"May be similar to bug #40116 - a well-known problem with the Thinkpad 600E, which also has this sound card. In this case it always incorrectly detects it as a cd4610."
We have no problem with CS4237B, but with CS4236B. I see no reason to think it is detected wrongly. The problem seems to be it try to load module CS4232, rather than module CS3236. I am not bright enough to know if bug #41990 is related. Close (for fix release) bug #18716, seems to have added a CS4236 module, but it was never automatically detected (or rather used). So this bug is to me like a request to really finish work done on #18716. Like original poster said, adding in /etc/modules: snd-cs4236 is enough for us to make it work. But we would like it to work out of the box. -- Crystal soundcard CS4236 module not loaded on startup https://launchpad.net/bugs/51965 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
