Volctl Fails to Launch at System Startup

[raven2cz]

I primarily use AwesomeWM. I have a script that repeatedly checks if Volctl has been launched and attempts to start it three times in succession. Despite this, it often fails to launch. Specifically, it might successfully launch only 2 out of 5 times. The success rate seems dependent on Pipewire or some other services, but I cannot pinpoint the exact cause of the issue.

I have been encountering this problem for at least six months; previously, I had no such issues. I would appreciate any assistance to resolve this, as I'm puzzled about what could be causing these launch failures. When I manually start it after the system has booted up, it launches immediately without any issues.

Sounds like some race condition. volctl depends on PulseAudio (or the pipewire-pulse service) and the system tray/dbus to be available, depending on the systray protocol you are using.

It would be helpful if you could provide a console log of volctl to be sure what the underlying issue is.

Is this different from https://github.com/buzz/volctl/issues/81#issuecomment-1695075292? If no, then we should continue the discussion in the original issue #56 to keep things tidy.

This doesn't seem to be related to this issue at all. In your case, reinstalling volctl should help. Python was upgraded to 3.13, and your volctl installation is for an older version, would be my guess.
