I've seen that. But I did not seen anything about using a specific output of the card. as I only have one detected device, how can I set HDMI as default output? (or: how can I see my graphic card as a audio device too?) Is it that 'bindings' keyword, that's not explained on the wiki? 2010/12/3 Cédric Girard

You can control Alsa routing with the asoundrc [1] config file.

What does "cat /proc/asound/modules" give you? If it lists two different modules, maybe the driver you don't want is loading before the good one, causing alsa to pick the bad one as the primary. In which case you might just be able to fix that by placing the following in /etc/modprobe.d/modprobe.conf: "options module_name_here index=-2" which should make the bad module load after the good one. That happened on my system, and this fix worked perfectly for me. -- Andy On Thu, Dec 2, 2010 at 5:45 PM, Samuel Martín Moro wrote:

I just noticed: I've two pluseaudio items in the startup applications list (from gnome) first one doing 'start-pulseaudio-x11' and the other one: 'start-pulseaudio-kde' What's that? Might it be related? On Fri, Dec 3, 2010 at 9:12 AM, Samuel Martín Moro wrote:

I don't know the .asoundrc syntax but as far as I can tell you should tell your programs to use a dmix device instead of hw:something. dmix means software mixing while hw:something means the program uses the device exclusively.

If that doesn't work you could try PA.

Good luck.

I have now the following: pcm.card0 { type plug slave.pcm "dmix" hint { show on description "My dmix output" } } ctl.mixer0 { type hw card 0 } I also tried replacing slave.pcm "dmix" of card0 by "dmixer", defining the following: pcm.dmixer { type dmix ipc_key 2048 slave { pcm "hw:0,1" period_time 0 period_size 1024 buffer_size 4096 rate 48000 } bindings { 0 0 1 1 } } None of them fixed the problem. And I'm still not sure I'm calling the good output (the second test uses hw0,1, the first one does not specify it) But there's nothing coming out of my TV anymore. Also, when trying to open a file with alsaplayer, if vlc or banshee are already playing something, that error pops out: ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave snd_pcm_open: Device or resource busy (plug:dmix) [...] NOTE: THIS IS THE NULL PLUGIN. YOU WILL NOT HEAR SOUND!! I don't understand. As far as I remember, I was always able to play a game while watching a video and/or playing music.

lsof /dev/snd/*

this command will tell you what program has the sound card open.

I read to the pulseaudio wiki page, and tried to "finish" installing it (as I already may have start, if gnome's already lauching it... I just don't remember why/how/when I'ld have done that...) I installed - pulseaudio-alsa (why would I've installed pulseaudio without pulseaudio-alsa?!) - lib32-alsa-plugins (web browser sound does not work without it) - lib32-pulse and some gnome modules (gnome-media-....?-pulse, can't find them back in the history, but I had to uninstall their equivalents without pulse) then, I rmmod and blacklisted snd_pcm_oss, modified libao.conf to use pulseaudio /etc/asound.conf has been replaced (understand: move it, or the related package won't install), ... nothing special, just following the wiki page. And now, I can play quakelive/watch a flash video while listening to music, using vlc or banshee. Everything's back to normal. Except pulse is correctly installed. And, last but not least: TV and motherboard output the same thing, so I can choose to plug my jack to the TV or to the computer (while before, only vlc outputed on the TV). So, thanks for your help!
