Hi Lennart,<br><br>I've further compiled pulseaudio 0.9.10 and that version can open the same device (plughw:2) with the ALSA version in Fedora 10. Do you think if it is related to the new timing mechanism after 0.9.10?<br>

<br><br>Hi Lennart,<br><br>Thanks. I'll try.<br><br>On the other hand I suppose my sound card (EMU 0404 USB) only supports 24bit with MMAP interleaved.... Do you think it is the cause of the problem? However the same setup works fine when I was using Fedora 9.... but it doesn't work in Fedora 10 now. I also tried tsched=0 but no luck as well.<br>

</div>Hmm, it might be good idea to use ltrace to list the ALSA calls made.<br>
