 Posted: Wed Feb 14, 2007 1:52 am Post subject: Virtual ALSA Mixer (for MythTV)? [SOLVED] |
 |
|
I'd like to have the ability to mute only MythTV, allowing other applications to remain playing. Is it is possible, maybe in asound.conf, to create a virtual pcm device, through which MythTV can play, which would have its own virtual mixer?
The asound.conf seems pretty flexible, but I've only seen examples of virtual devices for dmix and multichannel support. If not possible with ALSA, can anyone think of another way?
Thanks.

I've found the solution. For those who might be interested to do the same thing, you can use the 'softvol' ALSA plugin.
In /etc/asound.conf or ~/.asoundrc:
| Code: | pcm.mythtv {
type softvol
slave.pcm "dmix"
control {
name "MythTV"
card 0
}
} |
This sets up a virtual device called 'mythtv' and anything that's played through has its volume modified by the 'MythTV' control (in like alsamixer) before outputting to whatever slave device you specify (in my case 'dmix').
Then in mythfrontend, set your audio preferences like:

so you can control the volume from within MythTV itself.
Man I'm happy! |
