I’ve got a Dell U3014 and I’m using the line-out on the monitor to drive my speakers. Up to 346.35, the audio would work fine before and after the monitor was asleep. With 346.47, after waking up, there’s no sound. The audio device is still present, and I can select it, but I don’t hear anything. I have to turn the monitor off and on again before the sound works.
I’m guessing this is related to:
Fixed a bug that caused DisplayPort audio to stop working after monitors are hotplugged.
I appreciate hotplug working better, but I put the monitor to sleep a lot more :-)
philipl, What was the earlier driver version work for you for DP audio issue? Please reproduce the issue and provide nvidia-bug-report by running nvidia-bug-report.sh script as root user. The nvidia-bug-report.sh will collect information about your system and create the file ‘nvidia-bug-report.log.gz’ in the current directory.
Sorry for delay. have updated bug with this latest info. We are still investigating this issue. It would good if you can share nvida bug report when issue hit. I
