*** This bug is a duplicate of bug 31699 *** If aplay never exits, it looks like some other application (esd?) has monopolised the oss emulation device (/dev/dsp). Please confirm by providing the output from ``lsof /dev/dsp* /dev/snd/*''.
Please kill whatever application is hogging /dev/dsp, then try the aplay tests again. Just an hour ago on irc (#ubuntu+1), I assisted someone in resolving an essentially identical issue by having the person execute the following in a Terminal then rebooting: $ echo "options snd-usb-audio index=-2" |sudo tee -a /etc/modprobe.d /alsa-base The above command forces any other ALSA driver to prioritise itself before the one for usb devices. You will still be able to select a[nother] default sound device. -- Cannot change default sound card https://launchpad.net/bugs/40864 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
