dvol - dzen2 volume bar (good for multimedia keys and tiling wms)

supulton · 2010-08-08 09:44:37

my main mixer control (PCM) is unable to use the 'toggle' function for some reason i've never investigated, so i modified the script to set the volume to 0, then back to the previous volume.

hya guys

using paldepind example script and it works like a charm apart for the fact i get no % text just the icon and bar..i have terminus installed and dzen2-xft-xpm-xinerama-svn ..any idea why

thx

Yeah, you're using svn. The svn version only shows the bar, while the stable release shows percentage+bar. This is why I keep an old gdbar around, only dzen2 itself is from svn, so I get xft. That, and the old gdbar has a conky-style bar.

I have modified the script so as to handle pulseaudio.

Hi guys,

Very nice script ! But I have a problem with the files .pulse/volume & .pulse/mute. If you change something in pulseaudio via mpd for exemple, the volume or muted state are never write in the files. So why not grab the volume and the muted state in pacmd ?

For the volume :

# Get current volume. return a %
function get_volume(){
    MIXER=$(pacmd list-sinks 0 | grep -i "volume: 0:")
    echo $MIXER | cut -d ' ' -f 3 | cut -d '%' -f 1
}
# For the real volume, you have to * 65536 / 100
VOL=$(get_volume)
CURVOL=$[$VOL * 65536 / 100]

For the muted state :

# Get muted ? return yes or no
function get_muted(){
    MUTED=$(pacmd list-sinks 0 | grep muted | cut -d ' ' -f 2)
    echo $MUTED
}
MUTE=$(get_muted)          # Reads mute state

And you juste have to change "false" by "no" in

if [[ $MUTE == "false" ]]

Thx for the original script, my xf86audio keys are happy now

jeetu · 2011-08-18 15:13:54

I m pasting the new script with the recommended changes.
Also now the volume bar centers itself accordingly as per the resolution.
But the setting of volume through mpd still does not reflect as the script reads/sets the main output volume, but mpd sets/reads the application volume. (Correct me if I am wrong as I am new to pulseaudio)

Using this with PekWM. Works GREAT.

hey guys! how did you find out which were your keys? I'm using dwm/monsterwm. I remember I used something like XF86audioMute or something like that, for the key's name in the config file.

Gusar · 2012-01-28 18:18:56

They're always the same: XF86AudioRaiseVolume, XF86AudioLowerVolume, XF86AudioMute

The command `xev` could help you find that out, as well.

I dont get how this works. It does change volume, but the dzen stuff is not working. I only get a completely purple rectangle, which always looks the same.
Also what is "dzen2-gdbar"?

One small improvement:

if [ ! -p "$TMP_FIFO" ] ; then
    [ -e "$TMP_FIFO" ] && rm "$TMP_FIFO"

instead of

if [ ! -e "$TMP_FIFO" ] ; then

Mhh, I get an error but it shouldn't be that critical, what might cause this? Dvol script still works.

What's the output of

sres

?

bloom · 2012-09-27 15:40:11

It is rare, but multiple instances of dzen2 can reach that part of
the code (producing a blank window):

    mkfifo "$TMP_FIFO"
    (dzen2 -h "$bar_height" -w "$bar_width" $xy_pos -fn "$bar_font" -bg "$bar_bg" -fg "$bar_fg" < "$TMP_FIFO"
    rm "$TMP_FIFO") &

This should be replaced with:

    if mkfifo "$TMP_FIFO" ; then
        (dzen2 -h "$bar_height" -w "$bar_width" $xy_pos -fn "$bar_font" -bg "$bar_bg" -fg "$bar_fg" < "$TMP_FIFO"
        rm "$TMP_FIFO") &
    fi

(This has nothing to do with Shinryuu's issue.)

Ah, I didn't notice your question. It seems I solved my issue by fiddling with center_rect where I changed "xoffset and yoffset" to simple pixels numbers.

xoffset=1580
yoffset=52

sres (laptop)

1366x768

sres (pc)

1920x1080

bloom · 2012-09-27 20:56:51

Could you add

echo "$xoffset $yoffset"

after

xoffset=$1
yoffset=$2

in center_rect
And give me the output of

center_rect 300x40

?

Sure and here's the results.

laptop

533 242
533 242

pc

810 346
810 346

I fiddled with center_rect a little bit more and I found this out, I typed "xoffset" "yoffset" lines again and the error is now gone with my laptop, maybe I had an extra empty space/line?
