dwm volume control

dwmconfig.h

/**
 * config.h 
 * ALT + F11 | F12 
 */

static const char *upvol[]   = { "amixer", "set", "Master", "3+",     NULL };
static const char *downvol[] = { "amixer", "set", "Master", "3-",     NULL };
static const char *mutevol[] = { "amixer", "set", "Master", "toggle", NULL };

static Key keys[] = {
	{ MODKEY,                       XK_F12,    spawn,          {.v = upvol   } },
	{ MODKEY,                       XK_F11,    spawn,          {.v = downvol } },
	{ MODKEY,                       XK_F9,     spawn,          {.v = mutevol } },
};

Same thing, but with API instead of commands.

Thanks brooo !!!! Nice work!

This is exactly what I was looking for. On my system, the numeric range for the Master volume is large:

Limits: Capture 0 - 65536

So I needed to explicitly user percentages instead:

static const char *upvol[]   = { "amixer", "set", "Master", "10%+",     NULL };
static const char *downvol[] = { "amixer", "set", "Master", "10%-",     NULL };

(And with 10% increments, it's really speedy to adjust.)

Thanks for this!

Thanks for share!

Thanks a lot for this!

A totally seperate issue,
my keys from F1 to F12 don't work in dwm, work in every other window manager/desktop environment

I find it very surprising when people find seemingly simple things very useful. I'm happy that it's useful for others.

Sick!

what if i login as non root user, the upvol and downvol didn't work for me
if i try sudo amixer set Master 3+ null, on terminal it worked,

Great

If anyone's wondering why the vol up and down aren't working for them, just use sudo amixer in place of amixer

for people that use pamixer instead of amixer

 static const char *upvol[]   = { "pamixer", "--increase", "3", NULL };
 static const char *downvol[] = { "pamixer", "--decrease", "3", NULL };
 static const char *mutevol[] = { "pamixer", "-t",              NULL };
