Hi,

 I'm trying to use a KingRex UC192 converter. Alsa recognizes it
automatically, the log message shows
input: KingRex technology co.,ltd KingRex UC-192 USB TO Spdif/I2S converter
as /devices/pci0000:00/0000:00:04.1/usb1/1-2/1-2:1.2/input/input8
generic-usb 0003:040D:3410.0004: input,hidraw0: USB HID v1.00 Device
[KingRex technology co.,ltd KingRex UC-192 USB TO Spdif/I2S converter] on
usb-0000:00:04.1-
2/input2

'lsusb' shows
Bus 001 Device 004: ID 040d:3410 VIA Technologies, Inc.

  iSerial                 0
  bNumConfigurations      1

When I try use it I get no sound and there's the error message
"ALSA clock.c:116: uac_clock_source_is_valid(): cannot get clock validity
for id 128"


I'm using alsa 1.0.24 with slackware 13.1 and a 2.6.33.4 kernel

Any idea on how to fix it ?



Thanks
