[Voyage-linux] USB DAC problems with Voyage 0.8 and new Voyage 0.8.5

[Bruno]

Hi Kim,

the format has been already commented, no result.

My impression is that there should be some issue in ALSA mixer, as I 
found on Google that the warning messages

cannot get ctl value: req = 0x83, wValue = 0x201, wIndex = 0xa004

are related to it. But I don't know how to check this....

Thanks again

Ciao
Bruno
