After upgrading from 13.04 to 13.10 Dell's Inspirion 17R subwoofer stoped working.

In Ubuntu 13.04 was workaround by adding in the file /etc/modprobe.d/alsa-base.conf next line:

options snd-hda-intel model=ref

This issue was discussed here: How to activate subwoofer in Inspiron 17r?

After update previous workarounds don't help and I get no sound from any speaker in this case.

Is there some other fix for the latest version?
