[gentoo-user] Plasma sound devices

[gentoo-user] Plasma sound devices

[Peter Humphrey]

Hello list,

Over the last few days I've trimmed my plasma setup - to slightly below the 
minimum, by which I mean that sound notification has stopped working. I can 
hear streamed radio, but the plasma control panel doesn't show any devices so 
I don't hear notifications.

I've scanned the list of packages I removed but I can't see a likely suspect, 
and google just returns results about having no sound at all, which is not my 
case.

Can anyone tell me which plasma module I need to install to hear notifications 
again?

Again, the hardware and low-level drivers are fine: it's just plasma that's 
missing a component.

Regards,
Peter.

I have the kde-plasma/plasma-meta installed here, although I do not run the 
plasma desktop.  It has the USE flag pulseaudio enabled, which I suspect is 
needed to get things like desktop notifications working:

[+ C    ] pulseaudio
    kde-plasma/plasma-meta: Install Plasma applet for PulseAudio volume 
    management
        [+  ] (5) 5.13.5 [gentoo]
        [+  ] (5) 5.14.3-r1 [gentoo]

For what it's worth, I don't have PulseAudio at all on my system and plasma 
still does audible notifications. I think Dale may be closer to the 
solution with the suggestion about kmix.

Could you be missing Kmix?  Since it controls volume/mute settings, I'd
think it would be needed, maybe anyway.

Good idea, but no cigar.

Mick suggested pulseaudio. I don't think it can be that because there's no 
sign of it in my backups; neither in world nor under /etc/portage. I'll try it 
though; I just need to decide whether to set the USE flag globally or just on 
certain packages - or just emerge pulseaudio. The global setting causes 10 
rebuilds, including ffmpeg and firefox, as well as 9 new packages, so don't 
hold your breath.

That didn't help either. In fact I had to install phonon-gstreamer.

I hope that helps somebody one day.

Interesting ... I don't have phonon-gstreamer, but media-libs/phonon with 
USE="pulseaudio vlc", which brings in media-libs/phonon-vlc here.  Either way, 
one or the other phonon backend seems to be necessary to be able to produce 
sound.
