description |
With this latest update (Linux 5.4.0-58), the sound is now crackling. Feels like DMA buffer underruns, but I'm not sure. Not seeing a significant CPU load that might have aggravated it, nor am I seeing any complaints in syslog or kern.log. Restarting pulseaudio and running alsa force-reload had no effect.
These sound issues started with the same update that caused the ath10k_pci driver to become extremely unreliable (filed as bug 1908106).
