Usb soundcard

Fri Apr 13, 2018 8:05 am

As most of us know that the audio output on the pi is only about 775 millivolts which is right for using headphones but what if you needed a higher voltage output possibly around 1.5 volts or higher which is the spec of most CD players etc use
So on that note is there a recommended usb soundcard for output not input for the raspberry pi

I believe you can buy any usb audio card, pick the cheapest from ebay. These cost a buck and a bit. The quality of the Pi's audio output is not that great from what I've heared, so a usb audio card is a good idea.

If you want to drive speakers, you still need to use an amplifier

I would give it a try fist.

I was very impressed with the audio output of the 3b+. Very low noise, its good enough for my stereo.

Make sure to raise the volume in the pi to max. Default ist 50%

The OP has not said that he is using any form of a display. As far as I can tell he is simply making a headless audio player. And to get an hdmi audio extractor is like 20x more expensive than a usb soundcard.... especially if no no hdmi display is used

spi audio for £2
usb for £1 ish

I made a Pi Musicbox player using a Zero and a WD Labs Node Zero hard drive. It has a USB sound card with phono out put which connects to my home cinema amplifier. It works well, the sound card is Ugreen and came from Amazon.

Now I'm wondering if I could have used the HDMI socket to get audio. The player is headless, controlled either from my laptop or tablet so I'm not using the HDMI socket.

you need an audio extractor to get the audio out of the hdmi stream

To answer one question about the HDMI out
Well that is being used on a computer monitor at the moment
