When this happens, the lowest frequencies of the played sound are very attenuated and what is still audible sounds unpleasantly metallic. Rebooting the machine immediately brings up the sound system in shape again, but it would be nice if they were a more sensible way to reset it! Here are the relevant lines of `dmesg`: pcm0: port 0xe100-0xe1ff irq 22 at device 17.5 on pci0 pcm0: [ITHREAD] pcm0: pcm0: Best regards, Michael
