The ‘Audio not working after GPS use’ bug is still there on my Xperia 10 iii with Sailfish flashed on top of Android 13 with 12_4.18v2a blobs.
Stopping pulseaudio and ngfd and restarting them as described by @jovirkku does indeed restore audio.
I also have something like up to 7 apps open, none of them appear to be particularly memory hungry.
Audio loss does not happen after every use of GPS, but frequently.
I also used the script ‘Collect Persistent Logs’ as suggested by @jovirkku. Shall I provide the generated log tarball?
