I'd like to update this bug report with more info from Lucid. The sound mostly works, but still dies sometimes, and there are still problems with codec probing.

Suggest a bigger bdl_pos_adj. ** Tags added: apport-collected ** Description changed: Well, as title says, it's a Dell mini 10 with Karmic, fully updated. Sound works as expected for some time after startup, then dies with the following messages in syslog. ALSA hda_intel.c:647: spurious response 0x0:0x0, last cmd=0x87060 At this point, nothing but rebooting brings the sound back. I tried reloading alsa with <sudo alsa force-reload> or logging out and in. I've installed linux-backports-modules-alsa-2.6.31-19-generic 2.6.31-19.21, but that didn't solve it.
