strange behaviour in AlsaMixer

[Member seriousness]

When I start AlsaMixer after booting, the Pre-Amp slider is not present. When I start playing music with audacious, it’s there but not moveable. Then I pause audacious and continue playing and now it is moveable. Is there something wrong with /etc/asound.conf ?

live usb? persistence? installed system?

my understanding is that pre-amp appears the first time you send sound, but after that its should be a regular slider.

I executed
sudo alsactl store
and rebooted. Now all AlsaMixer settings are restored, including Pre-Amp.

Edit: sorry, I forgot to mention that I’m on an installed system.

That solved the issue only half-way. On boot the settings are restored from /var/lib/alsa/asound.state which I manually saved, but the file is not overwritten with the current settings when I turn the computer off. To me it looks like the alsa service is not running.
I found this command:

$ sv status alsa 
fail: alsa: unable to change to service directory: file does not exist

I am new to runit and do not yet understand, how services are managed.

Finally, I got it working!

In /etc/runit-core/ I created a symlink to S17alsa-utils named K17alsa-utils.

Now AlsaMixer settings are stored on shutdown and restored on system start.

Alsa is not a service it’s a sound driver, also sv is not installed by default with antiX.

To check a service with antiX run below.

sudo service mpd status
mpd is running.

Service commands for antiX

sudo service --status-all

To start service

sudo service mpd start

To check status of service

sudo service mpd status

To stop service do

sudo service mpd stop

To relaod service (i.e. stop + start ) do

sudo service mpd reload

Set default sound card…

Open alsa mixer with sudo press F6 or S select your card then type sudo alsactl store.

sudo alsamixer

sudo alsactl store

and OR

Setting the default device
Jump to: navigation, search

Find your desired card with:

cat /proc/asound/cards

and then create /etc/asound.conf with following:

defaults.pcm.card 1
defaults.ctl.card 1

Replace “1” with number of your card determined above.

My sound system—

cat /proc/asound/cards
0 [HDMI ]: HDA-Intel – HDA ATI HDMI
HDA ATI HDMI at 0xfcda0000 irq 95
1 [US2x2 ]: USB-Audio – US-2×2
TEAC Corporation US-2×2 at usb-0000:0b:00.3-1, high speed
