Hi, I have a ltsp client with some cheap SoundBlaster card. PA fails to start, assertion fails, logs below. - Timo root at ltsp513:~# /usr/bin/pulseaudio --system --exit-idle-time=-1 --disable-shm --no-cpu-limit --resample-method= trivial --high-priority --log-target=stderr -L module-detect -L module-esound-protocol-tcp auth-anonymous=1 -L mo dule-native-protocol-tcp auth-anonymous=1 -L module-volume-restore -L module-rescue-streams -L module-native-prot ocol-unix auth-anonymous=1 -n --disallow-exit --disallow-module-loading -v -v -v D: main.c: Started as real root: yes, suid root: no I: core-util.c: Successfully gained nice level -11.
