Hi,
simoncn wroteIs the Cirrus Logic audio card supported on the current beta build? If not, is there any estimate for when this support will be available?
No it isn't.
The wolfson card is on the marked for more than one year and did not find its way into the mainline kernel.
For each update you have to compile your own kernel.
The Cirrus Logic card is the same only with support for RP + versions.
I do not believe in Cirrus Logic (wolfson) to get their card supported like others.
So for me it is not worth the work to integrate this card.
If someone would like to do this
here is the kernel source code. Instructions are also available
here.
