Hi,
I have been using the optical SPDIF from my MSI Speedster A4R
motherboard successfully of some time. Unfortunately, I now want to get
a coaxial SPDIF output from the motherboard and there isn't a RCA jack
on the back on the board. Currently, I am just outputing analog stereo
sound.
>From searching on the internet it looks like it should be possible to
retask one of the 3.5mm jacks to output the SPDIF information but I
haven't been able to work out how to do this so far. If I could retask a
jack then I could use a 3.5mm to RCA cable to plug it in to my stereo
which I did years ago with the es1370 driver.
Currently I am loading the snd-hda-intel module with the 5stack-digout
option to get the optical SPDIF working. Is retasking the line-out jack
for digital output possible?
There is also a JAUD1 jack on the board which isn't in the manual. I
think this is a front audio panel connector and I don't think that I can
get SPDIF from this. Someone who knows more may be able to correct me
there though.
Some info:
