"Null Output" showing as name of audio device in Sound

[muammar]

If you are interested in the systray, pass the -t option: python mkchromecast.py -t.

I may have fixed it here da8d1f4. But as I was working in the sonos branch I commited there, and the change is not still there in devel or master. Sorry about that!. I will try to merge sonos back to devel maybe later this week.

[xmbwd]

Wanted to check in on this -- is in dev or master? After a few days of play, I get six different null outputs in my sound prefs, making it hard to figure out which one is live. Appreciate it.

[muammar]

It is in the sonos branch if you want to test the fix. Thank you!.

[xmbwd]

It looks like the sonos branch is only available on OSX. I'm running Linux:

The setup.py is only there for macOs, that's true. But you can just execute python mkchromecast.py from the cloned repository. I should fix the setup.py file.

[xmbwd]

Oops. Got it! Was using setup.py.

[muammar]

Oops. Got it! Was using setup.py.

There are many things I still have to fix :) sorry about that!. Hope that this change fixes the issue.

[xmbwd]

Unfortunately, when running sonos using python mkchromecast.py, it does not appear to fix the null output issue. Running it in terminal does not start the applet, should it?

[muammar]

The change introduced will not create another sink if there is already one named mkchromecast. If this is not working, then something a bit more aggressive should be done (pulseaudio -k see this). But not sure if that is going to be very welcomed.

[xmbwd]

Let me restart and see what happens. There is no sink named mkchromecast, but that may be residual nulls.

[muammar]

Let me restart and see what happens. There is no sink named mkchromecast, but that may be residual nulls.

Yes, that may help to sort this out. On my case, if I kill the application suddenly (using kill -9 processnumber), no new sinks are created although sometimes the only one working after I restart mkchromecast takes the Null Output name. But that is better than having many of them.

[xmbwd]

I restarted and switched sinks. Looks like it is working. I'm not sure why, but sometimes it shows up as mkchromecast and sometimes null output -- sometimes simultaneously (see picture below). In Sound and pavucontrol it seems to usually have mkchromecast. Using sound switcher indicator it seems to usually show null output, regardless of the others.

[muammar]

Thank you. It is exactly the same that happens for me. I will keep using it to see if that can also be improved. Thanks for reporting back!.

[muammar]

Are you still having the issue of multiple sinks or only one sink but having sometimes the Null name?.

[xmbwd]

Sorry man. I couldn't get the delay down short enough so I stopped using it. If I recall correctly, you had fixed that issue in one of the builds.

I should note that I tried to install mkchromecast on a few temporary Linux USBs and was unable to. There is no install on the main repositories and even the deb didn't work for want of a number of dependencies (not the list of ones you have on the main site, additional ones).

[muammar]

Thanks for replying. I really don't remember at what point it was fixed, but I will try again later to solve this issue. I will proceed to close this report.
