Setting hw.snd.pcm0.spdif_enabled to 1 does neither enable the
SPDIF, nor the COAX-digital port from my on-board soundcard. All
it does is disabling analog-out.
pcm0: <VIA VT8237> at io 0xbc00 irq 22 (5p/1r/0v channels duplex default)
pcm0: <VIA VT8237> port 0xbc00-0xbcff irq 22 at device 17.5 on pci0
pcm0: <Avance Logic ALC850 AC97 Codec>
pcm0: <VIA DXS Enabled: DXS 4 / SGD 1 / REC 1>
This is a known bug. Please refer to the snd_via8233(4) manual pages
for details explaination.
I'm closing this PR.
