Posted: Wed Sep 26, 2007 6:40 pm Post subject: AC97: not able to play two sound sources at once

Hi,

I am not able to play 2 sound sources at once. i use gnome 2.20 from gnome-experimental-overlay.

Basically I need Teamspeak and Tremulous-bin at once. Both should use my sound card. If I try it, I can use Teamspeak, but I don*T have any sound in tremulous. Only Tremulous works with sound, but not both.

May you help me. I don*t have any glue, I have used google for 2 weeks at least to get any solution. Thank you.

E.g. One Mplayer is playing my webradio

2nd:

there's something about this in alsa wiki

Quote:

For example under Debian/GNU Linux it is possible that you have installed ESD for /dev/dsp instead of ALSA, replace libesd0 with libesd-alsa0.

you seem to have esd running so maybe this is it

#http://gentoo-wiki.com/HOWTO_ALSA_sound_mixer_aka_dmix#pulseaudio

### Load audio drivers statically
#load-module module-alsa-sink
#load-module module-alsa-source device=hw:1,0
#load-module module-oss device="/dev/dsp" sink_name=output source_name=input
#load-module module-oss-mmap device="/dev/dsp" sink_name=output source_name=input
load-module module-null-sink
#load-module module-pipe-sink

### Automatically load driver modules depending on the hardware available
load-module module-hal-detect

### Alternatively use the static hardware detection module (for systems that
### lack HAL support
#load-module module-detect

### Load audio drivers automatically on access

#OSS
add-autoload-sink output module-oss device="/dev/dsp" sink_name=output source_name=input
add-autoload-source input module-oss device="/dev/dsp" sink_name=output source_name=input

#add-autoload-sink output module-oss-mmap device="/dev/dsp" sink_name=output source_name=input
#add-autoload-source input module-oss-mmap device="/dev/dsp" sink_name=output source_name=input

#ALSA
#the following line was added dmix
add-autoload-sink output module-alsa-sink sink_name=output device=dmix
add-autoload-source input module-alsa-source source_name=input

### Load several protocols
load-module module-esound-protocol-unix
load-module module-native-protocol-unix

#Load the CLI module, new
load-module module-cli

### Network access (may be configured with paprefs, so leave this commented
### here if you plan to use paprefs)
#load-module module-esound-protocol-tcp
#load-module module-native-protocol-tcp
#load-module module-zeroconf-publish

### Load the RTP reciever module (also configured via paprefs, see above)
#load-module module-rtp-recv

### Load the RTP sender module (also configured via paprefs, see above)
#load-module module-null-sink sink_name=rtp format=s16be channels=2 rate=44100 description="RTP Multicast Sink"
#load-module module-rtp-send source=rtp.monitor

### Automatically restore the volume of playback streams
load-module module-volume-restore

### Automatically move streams to the default sink if the sink they are
### connected to dies, similar for sources
load-module module-rescue-streams

### Make some devices default
set-default-sink output
set-default-source input

.nofail

### Load something to the sample cache
load-sample x11-bell /usr/share/sounds/gtk-events/activate.wav
#load-sample-dir-lazy /usr/share/sounds/*.wav

### Load X11 bell module
load-module module-x11-bell sample=x11-bell sink=output

### Publish connection data in the X11 root window
load-module module-x11-publish

### Load additional modules from GConf settings. This can be configured with the paprefs tool.
### Please keep in mind that the modules configured by paprefs might conflict with manually
### loaded modules.
load-module module-gconf
