S/PDIF output

Post by pukington » Fri Mar 30, 2012 3:18 pm

Will be interesting to see how you get on, there are various USB dacs about so I could be tempted to have a try too.

As i recall my cmedia one worked fine, it was item # 230583551200 on fleabay (can't post link as on phone) having edited the asound file, but as its lost I thought I'd try a different route. Someone here posted a link to it ages ago so I bought one.

Thanks for confirming that the card you mention works. I'm at a PC and the ebay link is http://bit.ly/HpDmWA.
This is the kind of confirmation I've been seeking for months. Oh well, I've bought a different one now. Hopefully it can also be added to the very short list of Joggler-friendly USB soundcards with S/PDIF.

The card I ordered was a Behringer UCA 202 from ebay. Unfortunately, I've received an email from the chinese seller saying that it is out of stock and may take a couple of weeks to arrive at their warehouse. They've offered a refund or say I could wait a little longer; I've not decided which action I'll take.

Is it cheaper than this?:

Be interested to know if it works. Not that I have anything that takes an SPDIF until I buy a new amp. :roll:

Yes, it was about 7 quid cheaper.

http://www.ebay.co.uk/itm/Behringer-U-C ... 165wt_1059

I bought it from the same seller and he is still listing them on ebay, even though his email said they are out of stock. It's probably best to wait and see if I eventually get mine before ordering from him.

I did post this in a different thread, but thought it might be useful info over here - since this is a thread specifically related to S/PDIF out.

I actually own the UCA202 and tested it with the Joggler; it works just fine on the stock OS. I haven't tried it under Ubuntu/Mint/et al yet - I use USB speakers with a built-in DAC under Joggler Mint - but I have used it on desktop Ubuntu installs in the past with no problems whatsoever. If it works on a destop Ubuntu install and works on the stock Joggler OS, I'll go out on a limb to say that it should work fine on Joggler Ubuntu/Mint/etc.

It is TOSLINK S/PDIF, not coax. That suits me just fine, as I have TOSLINK inputs and not coax, but I know there are mixed feelings on TOSLINK.

I was going to buy one of these for the optical output but even at £20 (ish) it would be an expensive item if it didn't work.

I'd love a neat alternative to my current USB card with S/PDIF out, which is currently an ancient VOIP handset with soundcard capability.

I may be slightly biased towards the UCA202 though, as I think it's a brilliant little device! :D I bought it years ago in order to record gigs at a local club (stereo output of the mixer hooked up to the UCA202); it performed that task brilliantly, but it's also turned out to be a great little USB sound card. It's perfect for modding too, because the board itself is quite small, and the case is actually screwed together - none of that epoxy/glue nonsense.

Ive managed to find my cmedia xenta usb soundcard and can't for the life of me get it to go, dont know if i fried it from pissing about with it ages ago but i cannot get the spdif to work.

Gonna buy one of the UCA202 jobs and have a play with that next.


Thanks for the video btw mate, glad to see it works straight out the box!

This

looks like a good well priced USB soundcard that I was considering for my CarPC (voice recognition using 2 microphones).

Any thoughts.....?

My UCA202 soundcard arrived and it worked out of the box with the standard Joggler USB asound.conf file. I've only tried it with the 3.5mm jack so far, but even then the sound is pretty good through a pair of USB-powered Logitech speakers. The DAC seems to be better quality than the cheap C-Media card I had before, although not dramatically so using a pair of small speakers. I reckon I'll really notice the benefit when I hook up one of my Jogglers to the hi-fi. Being able to output through 3.5mm headphone, S/PDIF and phono is a big plus.

I'll report back when I've given it a proper test drive.

According to STAC9202 datasheet, SPDIF signal is available through pin 48 and 3.3V power supply from pin 9.
So I've soldered a spdif connector to my Joggler to test :)

These are devices available on our Joggler :

Code: Select all

# cat /proc/asound/devices
  2:        : timer
  3: [ 0- 1]: digital audio playback
  4: [ 0- 0]: digital audio playback
  5: [ 0- 0]: digital audio capture
  6: [ 0- 0]: hardware dependent
  7: [ 0]   : control
Hi I am looking for some help please.
I've done the spdif coax socket digital output on my joggler but need to programme my joggler so it outputs through this socket to my DAC.
How to I change these settings please.
I have done the download from Birdslikewires onto my the feb 2014 internal download.
I don't no how to get into the programme or do I down load it to memory stick again ?



