[pulseaudio-discuss] Assertion 'usec <= ((pa_usec_t) 1000000ULL)*60ULL*60ULL' , failed at pulsecore/rtpoll.c:516

[Timo Harmonen]

Hi,

Basic Jaunty ltsp setup, kernel is 2.6.28-13, alsa-base is
1.0.18.dfsg-1ubuntu8.

I will try that "tsched=0" tomorrow. So it should work also
with module-detect? I haven't dared to change PA start script,
it is the one used in Jaunty ltsp.

I already replaced that card with some still older card. Probably an
easier fix than starting to update the alsa drivers :).
