Hello

I'm currently running bumblebee with the proprietary nvidia drivers on arch linux i can enable multimonitor support via the steps outlined in your multi monitor guide but hdmi audio support is not available, unless i switch the bios to discreate graphics only.

aplay -l displays the following: card 0: PCH [HDA Intel PCH], device 0: ALC98 Analog [ALC298 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0

Any ideas ?

Kind Regards

Ryan

Try the PCI rescan method from https://bugs.freedesktop.org/show_bug.cgi?id=75985

I have the same problem. echo 1 | sudo tee /sys/bus/pci/rescan also did not bring up the audio device. Something else I can try?

5.3 comes with a fix for the issue mentioned above https://github.com/torvalds/linux/commit/b516ea586d717472178e6ef1c152e85608b0ce32 In addition to it, I see there was other work related to HDA

So.. I don't know, just make sure to be running an updated driver, and try that?
