Sooooo, the soundon.user I had was this:

Code: Select all

sudo vmixctl attach /dev/oss/oss_hdaudio0/spdout0
sudo vmixctl rate /dev/oss/oss_hdaudio0/pcm0 192000
sudo vmixctl rate /dev/oss/oss_cmi878x0/pcm0 192000
sudo vmixctl rate /dev/dsp 192000
exit 0

I did that because I was trying to output to SPDIF specifically, but for some reason that never worked and SPDIF has never played anything other than a copy of pcm0. Hardware?

Well, I looked at dmesg and Vmix was complaining that device 5 was not compatible. I did 'ossinfo -v9' and device 5 was spdout0. So I disabled that line. Furthermore, I removed the CMI878x0 card in the process of troubleshooting this one. So I disabled that line. My new soundon.user is this:

Code: Select all

# Incompatible: sudo vmixctl attach /dev/oss/oss_hdaudio0/spdout0
sudo vmixctl rate /dev/oss/oss_hdaudio0/pcm0 192000
# sudo vmixctl rate /dev/oss/oss_cmi878x0/pcm0 192000
# vmixctl rate /dev/oss/usb16d0071a-1/pcm0 192000
sudo vmixctl rate /dev/dsp 192000
exit 0

I restarted the computer and it works! I don't know what changed to make the old file crash Vmix, someone should probably look into that.
