gutsy-7.10-dekstop (final release) live CD same problem. The button is detected, but the sound is not muted.
In the mixer (Volume Applet 2.20.0) I see that the Master channel is muted, but the sound still plays. Even if I manually mute Master in the mixer, the sound is still playing. If I mute the PCM channel, then it works (sound is not to be heared any more) [EMAIL PROTECTED]:~# dmidecode -s system-manufacturer Hewlett-Packard [EMAIL PROTECTED]:~# dmidecode -s system-product-name HP Compaq nw8440 (RH415EA#ABB) [EMAIL PROTECTED]:~# dmidecode -s system-version F.0F the audio hardware (judging by mixer window) is : HDA Intel (Alsa mixer) the loaded kernel module is snd_hda_intel -- mute multimedia button in macbook doesn't work https://bugs.launchpad.net/bugs/138227 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
