Hi All,

I am looking for a USB soundcard that will work with Raspberry Pi for a
project I am working on, wondering if anyone has any experience with
this and what they recommend to get, only need it mainly for mic/line-in

PPS - I'm on my phone, so can't link you, but anything compatible with the
latest kernel should work.  They've got compatibility down pretty pat, so a
lot will depend on the intended use (ie quality needed).

>>> How come you're not using the line in?

main issue is quality and also having dedicated app tying up the port.
where you also want other app doing general sound output.

One of these works fine for me:

I haven't checked it for the sound quality, but the output was fine into
some Logitech speakers.

Yeah - looked at mine last night.  Pretty sure the audio port works as in
and out, though I haven't tried it yet.  (Some) USB mics work with the RPi,
but I'm thinking it'd probably be cheaper to go with the option linked by
Damien.

Where did you get it Steven?  It looks pretty cool (I'd love to add
something similar to a robot).

that be nice, but I need to run it as cable line-in etc, as be
receiving data from off of the radio that will be decoded via the
RPi ;-)

I have a bought a cheapy off of ebay that looks similar to what Damien
linked to earlier.

Years ago I bought a USB sound card that I was going to add to an
Opensource router and make an mp3 jukebox, but I ended up getting an
AppleTV which served the same purpose.

Neverthe less I still have the USB soundcard.

Which was bought from a chinese vendor on ebay for less than $AU10.

The card says "Model HY554, USB 3D Sound, PnP"

So this morning I plugged it into my Rasberry Pi, running the kernel
that came with the default distro

>uname -a

Linux raspberrypi 3.1.9+ #272 PREEMPT Tue Aug 7 22:51:44 BST 2012
armv6l GNU/Linux

this is what dmesg told me when I plugged it in

[  254.921267] usb 1-1.2: new full speed USB device number 6 using dwc_otg
[  255.022766] usb 1-1.2: New USB device found, idVendor=0c76, idProduct=1605

Device [SSS USB Headphone Set] on usb-bcm2708_usb-1.2/input3
[  255.381456] usbcore: registered new interface driver snd-usb-audio

When I looked in alsamixer it appeared in the list and seemed to be ready to go.

But I didnt test to see if I could record.

Isnt it great when something "Just works"

Maybe if you found one of these dongles on ebay it might solve your problem

it has two audio jack ports, one for headphone and one for microphone

given that it is 3d it must have some sort of 5.1 encoding also.

I am also planning on experimenting with this on my mk802 under android.

But I dont have a USB hub at the moment.

If you are really keen I can let you borrow it for a looksee, but I
want to keep it.

Sam

Sorry, but this looks identical to the card I have

http://www.ebay.com/itm/Nw-Blue-External-USB-2-0-to-3D-Virtual-Audio-...

Except mine has a grey trasperant case not a blue transperant case, If
you are curious I can take out a camera phone and send an image of
what it looks like.

Audio is one of the standard USB classes specified in the standard.  
Assuming the device doesn't try to do something fancy or stupid, it will
use the documented protocol and should work.

> it has two audio jack ports, one for headphone and one for microphone

Someone was looking for an input... I think mine is only a mono input.  The
only time I used the input was when I tried to use it as an oscilloscope.  
Maybe you could use the USB device as an output and use the built-in jack
as an input (assuming it supports that).

given that it is 3d it must have some sort of 5.1 encoding also.


I doubt it... it's probably marketing crap!

Someone can borrow mine too if they want.

Just tested with Audacity under raspbian and I was able to record
(mono) audio from my two dollar shop microphone and play back the
sound both via the USB headphone dongle, was a little muddly because I
had to choose two of the keyboard mouse and sound card, but not all
three at once, cant wait for the powered usb hub to arrive from China.

I think it might be limited to mono audio and it seemed to take a fair
bit of CPU to record in Audacity, but I couldnt remember any command
line audio software, so all the CPU was probably taken up with the
meters and waveforms.

Good little hack while making cheese on a Sunday afternoon.

Does your Pi distro have "arecord"?

"aplay" and "arecord" are commandline tools to record and play when using
ALSA (which is likely).

In case anybody is interested I found out that this USB device didnt
work as a microphone for Skype for mk802 with the default Android
4.0.3 that came with the device

I will flash it when I can bring myself to putting windows on a box,
seems that the only option to flash the card easily is under windows.

Having the mk802 work as a turn key device for Skype is of interest to
me to put older relatives overseas without computer smarts in contact
with each other via video chat its probably flawed without a computer
network in the house but a 3g hotspot could be sourced.

To use arecord you need to get the options right. With my Sound Blaster USB card this works:

arecord -D hw:1,0 -f S16_LE -c 2 -r 48000 tmp.s16

It records raw PCM data at mono at 96000hz, but at least it works
