Package: pulseaudio Version: 1.1-1 Severity: wishlist Tags: patch Usertags: pca-communication
Hi there! While trying to get Empathy working on a chroot [1], I followed Steve McIntyre's advice at [2]. [1] <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=649744> [2] <http://blog.einval.com/2010/11/12> However, none of the two hints produced a working PulseAudio: first, starting from version 0.99.1-1 there is no more need to configure any asound.conf [3] and, second, mounting /var/lib/dbus/ on the chroot did not change anything (and FWIW I have never experienced a "connection refused" error). [3] <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=605479#18> The problem was that the default device discovery through udev [4] was not working in the chroot: ===== (sid-desktop)luca@gismo:~$ /usr/sbin/service udev status udevd is running. (sid-desktop)luca@gismo:~$ grep -e alsa- -e udev- /etc/pulse/default.pa ### use module-udev-detect -- see below -- for doing this automatically) #load-module module-alsa-sink #load-module module-alsa-source device=hw:1,0 .ifexists module-udev-detect.so load-module module-udev-detect (sid-desktop)luca@gismo:~$ pulseaudio -v 2>&1 | grep udev I: [pulseaudio] module-udev-detect.c: Found 0 cards. I: [pulseaudio] module.c: Loaded "module-udev-detect" (index: #4; argument: ""). (sid-desktop)luca@gismo:~$ ===== [4] <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=601751> This was caused by the fact that /run/udev was not mounted in the chroot, which FWIW has nothing to do with other udev problems [5].
