Once I had a similar problem with a different brand (realtek) of the
same chipset managed by the very same driver. I tried to change the
options as you did, but the perfect solution came only after a few
months of work upstream. Maybe, that your chipset is not fully supported
at the moment.
That said, the thread you started is off-topic here considering this is
a KDE/Debian mailing list. In fact, from your description of the issue
you got, probably it is alsa related (you told that the problem is the
same with kmix and alsamixer) and for this reason hardly you will get
any help for your problem here.
