Hi Bruno,
I used XMOS USB 2.0 development board and also got the same "cannot get ctl
value" warning like below:
root@voyage:~# dmesg|grep can
[ 7.972152] cannot get ctl value: req = 0x83, wValue = 0x201, wIndex = 0xa004
[ 7.973150] cannot get ctl value: req = 0x83, wValue = 0x200, wIndex = 0xa004
[ 7.974282] cannot get ctl value: req = 0x83, wValue = 0x201, wIndex = 0xb004
[ 7.977419] cannot get ctl value: req = 0x83, wValue = 0x200, wIndex = 0xb004
But my 0.8.5 MPD test bed works very well, see my "lsusb" and "cat
/proc/asound/cards" below:
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 20b1:0002 XMOS Ltd
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
0 [X20 ]: USB-Audio - XMOS USB Audio 2.0
XMOS XMOS USB Audio 2.0 at usb-0000:00:0f.5-1, high speed
Show me the output of "mpc play" then.
Regards,
Punky

I reinstalled Voyage MPD 0.8.5, configured everything and the USB DAC played correctly. BUT, after the first reboot,
didn't played anymore!!! I tried to reboot again, nothing. Tried to unplug and replug USB cable several times, nothing.

Hi Bruno,
Can you show the output of the following commands:
1. "lsusb"
2. "cat /proc/asound/cards"
You may try to unplug the USB cable and replug it to see if this is solved. My XMOS development board sometimes goes
to UAC1.0 mode and no sound. After replug it is change back to 2.0 mode and it works perfectly.

I have an USB DAC (Calyx) that works very fine with Voyage MPD 0.7.5.
When I installed Voyage MPD 0.8 I started to have problem. The DAC is recognized, but it does not sound. When
plugged to the USB port, appear these messages:
cannot get ctl value: req=0x83, wValue=0x201, wIndex=0Xa00, type=4
cannot get ctl value: req=0x83, wValue=0x200, wIndex=0Xa00, type=4
Same problem with Voyage MPD 0.8.5
Does someone have had the same problem? How to solve it?
Thanks
Bruno
