 Posted: Thu Jun 26, 2008 10:41 pm Post subject: Phonon and dmix |
 |
|
Hi
I'm wondering how to make phonon use settings in .asoundrc and playback trough properly set dmix, normal alsa apps use it very good but phonon is making problems.
Is there any way to dmix at the same time internet browser (firefox with aoss), juk and some other apps in the same time? In old kde and gnome it's working out of the box but I don't know what's the problem with KDE4 and phonon.
Could somebody give some tip or a resolution to this problem?
Thanks in advance |

I'm interested in that matter, too.
Since KDE4 my audio is effectively unusable since phonon takes over the sound hardware and thats it.

to be honest:
IMHO phonon is even more crap, see my post before.
before my upgrade to kde4 I could at least play more than 1 stream at a time. ...
Now with the same system( no alsa config changed !) phonon blocks audio device and thats it.

Why do you need aoss for firefox? Flash has supported alsa for quite some time now.
For alsa in general, I've found you have the least problems without trying to tweak anything and let alsa do it's own thing out of the box. Or is there a specific reason you need to have an .asoundrc? |

after some time spend on google I put together this .asoundrc which makes spdif working with dmix(and regarding to original author) and mic input.
| Code: |
pcm.!default {
type plug slave.pcm "mic"
}
# this is needed for the mic
pcm.card0 {
type hw card 0
}
# this enables the mic
pcm.mic {
type asym playback.pcm "dmixer" capture.pcm "card0"
}
# dmix output over spdif
pcm.dmixer {
type dmix
ipc_key 1024 # must be unique!
ipc_perm 0660 # sound for everybody (at least in your group)
slave {
pcm "hw:0,1"
channels 6
period_time 0
period_size 512
buffer_time 0
buffer_size 4096
}
bindings {
0 0 # map from 0 to 0
1 1 # map from 1 to 1
}
hint {
show on
description "Onboard Soundcard"
}
}
|
Here the important lines:
under pcm.dmixer the line pcm denotes the physical output device
the "hint" section makes your dmix entry USABLE for PHONON !!! (you can select it after restarting alsa)
With this .asoundrc I can use any sound-source at any type together with spdif output
