Thanks a lot!
Playback now works again. Please commit!
uaudio0: Logitech Logitech USB Headset, rev 1.10/1.13, addr 2
uaudio0: audio rev 1.00
pcm0: <USB Audio> on uaudio0
Recording, as far as I remember never worked with the device.
With CURRENT+your patch, recording results in a kernel panic:
pcm0:record:0: record interrupt timeout, channel dead
pcm0:record:0: record interrupt timeout, channel dead
kernel trap 12 with interrupts disabled
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x48
fault code = supervisor read, page not present
instruction pointer = 0x8:0xffffffff802c7f57
stack pointer = 0x10:0xffffffffa5200b10
frame pointer = 0x10:0xffffffffa5200b50
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = resume, IOPL = 0
current process = 33 (irq22: pcm1)
^^^^^^^ huh?
Unfortunately kgdb does not like the dump.
