Public bug reported: In Breezy, I was using the OSS driver cs4232, but it's gone in Dapper and the few drivers I tried didn't seem to work.
Th chipset is Crystal 4237B, Sound Blaster Pro-compatible. Inserting the ALSA drivers in isa/cs423x gives a 'no such device' error. ** Affects: Ubuntu Importance: Untriaged Status: Unconfirmed -- No sound on Latitude CP M233ST since upgrade to Dapper https://launchpad.net/bugs/53464 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
