Re: [Alsa-user] Audio codec channels as separate devices
Hello, I made the sound card's input and left channels as a separate device and run it by aplay -D myDevice test.wav arecord -D myDevice test.wav. So far so good but i can not see myDevice in alsamixer. Is there a solution for this?

Is there a solution for this? alsamixer will only be available for controls, which your soundcard has one. If you want to have a volume control for your virtual single-channel devices, you have to use another softvol plugin. - Mathias -- Open source business process management suite built on Java and Eclipse Turn processes into business applications with Bonita BPM Community Edition Quickly connect people, data, and systems into organized workflows Winner of BOSSIE, CODIE, OW2 and Gartner awards http://p.sf.net/sfu/Bonitasoft ___ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user

My .asoundrc is here:
pcm.snd_card {

card 1 # change to your cards number or name
}
pcm.gcleft {
type plug
slave {
pcm hw:1
channels 2
}
ttable.0.0 1

pcm.gcright {

ttable.0.1 1

pcm.nano {
type asym
playback.pcm gcleft
capture.pcm snd_card

pcm.nano2 {
type asym
playback.pcm gcright
capture.pcm snd_card
}
pcm.burak{
type plug
slave.pcm nano
}
pcm.burak2{
type plug
slave.pcm nano2
}
I want to make these devices appear in alsamixer instead of the card 1. Yes
this needs writing controller plugins. Any ideas?

alsamixer will only be available for controls, which your soundcard has
one.
If you want to have a volume control for your virtual single-channel
devices, you have to use another softvol plugin.

as said before, use softvol for that. Please note that this will then be
handled in software and therefore need CPU.
Just use something like this:
pcm.left {
type softvol
pcm.slave gcleft
...
}

Re: [Alsa-user] Audio codec channels as separate devices
I use it in a Desktop PC. What do you mean by need CPU?
I tried this and saw nothing an alsamixer.
Can i change the hardware device names in alsamixser using plugins?

Re: [Alsa-user] Audio codec channels as separate devices
Ok, i got the point about cpu usage. Can the soun device names be changed using plugins? I have searched the alsa plugins wiki page but couldn't get an answer for this. For example my device is named as hda_intel in alsamixer and i want to change it. Is it possible?

Re: [Alsa-user] Audio codec channels as separate devices
Hello,
please try using something like that. (un-tested). Playing to dev1 and dev2
should then create mono streams with are send to one of the dmixer channel.
Check http://www.alsa-project.org/main/index.php/Asoundrc to see what is going
on.
