[nvidia] Audio does not auto-switch to HDMI after switching the connected HDMI TV on

[Norbert]

When I start the computer is the connected TV (HDMI) is off and the pulseaudio device stays on unplugged when I switch the TV on. If I switch the TV on before I start the computer, everything works fine.

alsa_output.pci-0000_01_00.1.hdmi-stereo

linux-image-14.0-15-generic

nvidia-graphics-drivers-384 (384.111-0ubuntu1) bionic

Regards,

Norbert

Hi,

I vaguely recall other people have reported this kind of bug before but can't find those other bugs. In the past it was an issue specific to the type of TV. So can you please also provide:

1. The make and model of TV.
2. Run this command to give us even more info: apport-collect 1745866

[Daniel van Vugt (vanvugt)]

Maybe bug 1707611?

[Norbert (asterix52)]

It is a server installation. I have only ssh connection to the system.
I tried to run "apport-collect 1745866" but I can't log in with the terminal browser.
Is there a way to make this via ssh?

I tried: apport-cli -f -p pulseaudio --save bug.apport

But it say no official ubuntu package.

[Norbert (asterix52)]

I found a workaround:

default.pa

load-module module-alsa-sink device=hw:1,7

[Daniel van Vugt (vanvugt)]

Yes the command should eventually print an https:// URL which you can copy into a web browser on a different machine.

I have Sound when I switch to tty1 (STRG+ALT+F1) and back to tty7.

[Daniel van Vugt (vanvugt)]

Interesting. That suggests the kernel is negotiating the audio at the same time as the display signal. It also suggests that the same negotiation does not occur if the TV is already connected when turned on.

I think we'll need to test with other non-nvidia GPUs/drivers to see if the problem persists, or if it's specific to the nvidia module.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Hi
i'm currently having a similar issue. Maybe its related.
It want audio output is switched to hdmi if the cable is plugged in.
module-switch-on-connect is loaded (its shown if i use pactl list) but nothing happens.
I also use nvidia proprietary driver. I noticed that NO udev event is generated if the cable is plugged in. I checked with udevadm monitor.

2nd issue, if i switch manually to hdmi and then unplug the cable the original setting is not restored correctly, there is no sound after that. i need to manually select the internal speaker / output profile again to make it work.
