Alsamixer-Qt 0.4.1 available

[Sebastian H.]

Hello again

This is a bugfix release. Not all issues have been addressed, but
hopefully the most annoying ones.

1.)
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3678

The "EQ Peaks" mixer element gets skipped since there's not way to
display it correctly at the moment.
Also the mixer now looks for all element channels from 0 up to
SND_MIXER_SCHN_LAST (= 31). Formerly it was only for the first 9 channels.


2.)
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4204

Raymond brought this up but I'm not entirely sure what's the problem
here. Are there actually 5 controls named "Master" on this card?
If so alsamixer-qt4 now appends the element index to the element name
for elements whose name appears more that once. This should happen for
all elements but I could only test it for "Capture" and "Input Source".
Both appear twice on my HDA-Intel onboard card.

Comments are welcome!

The main problem  is this EQ peak control is read only and your
alsamixer-qt4-0.4.0 generate a lot of error messages when the user try to
move the slider , so the only way is to skip the volume control or implement
the equalizer peak using 10 qt4 vumeter widgets

[EE] EQ Peaks: snd_mixer_selem_set_playback_
volume_all: Operation not permitted





For CMI8788 , there is only one Master volume control controls with 8
channels volume control but it seem only has one mute switch

In 0.4.1 the "EQ peak" should be hidden. But that's a temporary
solution. I just don't have a card right now with "EQ peak" and
implementing a feature/widget that I can't test is not too much fun.

Ok, then I don't see a any problem there.
