noted in the summary, the center speaker works with oss audio driver of xine/mplayer (using oss emulation). However, that mode is not perfect as the center speaker plays the role of left surround and vice versa. In addition, a right surround speaker stays always silent (i guess that's because the RS channel needs to be swapped with LFE; at least I got this impression by having a look at /usr/share/alsa/cards/NForce.conf:surround51). To sum up, my problem is that I can't get the center speaker (which, I guess, is channel 2 on my hardware) working with native alsa apps playing ac3/5.1 audio. ====================================================================== ---------------------------------------------------------------------- tiwai - 03-23-05 13:01 ---------------------------------------------------------------------- Try speaker-test in alsa-utils. For more debugging, the content of /etc/asound.state and /proc/asound/card0/codec97#0/* files are necessary. What is the crash of alsa-lib 1.0.9rc1? It's more important! (Note that you have to use alsa-driver 1.0.9rc1 with alsa-lib 1.0.9rc1.) ---------------------------------------------------------------------- modax - 03-25-05 00:37 ---------------------------------------------------------------------- ok. now I've upgraded to alsa-driver 1.0.9rc2 and alsa-lib 1.0.9rc2. I no longer experience mplayer/kaffeine crashes/stalls (which was, actually, kernel oopsing somewhere in snd_timer; I think it's not important anymore as rc2 fixed this). However, the different problem has arisen. -Dsurround51 (either with speaker-test or mplayer) outputs no sound at all or some jerky tones. kaffeine (xine) says "Audio output unavailable. Device is busy. ()", but this is not true! -Dfront works fine with any app (artsd/mplayer in 2ch mode/kaffeine in 2ch mode/aplay etc.) though. There's no /etc/asound.state on my system. However, I've found /var/lib/alsa/asound.state which I've targzipped together with the stuff from /proc/asound/card0/codec97#0/ and attached here.
