[gentoo-user] alsamixer

[Alan Grimes]

I don't really know why sound is working on my machine rn.

I think there is some kind of embedded USB bus AMD thingy that generates
some digital stream that is simply played by a set of DACs on my mobo.
The chipset listed in the motherboard manual seems irrelevant.

The capacitor in my speakers is dying again, I bought these speakers
back in 2006 and have hardly ever turned them off since. So they don't
have much gain anymore, So I need some boost from the card....

Because I need to change a setting, alsamixer just dies when I try to
configure it. When I try to select USB audio, the thing instantly
crashes to desktop.

atg@tortoise ~ $ alsamixer
cannot load mixer controls: Broken pipe
atg@tortoise ~ $

Excuse top post. Responding from phone.

1) what desktop environment?

2) what shows up under /proc/around/cards?

3) what are the speakers plugged into?

None, I fire up pulseaudio in my xinit script. I'm trying to configure
it with alsamixer as I always have...

Interesting, didn't know about this:

atg@tortoise /proc/asound $ cat cards
 0 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xe1080000 irq 109
 2 [Audio          ]: USB-Audio - USB Audio
                      Generic USB Audio at usb-0000:47:00.1-5, high speed
atg@tortoise /proc/asound $

Just a basic headphones -> RCA adaptor cable from the main output from
the motherboard, it's a surround sound type motherboard even though
those are pointless, you get surround sound out of a computer by
decoding the HDMI output ( see 0 above, ) I do that in the other room...
Anyway, it's a surround sound mobo and I don't have much say in that...

Ok, honestly It's a MSI creator TRX 40 board....

If you're running pulseaudio then try pavucontrol instead of alsamixer to
control the PA server. You might need to emerge it.

I'm not suggesting alsamixer cannot work, but you might not need it.
