I can confirm this bug. I'm using a RolandED UA-30 external with no internal card. The card doesn't work at all in firefox or other software which assumes alsa's default, and I've only gotten it working in mplayer by specifying the card in ~/.mplayer/config.
Strongly suggest adding a panel to set the default card. # aplay -l **** List of PLAYBACK Hardware Devices **** card 1: REC [UA-30 (44100Hz, Analog REC)], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 # modprobe -r snd_usb_audio # modprobe snd_usb_audio # aplay -l **** List of PLAYBACK Hardware Devices **** card 1: REC [UA-30 (44100Hz, Analog REC)], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 Although I disagree with the poster above...the ID is not fixed. The USB card initially was assigned device ID 0 immediately after adding the card to the system about a month ago. I haven't changed kernels in that time, or updated anything that should affect it. The card originally would sometimes stop working, when reassign itself to device ID 1, and then after disconnecting it and reconnecting it, would show up as 0 again, sometimes after several attempts. Eventually it no longer would revert to ID 0 and now is stuck at ID 1, and has been for about two weeks. The system is seldom power-cycled, but was yesterday and stayed at 1. Previously it would appear randomly at 0 or 1 after power cycling. So no, it very clearly is not assigned in a fixed sense. It seems to change for no apparent reason, and I have no idea why. Setting the default device is a useful tool, obviously because it will allow me to use the device in a temporary manner, but the ID is very much subject to change, and I haven't been able to determine any cause for that. Any additional information which is required I would be happy to provide. -- alsa-base: USB sound card registers as card 1 (leaving _no_ card 0) https://bugs.launchpad.net/bugs/65936 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
