Quite difficult to reproduce is the following behaviour:
if I press the Vol+,Vol- or Muite buttons (located above the numeric keypad), OSx displays the correct overlay window (just like the eject or brigthness adjust windiows), but below the volume bar, I see the disabled/not allowed icon.
Thus, these keys seem to work (at least they generate an event processed by OSx), but I didn't find any way to get them enabled again.
What works fine is the standard menu-sound-control or system settings/audio.
just a few days ago, unfortunately I don't remember any different behaviour from my side. It happend also some time ago, but I'm not sure how I got it fixed.
- Sound setups
- Internal soundcard
- USB headset (mike / speakers), but no change if this is pugged in or not
I don't expect a first hit on this, but would be more than happy to have some advice to dig into this further.
Many thanx in advance,
