You could try writing three asoundrc files, one for each card, then write a hotplug script which makes one of the asoundrc files the default when it detects one of the cards being connected/disconnected. The only problem with this is that I think all the ALSA configuration (reading and parsing the config files) is done by each and every program (presumably via alsa-lib.) This means that after the config file changes, you'll need to close and reopen any program using audio for the change to take effect.

[Alsa-user] Alsa on a laptop - how to dynamicly assign a card in asoundrc (depending on the cards existence)?
I have a laptop with an integrated snd-card (which doesn't this days), but I also have two external USB-sound-cards.. They are almost never connected at the same time, yet if one is connected it's a better choice then the internal sound card. I would like to automatically assign output to the usb card if available for some apps (not for all). In mplayer it's simple. In it's config file: ao=alsa:device=hw=default,alsa:device=hw=Xmod,alsa:device=default The first default is not an error - the manufacturer of one of my cards has called it "default"... But in audacious it's not so simple, I can't simply list the cards in a list..besides I need to assign the mixer as well. Is it possible to make an pcm/ctl device in asoundrc file that would redirect the output to the correct card/mixer depending on they existence? The algorithm should look more or less like: If "default" exist: pcm.redir -> plughw:default clt.redir -> default.Speaker Elsif Xmod exists: pcm.redir -> plughw:Xmod ctl.redir -> Xmod.PCM Else pcm.redir -> default (underneath dmixed&dsnooped internal sound card) ctl.redir -> card 0 fi Any idea how to write that in the asound file?

It's for the independent rear output or multi-channel output. When the multi-channel is enabled, the first DAC becomes unusable. (And, of course, the recording is disabled, too.)

Your descrption sounds like a CMIPCI. In that case, it's a bit hard to do that way because both outputs share the same DAC. So, the source must be exclusive.

Okay, I first expermiented with those: behaviour didn't change. Then I
tried "-autosync 30" which improved things a bit - movie was still
playing extremely slowly, but it at least *displayed* that A/V were in
sync. Well, no huge improvement...
Then I tried to insert a filter which always converts the sample rate to
48000 Hz (as this seems to work with one movie perfectly) - voila! Did
the trick!
I inserted (right after the default filter):
pcm.Filter_RateConvert {
type rate
slave {
pcm "Filter_Duplex"
rate 48000
}
}

This sounds a bit annoying - ALSA is supposed to be robust software (it
seems like it's been there forever) - is this part still work in progress?
Thanks all for your help and pointers!

Indeed, when I put those two lines to my ~/.asoundrc (my other coniguration resides in /etc/asound.conf) I see the exact same effect on videos which usually work. So it seems to be a format conversion problem?

Here is some output: IIRC mplayer uses the audio as a timing source, so if there are any issues with the audio it throws out the timing of the whole movie. I would suggest trying the A/V sync options to see if you can improve the behaviour at all (-framedrop, -hardframedrop, -mc) Personally I've found ALSA's plugins very difficult to get working reliably across a number of different programs, so the behaviour you describe doesn't surprise me at all.

[Alsa-user] random system crashes when outputting midi using snd-mpu401
I'm trying to get MIDI output (through the game port) to work, but my system locks up randomly when playing MIDI files using aplaymidi. Everything works fine for a few seconds to a few minutes, and then my system freezes and even the magic sysrq keys don't do anything, so I have to hit the reset button on my computer. My BIOS tells me that MIDI is port 300h, IRQ 10, so I run modprobe snd_mpu401 port=300h irq=10 to make MIDI work. My BIOS will let me change the port and IRQ, although I haven't tried it because I don't expect it to make any difference. Any ideas on what I can do to fix this, or to figure out what's causing it? I have ALSA 1.0.14 and ALSA lib 1.0.14a, with Slackware 12, kernel 2.6.21.5. I use the onboard sound card from my K7S5A motherboard, which uses the intel8x0 driver. Thanks.
