Alsa volume control in background

[the-gimp-master]

Can you have Alsa loaded in the background ? So anytime I need to adjust the volume using my keyboard with the up and down arrows.

That already happens.

Refer to the picture I posted in your I2S thread yesterday: this time left click the speaker icon, & as you press either volume up or down on your keyboard (in my case they're shared with F6 & F7 function keys), the vertical slider will raise or lower & adjust the volume accordingly.

So you have 2 visual plus audible feedback that volume is changing.

That was one of my first surprises with the Pi, the basic media buttons worked without me doing anything..

But what if your not using desktop.

You can check is alsa is running with

Code: Select all

ps -ef|grep alsa

You will probably get two lines return, the first (in this example) is showing the alsa daemon is running, the second is your search and irrelevant.

Code: Select all

Whilst omxplayer is playing your tune, press your keyboard + key to increase the volume, - for the opposite.
