I recently installed Ubuntu 16.04 on my desktop PC. My graphics Card is 780GTX, it is recognized and works. I updated to the 361 nvidia binaries driver. But the sound over HDMI doesnt work.
The device is connected and it is shown:
lspci | grep NVIDIA 01:00.0 VGA compatible controller: NVIDIA Corporation GK110 [GeForce GTX 780] (rev a1) 01:00.1 Audio device: NVIDIA Corporation GK110 HDMI Audio (rev a1)
But its not detected as an output device:
aplay -l Karte 0: PCH [HDA Intel PCH], Gerät 0: ALC887-VD Analog [ALC887-VD Analog] Sub-Geräte: 1/1 Sub-Gerät #0: subdevice #0
There is only the Mainboard analog output. I googled a lot. First I tried to disable the mainboard output in UEFI, but nothing changes. Then there are no devices listet in aplay -l. It seems that the device is there but ALSA doesnt recognize it.
I tried to update ALSA with: sudo apt-get install oem-audio-hda-daily-dkms
But the last lines are everytime:
Error configuring: oem-audio-hda-daily-dkms E: Sub-process /usr/bin/dpkg returned an error code (1)
I am not really a ubuntu GURU and hope you can help me. I hope, if the ALSA drivers are updated it will work, so I hope you can assist me to figure out the error.
Could it be that the daily build of the drivers is broken at the moment for 16.04???
