I see and in (Launchpad #174) there is another confirmation that everything
works, this time with an UX534FTC.

I also got a report from a user in the Red Hat bugzilla about this:

On an UX534F just these 2 commands are enough to make everything work:

hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC0D0 0x20 0x400 0x7774

I'm not entirely sure if using the other 2 commands you gave me
are actively causing problems there, or if they just are not
necessary. I've asked the reporter about this.

So it looks like some models need just:

hda-verb /dev/snd/hwC0D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC0D0 0x20 0x400 0x7774

While others need all 4 commands:

hda-verb /dev/snd/hwC1D0 0x20 0x500 0xf
hda-verb /dev/snd/hwC1D0 0x20 0x400 0x7774
hda-verb /dev/snd/hwC1D0 0x20 0x500 0x45
hda-verb /dev/snd/hwC1D0 0x20 0x400 0x5289

Kailang, is that enough to write a kernel patch for this? If not
what other info do you need ?

Regards,

Hans
