Audio Stops Playing Briefly When Emptying Trash

[Kashif Khan]

I am running Ubuntu 19.10 and encountered this issue. I had a podcast playing in the background on Firefox v. 70.0.1 and I was deleting some files. I then proceeded to empty the trash and saw that the audio stops briefly till the "Empty all items from Trash?" prompt shows up.

I was able to duplicate this many times and it even occurred with audio on Chrome.

The expected way for things to work would be the audio keeps on playing, if I just empty the trash.

Thank you for your bug report.

- What sound card/driver do you use?
- Could you add your '$ journactl -b 0' log to the bug?
- Do you get the same problem if you play a sound using 'paplay'?

[Kashif Khan (kashifk)]

sound card/driver :
Audio device: Intel Corporation Cannon Lake PCH cAVS (rev 10)
 DeviceName: Onboard - Sound
 Subsystem: Hewlett-Packard Company Cannon Lake PCH cAVS
 Flags: bus master, fast devsel, latency 32, IRQ 143
 Memory at a3510000 (64-bit, non-prefetchable) [size=16K]
 Memory at a3100000 (64-bit, non-prefetchable) [size=1M]
 Kernel driver in use: snd_hda_intel

I wasnt able to get any of the MP3 files to play via paplay

[Sebastien Bacher (seb128)]

You should be able to try to e.g
$ paplay /usr/share/sounds/freedesktop/stereo/dialog-information.oga

[Kashif Khan (kashifk)]

tried that and the sound ends too quickly for me to delete the file and test

[Sebastien Bacher (seb128)]

can you try with?
$ aplay /usr/share/sounds/freedesktop/stereo/service-login.oga

[Kashif Khan (kashifk)]

No did not experience it with paplay

I think the more relevant thing to investigate here is the GUI used to empty the trash... Are you doing it via the desktop icon or via a Nautilus "Files" window?

Probably both gnome-shell and nautilus are pulseaudio clients one way or the other.

[Kashif Khan (kashifk)]

Im doing it via the desktop icon. Ive also noticed stops in music or freezes when Im running CLI commands such as update etc.

[Daniel van Vugt (vanvugt)]

OK. It sounds like the desktop-icons extension blocking is the main problem here. A secondary problem, which might be an unfixable design choice, is that it sounds like PulseAudio clients can block the sound of the entire server.

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

Does the same thing happen if you try to shift+delete something in Nautilus? (this also causes a dialog window to pop up)
I have a very similar issue if I play music in foobar2000 through Wine using its "wasapi shared" output method and do that - the sound stutters for a brief amount of time.

If that's unfixable, then perhaps it makes sense to remove this behavior from clients which are bundled with Ubuntu, such as Nautilus. They don't have to block the sound of the entire server, right?

[Kashif Khan (kashifk)]

Another update, Ive seen this have a video/audio running, start a new terminal, type in sudo then tab to autocomlpete, and the audio/video will stop. Now without closing the terminal, when you tab to autocomplete again audio/video keep on playing as expected.

Close the terminal, open new terminal and try steps again and audio/video will stop for a second
