Specifically, if I boot an older machine with NetBSD-9.1 with an uchi(4) USBĬhip in it, the uaudio driver works fine with the C-Media USB audio device. The problem appears to be specific to the uhid0 at uhidev0: input=1, output=0, feature=0 uhidev0 at uhub1 port 7 configuration 1 interface 3 audio1: slinear_le:5Hz, blk 2640 bytes (59.8ms) for recording uaudio0: Burr-Brown from TI (0x8bb) USB Audio CODEC (0x2902), rev 1.10/1.00, addr 4 uaudio0 at uhub1 port 7 configuration 1 interface 0 this oneĭemonstrates the same errors as the C-Media device. Tried playing audio with a different USB audio device. This appears to be a larger problem with USB audio as I just To: Re: kern/55856: uaudio gets device timeout on C-Media USB sound device Into different USB ports on the system, with the same result.
