[Alsa-user] IEC958 Playback Source = AC-Link or A/D Converter ?

[Goga777 <go...@bk...>]

Hi

I have integrated VIA8237 sound card and I have the problem with Dolby Digital audio through Spdif (mono and stereo is
working through spdif) - I don't listen anything with DD with AC-Link and I listen the sound like ЭырррррррррррррррррррЭ
with A/D Converter/

My question - what should I choice in alsamixer - 'AC-Link' or 'A/D Converter' for spdif output ?
