USB speakers?

Postby ian2000t » 15 Nov 2015, 20:49

Is it possible to run RuneAudio on Raspberry Pi from USB speakers?

I have a RuneAudio Pi in the garage connected to an amp/speakers through 3.5mm, but the sound isn't great. I get scratchy noise interference from the USB WiFi, and I also get a "robotic" sound occasionally. I might get a HifiBerry for this to improve the sound.

I'm looking to create a RuneAudio powered retro radio, and I need an amp/speaker setup to fit inside the small space, and hopefully without the inference or quality issues. Needs to be cheap though so I don't really want to go HiFi berry + amp.

I have a set of powered USB Logitech V20 speakers. Can these be ran straight from USB without a separate DAC?

Hi ian2000, they should, because... guess what? They must have an internal DAC to play music via USB :) The point is if that DAC will work or not under Linux. As you have them on hand, just try it and tell us the results.

OK thanks, I'll give it a go!

If it works on Linux, should it show up in the "Audio output interface" drop down in MPD configuration?

Yes, it should in that case.

Just wanted to say, my USB speakers (Logitech V20) plugged in and just worked.

Alsamixer also gave bass/treble settings for them as well which is nice!

Not the best sounds, but for a retro-fitted Roberts R500 for the kitchen they'll do perfectly! Will post some pics when it's all together!
