Recently my Creative X-fi expresscard has stopped working properly. It may be an alsa problem but it may also be some sort of bus problem, and I thought I'd let you decide. I filed Ubuntu bug 462843, which describes it in detail, but basically here's what happens. Sound usually works when I start the computer. But when I close and re-open my application, sound has gone. At the same time, alsamixer shows the card properly. The settings are fine. Asoundconf shows that the card is still there and registered as the default. sudo modprobe snd-hda-codec sudo modprobe snd-hda-codec-ca0110 shows that either the modules are loaded correctly or are able to be re-loaded, but still no sound. I fix by removing and re-inserting the card, and then re-booting the computer. This is for incoming (recorded) sound. I haven't checked the outgoing sound. I have the current Ubuntu version of the drivers, and have not tinkered with them at all. I re-installed the whole system recently. I updated to Lucid hoping to get better updates but that did not help. Here's everything interesting from dmesg|tail.
