Summary: System stops completely when playing audio
Description:
I have a Tascam US-428. Wehen I connect to the USB, the driver is loaded,
the USB-LED of the 428 lights up. When I try to play audio (e.g. with
aplay or XMMS), the computer immedeately stops working. All I can do is to
push the reset-button. No log-entrys, nothing.

Now I have updated the alsa-drivers, now at least the System doesn't hang
when I Play audio, but there is no output (can't hear anything). I would
assume the usual problem with muted outputs, but alsamixer doesn't find
any controls.
Another problem still exists: If the US-428 gets disconnected after its
drivers and firmware have been loaded, the keyboard is dead. I can use the
mouse normally, but if I try to do a shutdown, the system hangs again.
Version is 0.8.6, kernel is now 2.6.10-gentoo (without the kernel-built-in
alsa-modules).

both keyboard dead & hangup shutting down after switching us428 off happen
here also sometimes. I think it is ok when I unload the snd-usb-usx2y
module first. ( $/etc/init.d/alsasound stop)
To the silence problem:
There is no alsa-mixer interface yet.
Is us428control activ? Check by pressing "INPUT MONITOR".
If us428control is activ, put the "MASTER" slider to 9 NOT 10.
10 magically equals 0 after us428 having started. (Seams to be some
feedback omitting strategy.)
If this doesn't help: can you verify that audio is really being played by
watching some transport indicators?
Any difference when you set nrpacks=1 on modprobe snd-usb-usx2y?
$rmmod snd-usb-usx2y
$modprobe snd-usb-usx2y nrpacks=1