Card0 / Device1 is spdif digital output.
So I've edited /etc/asound.conf like this :

Code: Select all

pcm.!default {
   type hw
   card 0
   device 1
}
It's working perfectly on Ubuntu ! :P

However, it's not working on stock firmware and I don't know the reason...maybe this is due to old ALSA driver used or another file has to be modified to run perfectly...
Any idea ?

Regards,
ARJunior

EDIT :
Just for information, with Squeezeplay 7.6.2 installation, we have to edit usr/share/alsa/alsa.conf and set default device to "1" to use internal S/PDIF

I found this combined Toslink transmitter and RCA SPDIF socket.

http://www.ebay.co.uk/itm/360902397268

However, reading the info regarding the SPDIF I guess the additional components would have to be incorporated outside the joggler in order to use this socket.
I will see if the unit can be opened although I doubt there's room to modify and incorporate the components in there.

I haven't received the unit yet, so I'll see whether I try to use as is, or perhaps just cut off the RCA part.

It may also be that the joggler doesn't allow the full unit to be used anyway.

If I use as is I'd use the toslink connector so might not get round to trying to make up a lead which incoporates the necessary resistors and capacitors although if necessary I think this would be simple to do.

Once set up with the toslink i'll see what output the spdif gives without the additional components.

I'd like to find somewhere less fiddly to get the SPDIF output from than the tiny pins on that surface mount chip.

Sooooooooooo......does anyone know if there's a TP (Test Point) that carries the SPDIF signal that can take a wire pushed through the hole and soldered? If not is there a service manual with schematics available for this device that anyone knows of?

... actually not too fiddly a soldering job ... Have done a few ... all working great, no casualties .... go on give it a go!

... I opened out the screw hole nearest the chip and installed a 'flying' cable ... van damme mic cable is perfect at around 3mm o/d

Nah; wish there was one available.

Here still doing the USB to sound device thing. I did salvage an old cable with a single S/PDIF port on it which was connected to a card slot thing from a very old computer just to give it a go with the Joggler.

Best physical way to check if its working is just to send HD sound out of the port and look at it glowing red. Don't look directly at the source of light; it can damage your eyes; so do a side view of it.

On the multimedia receiver I do see status of the optical port; sometimes though still remove the optical cable and look at it.

On a scale of one to a million, just how fiddly is this mod to do ? I have a fine-tip soldering gun but am not very experienced at this sort of thing. I fancy leaving a trailing cable through the casing rather than putting a socket on and/or losing a speaker. Would I be better off nicely asking someone else to do this ? Don't want to kill an otherwise-innocent Joggler...

Easy Peasy.

Read this and look at a way to mount the connector outside of the case. I have done this with other stuff (USB) and used the small vent holes in the back of the Joggler.

http://www.jogglerwiki.com/wiki/Internal_SPDIF_output

Relating to digital sound have only utilized the external USB sound devices (whatever was cheap to purchase).

I did purchase an Asus S/PDIF dual connector and have taken it apart for this endeavor. Found it on my workbench.

The Asus bracket had two S/PDIF connectors each with 3 pins to connector for motherboard.

The little S/PDIF plastic end has a screw to connect it to the bracket. I would be easy to use the screw to fasten the connector to the rear of the Joggler and pass the wires inside. A little glue plus the screw will fix it better in the back of the Joggler.

STAC9202 pinouts :

pin 7 : GND
pin 9 : +3.3V
pin 48 : SPDIF signal

The optical connector I have has three wires; left to right; white, black and red.

Guessing here that white is the SPDIF, black is ground and red is VDC.
Here is a picture. I just looked on Ebay and could not find the same bracket with the two S/PDIF connectors. I know that you can find these though. I think I paid $2 USD for the one I purchased.

The Toslink socket I used needs 5 volts though,as I'm pretty certain most of them do?

Yes pretty easy as others have said. I did an optical socket but in the position that the RCA gets installed in the wiki article. The pins you solder on to on the audio chip are a little bit small but overall pretty straight forward. One of the hardest steps was finding the edge of the serial number sticker to peel it off to get to the screws [WHITE SMILING FACE]

Oh if it helps here's mine

Edit: apparently I can successfully mod a joggler but can't even attach a photo, Doh, let's try again
