- E3500 report cval->max more than it actually can handel, so if you
set 95% capture level it will be muted. 2. betwen cval->min and cval-max(real) is 2940 control units, but real are only 7. 3. we found only 7 real control units, with cval->res = 384, but alsa can't handel less than 10 controls, so make it more and set cval->res = 192.

Thanks for the patch. The added code looks almost good. But, it's better to put your code into another place, e.g. a bit later so that you don't insert it between the comment and the other code. Also, if you use switch(), you need break.
In your case, simply put a new if () block with a proper comment after that switch() block. It's not necessarily merged into a single switch. The compiler should be clever enough.
Also, try to keep the patch checkpatch.pl-clean. Run it once before submitting your patch.
Could you fix these and repost?
thanks,
Takashi

There is some thing wrong with this. After suspend and resume this quirk not working. Even replug the cam not help, only reloading of snd_usb_sound will do it work again.
But isn't it irrelevant with your patch?
