Default Cheap USB- soundcard for raspberry pi

Hey Guys,

What do you think about this cheap soundcard to obtain a digital output out of the raspberry pi:

Raspberry Pi • View topic - Tip X-Mas Gift No. 1

...see further informations:

http://www.aliexpress.com/item/PCM27...654055749.html

I would use only the digital out.

Is the quality enough if i connect it To a good DAC....(2496 mini dac)

I'm using only mp3 sound (320kbps) and no superior quality lossless flac aso...

Thank you

Knorst

Thats what I use with my Raspberry PI. I use MPD with a wireless NIC for a music streamer - play music off my desktop PC. It works great in my workshop - my amp and speakers which are just OK are the quality are the quality bottleneck - not the PI and DAC. I recommend for $13.

OK great...

But do you use a separate DAC via digital output or the direct analog outpt of this cheap device?


My question is, if this cheap device would also be suitable for a setup with an extra DAC,amp and speakers with quite good quality, but no superior equipment, if I'm using the digital output.... Connected to a good DAC...

It should compare to the sound of an airport express connected to the same DAC via toslink optical

ThAnks for your answers...
Regards
Knorst

I just run the direct 3.5 mm to RCA out into my Amp. No need for a second DAC - that would be redundant. I was pleasantly surprised with the quality. I use in my workshop with older HT receiver and cheap bookshelf. The device would only be a sound quality bottleneck in a much higher-end system.

Well ok thank you....

but my question goes in a different direction:

is the PCM2704 in combination with the raspberry pi using the spdif output of the PCM2704 able to provide high quality digital sound up to cd quality to feed a good DAC and a good amp/speaker system...with quite good Canton speakers (Ergo RCL, old but still good!)


thanx for further answers...

greetings knorst ;-)

My personal experience says don't even bother.

Go for an android box with a dac of your choice. 10-20 euros more expencive but works out-of-the-box. Plus it makes an excellent-even superior-squeezebox replacement.

Thank you,

but i was very interested in this project:

SqueezePlug

which should work mor or less out of the box...

what were your problems? are they related to the audio capabilities of the raspberry pi?


Does a android box work via a remote app, without the necessity to use a screen...


greetings

No matter what you read on "guides" you will have to go through some programming.
You will face "unexplained" problems etc. Pi is still tricky, not mature enough as a product to work out of the box. But of course this is one of the reasons that it is so cheap.

Analog audio out is to my ears very bad.

USB output (probably this is what you will use to connect your DAC) is simply FULL of problems. Just google raspberry usb audio output.

Pi is great as a next level for those who use arduinos, pics, msp's etc eg for robots. Not for anything else.

If you want something to play with then by all means go for it. If what you want is something to connect and play and be in peace but still have the option to tweak then an android box is the way to go.

which is more expensive but it is exactly what I was looking for.

but this will also work. http://www.amazon.co.uk/Klastor-Andr...keywords=mk808
