Description Silviu Marin-Caea 2011-03-14 15:19:05 UTC

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:2.0b12) Gecko/20110222 Firefox/4.0b12

The default KDE4 mixer has only very basic features.  That is, it cannot access all the channels.  Practical example:

I have a computer with mainboard GeForce 8200.  It outputs video and audio through an HDMI cable to a Full HD Philips TV.

By default, after installing 11.4 the audio HDMI channel is muted.  There is no way to unmute it (and keep the setting) using the KDE mixer.  "Configure channels" shows one one option, "Internal audio"...

The only way I could find is by running alsamixer in a terminal window and unmuting the SPDIF channel.  But this setting is lost after reboot.

I had 11.3 on this system until 11.4 was released and there was a way to do this unmuting in KDE.

Reproducible: Always

Steps to Reproduce:
1. Install 11.4 with KDE 4.6
2. HDMI audio output is muted by default
3. no way to unmute in KDE, have to use alsamixer.  This is a usability issue, no discoverability.  You cannot click around and resolve the problem.  You have to know about alsamixer.
Actual Results:  
No way to unmute HDMI audio output in KDE.

Expected Results:  
Everything should be configurable in KDE, either KMix or in KDE "Configure Desktop/Multimedia"

I think this has something to do with the new default sound daemon pulse-audio

Comment 2 Christian Trippe 2011-03-14 20:29:30 UTC

This sounds basically like bug 674372. Do you agree? (And you can also tray pavucontrol assuming you use pulseaudio.)

Yes, I'll mark as duplicate and add my comments to that bug
