[alsa-devel] How to deal with snooping in firmware?

[Paul Menzel]

Dear ALSA folks,


with Ubuntu 13.04 and AMD Kabini boards, there are audio distortions,
which are not present under Microsoft Windows [1][2]. Disabling snooping
fixes this, which is in line with the information from an earlier
discussion [3].

As it works under Microsoft Windows, is this indeed a driver problem and
should be fixed there? Is it better to disabling snooping by default in
the firmware and let the driver enable it? What do you propose how to
fix this?


Thanks,

Paul
