My sound seems to work for a while (pure ALSA at the moment, though I've had the same error using pulse too), then an event (mostly pause) seems to cause sound to stop working without a reboot. Here's the relevant information:
Bus 003 Device 002: ID 08bb:2706 Texas Instruments Japan
**** List of PLAYBACK Hardware Devices **** card 0: DAC [USB Audio DAC], device 0: USB Audio [USB Audio] Subdevices: 0/1 Subdevice #0: subdevice #0

From then on the device is not listed under aplay-l until the PC is restarted.
This has been driving me nuts for a while now, and I can't find a solution. Does anyone have any suggestions?
Thanks in advance for your help!
