OK, then try to mute and raise all volumes to zero. If you see only "Master",
it's because of PulseAudio. Run, for example, "alsamixer -c0".

Does the pop noise happens even if all muted? If yes, at opening or closing
the device?

Also, be prepared to be capable to build alsa-driver modules manually in case
you test patches in future.

- Uninstall alsa-driver-kmp beforehand
# rpm -e alsa-driver-kmp-desktop

- Get alsa-driver-snapshot tarball from

ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz

- Extract tarball
% tar xvf alsa-driver-snapshot.tar.gz

- Run configure, make
% cd alsa-driver
% ./configure --with-debug=full --enable-dynamic-minors --with-moddir=updates
% make

- Install modules (as root)
% su
# make install-modules

- Restart ALSA
# rcalsasound restart
