DAC sound card or nothing?

[VeteranGamer]

I already have some PAM8403's or whatever because I intended to use GPIO sound. The sound was so distorted and had so much interference (even after making a filter) that I decided to just bite the bullet and do the USB hub and sound card. I know emulation won't give perfect sound, but it's worth the extra 15 bucks to be happier with it.

the USB audio setup should sound a lot better than PWM audio....

its definitely worth the effort

So I plugged in the hub and sound card and my headphones straight to the sound card headphone jack and I hear nothing. I made the /etc/asound.conf file and referenced 003, which is the device number from lsusb. Verified by unplugging and checking it again.

Is there another step I'm missing? I feel like it's something obvious...

have you set the volume....

Opening that menu item I am confronted with this...

I then get to the picker with Auto, Headphones, HDMI and mixer options. Picking mixer to adjust volume quits back to RetroPie.

Maybe I screwed up that audio file I made?

Code: Select all

      pcm.!default {                                                                                                     
      type hw
      card 003
   }
   ctl.!default {
       type hw
       card 003
   }

i'm not actually certain....
its trying to find your card,but card (you've assigned it wrong)


but try this.....

pcm.!default {
type hw card 1
}
ctl.!default {
type hw card 1
}

Progress!

I now get sound, but it was weird. First I turned it up a bit (before trying, bad idea I know) and it was really loud in the left ear and normal in the right. Turned it down a few notches. Now really loud in right and normal in left. Turned down again. Now comfortable in both ears.

I now get a new error whenever I enter the audio controls or enter a game.

It says
lvl0: Volume control::init() - Failed to find mixer elements!

Hoping I don't have to do the recompile thing. Would you recommend that, or maybe try Fleders thing about creating .asounrc file?

UPDATE:: Turns out the volume between ears likes to change between launches whenever it feels like it. This has to be a symptom of the mixer issue, right?

These cheap sound cards will overheat and kill headphones because they lack a DC filtering capacitor as a cost-cutting measure. There are several guides on how to add said capacitor out there.

the sound card already has an headphone out....
so the headphone aspect shouldn't be an issue.....

and im pretty sure other members have used this sound cards in many builds....

but if you think there are guides to make things better, it would be nice for you to actually share them....
