[alsa-devel] Trying to enable digital audio output - Intel HDA - AD1983

[Scott D'Vileskis]

Raymond--
Thank you very much!
hdajackretask from the alsa-tool-gui worked like a charm!
(Had to tunnel X over my SSH terminal, but that's no biggie)

If only I had time to write an XBMC plugin for hdajackretask :-)

Thanks Again!
