Just upgraded from PA 6 to 7 today, and now audio keep getting dropped. I've had this problem in some video games and music players:

Playing: /home/rowan/Music/Dissection/Storm of the Light's Bane/05. Retribution - Storm of the Light's Bane.opus

I'm having the same problem too

Having the same problem with spotify client (, chromium (45.0.2454.101-1), and google-chrome (45.0.2454.101-1).

I may have found a possible work around. As described on, disabling shm (aka srbchannel mechanism) appears to correct the issue with Netflix on google-chrome. I have not yet tested spotify or chromium.

This may also be of interest. tanuk on #pulseaudio suggested recompiling pulseaudio with two commits [1][2] may also resolve issue with terminated connections. The first four patches are already merged according to tanuk's response to a bug report [3]. My attempts to compile pulseaudio 7.0-2 through ABS ran into dependency conflicts.

Here's a followup.

Disabling shm in pulseaudio was an unexpected fix for tanuk. The problem firejail has is depriving the jailed app of the `/dev/shm/pulse-shm-xxxx` file it expects. I'm not using firejail, so what fixed my problem? Time to back-track.

I updated my `~/.config/pulse/client.conf` and removed the `enable-shm = no` setting. After a `pulseaudio -k`, I found I could not reproduce the connection terminated issue, which indicates that messing with the shm setting may not have an effect. About the only other thing I did at the time was `pulseaudio -k` to restart pulse after adding the setting. Media apps are still working fine so far.

I think adding `enable-shm = no` to `~/.config/pulse/client.conf`, then `pulseaudio -k` as suggested by Justintar worked for me

Still experiencing this problem, even after setting `enable-shm = no`.
