Hi Matthew,
did you try to use alsa-mixer ? It was not working when I was trying the

Hi Matt,

and has an

Hi Clemens,
I can confirm that I get the original error with a Babyface, and that
this patch appears to fix it beautifully.
At least, insofar as it is

Hi, here is short update:
I tested the device and I get sound.
However, there seems to be a problem with the alsamixer, which is
already indicated in the dmesg output given in my old message (see
below). It seems that in mixer.c, the function get_ctl_value_v2 aborts
with the error message

Hi,
thanks for the information. I just commented the following part of mixer.c

Hiya, came across your discussion when trying to make my Fireface UCX work
with USB in linux.
I did try removing that code, and recompiling, but nothing much happened.
Does it need any particular config option? I am running with a shaved
low-jitter config.
Peace Be With You.
There are no particular msgs. Just usb-device connected.
Peace Be With You.

Hi,
I found some discussions online
(http://www.xcore.com/forum/viewtopic.php?f=8t=1719) which suggest
that it might be useful to disable the mixer, though this post relates
to a different sound card/slightly different problem. But it would
also fit to the last sentence of your answer.
