Only getting Dummy Output audio after resuming from suspend
Summary
After upgrading from Kubuntu 19.04 to Kubuntu 19.10 I've started having issues with only having a Dummy Output sometimes when resuming my PC from standby. I've noticed that this issue seems to occur somewhat randomly after some resumes but doesn't happen during others. Running pulseaudio -k
always fixes the issue and it never occurs on a power-up or reboot.
Running journalctl --since "1 day ago" | grep pulseaudio
after resuming my PC from standby gives the following output:
Nov 10 21:30:44 Linux-PC pulseaudio[3005]: W: [alsa-sink-ALC1150 Analog] alsa-util.c: Could not recover alsa device from SUSPENDED state, trying to restart PCM
Nov 10 21:30:44 Linux-PC pulseaudio[3005]: W: [alsa-source-ALC1150 Analog] alsa-util.c: Could not recover alsa device from SUSPENDED state, trying to restart PCM

environment
I am using Kubuntu 19.10 as my operating system with kernel 5.3.0-18-generic. I use both an optical output and an analog output for my sound.
I also have the following modifications in my default.pa config:
load-module module-echo-cancel source_name=noechosource sink_name=noechosink
set-default-source noechosource
set-default-sink noechosink
The bug occurs with and without the modification
Steps to reproduce
- Suspend your PC
- Resume it from suspend
- Temporary fix can be performed by running
pulseaudio -k
What is the current bug behavior?
The alsa device cannot recover from a suspended state causing a Dummy Output to be the only available audio device upon resuming.
What is the expected correct behavior?
The audio devices that were available/used before suspending being the same after resuming.
