Version: 2.6 (using KDE 3.5.4 Level "a" , unofficial build of SUSE ) Compiler: Target: x86_64-suse-linux OS: Linux (x86_64) release 2.6.16.21-0.13-default NVidia CK804 (on board chip) Things that I can achieve with: amixer set IEC958 unmute amixer set IEC958 mute are not doable with KMix (the control is there but it does not work) I can turn the radio box at the switch tab for IEC958 On and Off, but it does not communicate with ALSA. On the other hand, with the Gnome ALSA mixer, clicking on the IEC958 radio box mutes and unmutes the sound. I am using digital output and the "IEC958 Playback Source" pull down menu is set to PCM. Once it works, it might be helfull to rename (or add to name) SPDIF/AC3/DigitalOut to the IEC958 string that is not very descriptive. Thanks and waiting 4 kde 4.
Please send the output from the following two commands: cat /proc/asound/cards amixer PS: IEC958 switch works fine on various other boxes. There must be something special with that chipset.
Created attachment 17937 [details] cat /proc/asound/cards ; amixer This is quiet annoying. Everytime the computer is rebooted I need to enter the console and unmute manually ( amixer set IEC958 unmute ) and then go to kmix>Mixer>AC97 and lower the slidbar to the minimum. With 0 works, with 1, 2 or 3 not. Maybe is the normal behaviour, but the setting is lost and every time I log in, it resets back intself to 3. Other alsamixer front ends do not have this problem: Gnome ALSA mixer, gmerlin_alsamixer, etc.
OK, I see from the submitted data that this chipset has a capture switch and a playback switch. KMix does not support this yet (and it is a bug).
More precisley, the 'IEC958' looks like this: Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined cswitch cswitch-joined I now see that this is exactly the second issue in bug 126012. So I'll mark this as DUP. Target milestone: KDE4 *** This bug has been marked as a duplicate of 126012 ***
