Floating Audio Level Controls - using yad

[stemsee]

Provides Individual floating, audio level and equaliser (hardware or alsa)controls with mute switches. Each called from a neat six button panel with clear labels. BT, Volume, EQ, Alsa EQ, Mic and Profiles. Each can create many individual controls. Each time you click you select the channel/s to control. BT device must be set as default audio card first using saved Profiles.

interesting little utility! I am going to try it out in some places

[MochiMoppel]

Using FP96. None of the buttons works here.

Code: Select all

amixer: Unable to find simple control 'Playback Digital',0
amixer: Unable to find simple control 'Headphone',0
amixer: Unable to find simple control 'Capture Digital',0
amixer: Unable to find simple control 'Mic',0

[mikewalsh]

@stemsee :-

Neat idea. However, as Mochi has found out, this is very much going to be hardware dependent.

I've even had different Puppies, running on the same machine, that report a given function of the exact same audio chip in a totally different way.....necessitating modified lines in my own QuickAudioSwap utility on a "per-Puppy" basis.

Experimentation - and editing! - will, I strongly suspect, definitely be needed. And as I've discovered for myself - using the man pages - the permutations/combinations of various 'switches' & 'flags' for some aspects of ALSA functionality seem to be ENDLESS.

NOT criticism, you understand. Just observation, tempered by my own experience....

Mike.

[stemsee]

@MochiMoppel@mikewalsh Maybe generating a list of selectable controls from 'amixer' might help.

[mikewalsh]

@MochiMoppel @mikewalsh Maybe generating a list of selectable controls from 'amixer' might help.

Mm. Yah, sounds like a plan. It would give you a 'baseline' set of controls for the utility to work FROM in each Puppy. Which should make it easier to "initialize", perhaps?

Might also make it possible to enable 'user-selectable' controls, so the individual can generate their own custom 'control panel'. (Just throwing out ideas, here...)

Tell me if I'm getting ahead of myself!

Mike.

[fredx181]

For me only Headphones worked.

How can we discourage you from spending your precious time on trying to make this work ?

Ah! ... well ... I don't know how!

@mikewalsh
'amixer scontrols' into a yad list.
single click gets selection info with "amixer get '$selection'", maybe 'tree expansion' can be used here....not sure....i never used it.
user decides to create floating control with a doubleclick!
Control is created but, mute and or level might not work as expected!
But every control has either a toggle switch or a level, some have both, but none have neither!!!
Hopefully, the extra control will have no effect .... according to my brief tests it doesn't.

Yad --form with multiple :scl fields cannot work in realtime (without resorting to xdotool or something to read the scale setting), multiple mute switches can. So either individual floating units per control or use another front-end like gtkdialog or qt....but that's beyond my objective and skill.

[stemsee]

One motivation for this tool is that alsamixer cannot be used directly with a touch screen only device.

control selection list example, double click to mute!

Code: Select all

 amixer scontrols  | grep -e 'Playback' -e 'Mic' -e 'Speaker' -e 'Headphone' -e 'Headset' -e 'Mixer' -e 'EQ' -e 'Master' -e 'Vol' | grep -v -e 'Filter' -e 'filter' |  cut -f2 -d"'" | yad --list  --columns=1 --column=Selection:txt  --select-action="bash -c \"create_gui "%s" \"" --dclick-action="bash -c \"amixer set "%s" toggle \"" &

Here is a huge update!

Four controls for card 0, one controller for card 1 (my bluetooth speaker), and one reset button when wanting to reselect controls for each widget.

The selection bar opens as usual, after clicking on a button a yad list channel select opens to choose which control to pass to the widget. Then the actual widget opens.

The Master Volume widget has two sliders, left and right volume, to give balance control, plus mute and unmute buttons.

Bluetooth audio controls is difficult to implement automatically.

For bluetooth, on fatdog at least, it is necessary to connect and set it as the default soundcard. Then you can use

Code: Select all

amixer -M scontrols

to select device controls.

This update handles bluetooth better!

This is evolving.

Now there is the ability to replace your /root/.asoundrc profile which on fatdog sets your default soundcard, some apps will only play audio through the default system card, like browsers! By copying your .asoundrc for each card and naming*.asoundrc the 'setter' will list them and selecting one will copy it to /root/.asoundrc. It works instantly to set your default profile, so you can set it then start an app. Then set with another profile and start another app which then uses that profile. Control the sound sent to different bluetooth devices and or speakers. I tested with a bluetooth speaker, bluetooth earphones, and builtin sound card. Each time I started a vlc and each one played with the set device. Probably only useful on fatdog. Any way this code will now be included in S.N.ApP

Next update has multiple selections. This primarily helps to create mono or stereo pairs in sequence....my 5 band hardware equalizer now configures with 3dual channel sliders.

Now can provide controls for the alsa equaliser which has 10 bands, actually 20 - 10 left and 10 right, but for now we just use them as 10 pairs.
