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 :). - Timo Colin Guthrie wrote: > Hi Timo, > > 'Twas brillig, and Timo Harmonen at 10/08/09 10:35 did gyre and gimble: >> I have a ltsp client with some cheap SoundBlaster card.
