[PATCH 1/3] ALSA: HDA: Fix master control for Cirrus Logic 421X

[PATCH 1/3] ALSA: HDA: Fix master control for Cirrus Logic 421X

[David Henningsson]

The control name "HP/Speakers" is non-standard, and since there is
only one DAC on this chip there is no need for a virtual master
anyway.

[PATCH 2/3] ALSA: HDA: Fix automute for Cirrus Logic 421x

[David Henningsson]

There was a bug in the automute logic causing speakers not to
mute when headphones were plugged in.

[PATCH 3/3] ALSA: HDA: Add support for Cirrus Logic 4213

[David Henningsson]

The CS4213 chip is similar to the CS4210, but it does not have
SPDIF capabilities. Also, it has fewer pins, and the vendor specific
nid is different. With this patch, we have working inputs and outputs
(and automute/autoswitch). However, we don't know anything about
the vendor specific processing coefficients, so we don't read or write
to that node in this patch.

Thanks, applied all three patches.

BTW, do you have alsa-info.sh outputs of these codecs?
I thought CS4210 has multiple DACs, but I have no data here so far.


thanks,
