Thanks for reporting.

Could you try the latest snapshot below and check whether the problem
still exists and model=dell-m4-1 works?
    ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz

If the model option is still needed, I'll add the quirk entry.

Note that you should reboot after changing the model option for
STAC/IDT codec, just to be sure.  When a model option is specified,
the driver may override the BIOS setting.


thanks,
