My hardware is a laptptop made by uniwill.
The sound is the SIS chipset: SI7013
The modules that get loaded are
snd_intel8x0
snd_intel8x0m
snd_ac97_codec
snd_pcm
snd_page_alloc

/var/log/messages shows:
intel8x0_measure_ac97_clock: measured 50428 usecs (2426 samples)
intel8x0: clocking to 48000

I took a look at https://bugzilla.redhat.com/show_bug.cgi?id=616197.
It looks like  the solution is specifig to dell models. Not sure
what to put in my /etc/modprobe.d/snd_hda_intel.conf.
