bonsoir,
sur la page
http://pulseaudio.org/wiki/PerfectSetup#PulseAudioDeviceChooser indiqué dans un autre fil, on trouve cette indication :
If you select the default ALSA device to be "pulse", you need to make sure that PA doesn't try to open the "default" device for its own audio output. If you previously were loading module-alsa-sink without special device argument this means you have to change it to the raw "hw:0" devices. Example:
load-module module-alsa-sink device=hw:0
load-module module-alsa-source device=hw:0
If you use HAL this is not necessary, because the raw ALSA device strings are used anyway.
The PulseAudio plugin for ALSA supports audio playback, audio capturing and supports the mixer.
Je ne vois pas trop à quoi cela correspond et donc ce qu'il faut faire...
Merci
Gérard
