You missunderstood me, I want to use one player to play regular mp3's
and be able to hear it on both front and rear speakers. Even if I
could sync that thing above it would be a very ugly solution to my
problem.
Så, aplay some-2ch.wav works fine, except for the fact that rear
volume is initialized to 0. I can get some other routing channels
with a swich so rear volume isn't used, but then rear and front volume
aren't independent (se my first mail for details) :/ .
ok, then you need something similar like below:
pcm.dup4ch {
type hooks
slave.pcm {
type hw
card 0
device 0
}
hooks.0 {
type ctl_elems
hook_args [
{
name Rear Path
preserve true
value true
}
{
name PCM Reverb Playback Volume
index { @func private_pcm_subdevice }
preserve true
value 127
}
]
}
}
then run aplay -Ddup4ch some-2ch.wav

I've tryed playing some samples with aplay combined with -D parameter, e.g. aplay -Dfront foo.wav. However, what I want is to play a sample on both front and rear speakers, but control the sound level independently, so what remains is the surround40-pcm. When I try this (-Dsurround40) I get the following message: aplay: set_params:837: Channels count non available did you play a 4-channel sample file? I've tried reading documentation in alsa-driver source-tree, but it is sparse. No documentation on the homepage that I found covers what I am having problems with. :/ Any suggestions to where I should look? Mostly, it should cover pcm:s, this routing stuff and such. it's not the scope of the driver but the library. you might find some useful info in ALSA wiki page...

[Alsa-devel] problems with the mixer (fwd)
Hi! I didn't get any answer on alsa-user list so I try here. I have a Hoontech NX card with outputs for front and rear speakers. Volume settings for these I would like to set independently of each other, and this worked just fine while I was running ALSA 0.5.x. However, a couple of days ago I upgraded to ALSA 1.0.3. Now, there are two possibilities for controling volume settings on speakers, one with Sigmatel 4-speaker stereo off and another with this switch turned on. The second posibility (4-s s on), has following setup: - Master controls front speakers - PCM controls both front and rear speakers Sigmatel 4-speaker stereo off is almost what I want: - Master, PCM, PCM Front control front speakers - Surrownd, PCM Reverb control rear speakers However, PCM Front and PCM Reverb are set to 100% resp. 0% each time /dev/dsp is opened. This works perfectly for front speakers since they can be controled with Master or PCM controls, but rear speakers are muted each time a new song starts. Is this a bug? (I hope it is.) Is it a known bug, or is it some kind of feature I can hope to be able to go around in future release of trident driver?

[Alsa-devel] Problems with Extigy mixer settings.
Hi
I have been having som problems with mixer settings on my Sound Blaster
Extigy.
I am using the alsa from the linux 2.6.3 kernel. White alsa's usbaudio.
When starting it wood fail. When i set #define IGNORE_CTL_ERROR in
usbmixer.c it wood load but when alsamixer came to the settings for the
digital In mixer port it wood start printing errors to the console.
This patch fixes it by disabling the mixer channel which gave the
problems.
