Debian 9 doesn't change automatically audio device

vra · 04-01-2020, 05:37 AM

Hi all, how are you?. I have debian 9 and I've noted since ever that it doesn't change automatically the audio device from HDMI to internal speakers when I plug/unplug the HDMI cable then I need to do it manually.

How can this problem be solved?

Thanks in advance for the help.

Which version of PulseAudio is in use here?

Code:

pactl --version

or

Code:

pulseaudio --version

There was a long-standing bug describing this behaviour ie auto-switching works on HDMI connect, but not on disconnect. Apparently resolved in PulseAudio 12.99.1.

Some additional thoughts...

1. As per this comment I wonder whether explicitly setting the default sink to the internal speakers would help.

2. Just in case this is helpful as a possible workaround...

I'm sure this script could be adapted to work for the case when disconnecting HDMI.
