[alsa-devel] Dell XPS One 2710 HDA Intel PCH - No S/PDIF Output - High Definition ALC275Q (ALC3260)

[marve]

Dear all,

Still haven't been able to get sound through S/PDIF. I know a little
about trouble shooting and today I checked if the receiver could receive
DTS from another TOSLINK S/PDIF enabled machine and yes, my receiver works!

The reason I am writing is that I'm out of options and wonder if this
might be a bug in a untested environment for ALSA, were I may help to
fix. Or maybe I'm just missing something.

Thanks for your help!
