TinyTOSLINK (digital audio output) now for B+, too

[BenjaminKe]

Hi,

yes it is possible to use both, because the output of the sound IC is connected to the optical output and the "normal" digital output.

I will write you a PM.

Best Regards
Benjamin

Have any left? what would be the price to Australia?

Thanks

Hello
Sory for my english, I like to buy your tinytoslink. Can you sell it and send to germany or poland? What will be the price? Or can you send me how to make this board and what elements I need.

[dab654]

Hello!

I like it, will send you a PM next!

[SavageThor]

Might be late to the party but I got to try to get one. Do you have any left?

[BenjaminKe]

Hi All,

yes I still have some left.

I will write you all a PM.

Best Regards
Benjamin

Hi Benjamin,

I was browsing the Internet in order to find a way to get TOSLINK on the RPI2 and I've found your topic. Can you tell me more about this device by PM (Shipping Price, Price, is it available for Pi2). I live in France.

Thanks a lot for your awesome work !

[BenjaminKe]

Hi Midask,

yes it is for the RPi2 but should also work for others which have the same layout/pinout (B+, RPi3).
For the RPi3 you need a different (smaller) optical connector, because of the WLAN antenna which is mounted there.

I will send you a PM.

Best Regards
Benjamin

Hi All,

Did anyone try to use BenjaminKe's or [IDC]Dragon's board on Raspberry Pi 2 B with Raspbian Jessie? I'm having trouble with getting it to work. I don't want to use OpenELEC nor any other distro - I prefer to make it working on clean Raspbian.

I added HiFi Berry to device tree and disabled default audio card in /boot/config.txt:

#dtparam=audio=on
dtoverlay=hifiberry-digi

I see HiFi Berry in aplay:

pi@raspberrypi:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_digi], device 0: HifiBerry Digi HiFi wm8804-spdif-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0

When I play flac file with mplayer over hdmi it is ok. But when I disable on-board sound and load HiFi Berry mplayer plays file but my AMP does not see digital signal on input. I don't have oscilloscope at home to check if anything is transmitted. But anyway I think it migth be raspbian configuration issue. dmesg show this output:

I'm not sure if there are issues here. Does last line mean that wm8804 is operational?

Anyone have an idea how to debug it further?

Hi Benjamin,

I'm wondering, do you still have some parts left? Unfortunately I also came across this thread just now. I highly appreciate your efforts. Kudos to Jörg and all the others involved!

Cheers

[zydawn]

hi jorg are you still selling these toslink hats
just purchased a pi 3

[paradiza]

Hi Jörg,

So far I've published boards and schematics of all my creations, but with TinyTOSLINK I was hesitant, since there is Hifiberry Digi.
[...]
Now that the hardware design is kind of public, I'm reconsidering.

Just curious, what's the status of your reconsiderations? While the alternative designs of Benjamin et al are very nice in their own right, your concept still seems to be the most elegant solution so far. Thus I wonder whether you might eventually publish the details? I read your opinion on DIY-etching but some of us might have access to suitable facilities to get it done right. I'd love to give it a shot.

Thanks in advance!

Hi BenjaminKe

Thanks for your awesome work. I have been looking for nice digital audio output for a long time.
If you have any left I would like to buy one.
Pls sent me pm or contact me via e-mail: zadarr@gmail.com

Thanks
BR

Hi Dalter,

yes I still have some left - I wrote you an email.

Best Regards

[dmorts]

Hi,

I'm really interested in a TOSLink input. Would this be possible to produce?

Thanks

[gsi095]

Hi Benjamin,

I received the board today, that's quick to Australia.

I got to wondering if it would also take an optical input from another device and then out to speakers using a USB DAC?

the board is really quite a quality piece of equipment.

Thanks
Dave

[BenjaminKe]

dmorts:
I wrote you a PM.

Dave:
The WM8804 chip has an input and and output.
So theoretically it is possible to use it also as input and capture a optical signal (there is a not assembled pinhead connector with 2 pins on the PCB - with a 0 ohm resistor you can connect one of these 2 pins to the input and connect your optical receiver here).
But I don't know if there is some support from the HifiBerry software for something.

Best Regards
Benjamin

[Sandor]

Hi Benjamin, if at all possible I'd love to take one or two of these off your hands as well Board+parts would be fine, I don't mind soldering a little from time to time. Thanks!

EDIT: And a big thank you to Jörg too of course

[BenjaminKe]

Hi Sandor,

sure - you got a PM.

Best Regards
Benjamin

Hi ! I've just received the device and I have the same issue. The device is working on OpenELEC but not on Raspbian, same problem !

[NikkAlek]

Hi Ben,
I'd love to pick one of these up for my Pi3. What would be the cost with shipping to get one to me in Pennsylvania, USA?

[aTTilaz]

Hi Ben,

I would also love one of these, possible to get one posted to Australia?

Thanks

[antorsae]

Hi Ben,

Im interested in your board to be used as a TOSLINK input. According to this: https://support.hifiberry.com/hc/en-us/ ... ital-input it may work.

Can you PM me if you have boards left?

Thanks!

[maroi]

Hi Ben,
i'm also interested in a board for the rasperry Pi 3.
Could you please make me an offer with shipping to austria?

regards

[Skicraft]

Hi Ben,

I am also interested in creating a TOSLINK input for my Pi 3, do you have any left ?
