Why? because I enjoy empty conversation with white-knighting sociopaths.
Off to bed. I see second hand googling turned out OK afterall.

This will most likely work for you, and if the card doesn't support Linux (doubtful) you can return it?

Hello again Inspector Gag-less.There are literally hundreds of USB soundcards with digital input. Have you actually looked anywhere before asking here, or did you mistake this forum for google?
Still waiting.
The Sound Blaster Extigy has optical and coaxial inputs. I just googled and it seems that it can be made to work with Linux. I don't mess with Linux/programming so no help on how to. But these can be found cheaply on the used market. I think I paid $5 at a local thrift shop
That looks good, thanks for that.The Sound Blaster Extigy has optical and coaxial inputs. I just googled and it seems that it can be made to work with Linux.

diyink makes a multichannel USB card that can be configured for I2S input and or output.
Other than that many USB recording interfaces can accept SPDIF digital inputs, but those inputs are most likely going to be resampled via ASRC. In that case they would not be 'bit-perfect' inputs.

The only one that I remember (because I own one) is the M-Audio Fast Track Pro. It has coaxial out and in. I've seen plenty with coax or toslink OUT, but coaxial input is rare. Hundreds? I haven't seen them. There might be a few in the pro market, and above the budget stated here.
BTW, it is bit perfect, I tested it.
I did own one of those little eBay specials that Kodabmx linked to. It's was just "OK". Don't remember ever using the Toslink input.

That's the thing with digital in on a sound card... even cheap crap usually works fine 😛
FWIW: I'm using this now with the DEQ2496 I bought from Pano because it was the only solution I've found. Even then, ALSA doesn't fully support it (I can't get 24 bit to work, 16 or 32 only)

I've seen you say this a few times but it does not match my experience. What interfaces have undefeatable ASRCs? Majority of the ones I've dealt with (admittedly all consumer/prosumer stuff) do not have ASRCs and if they do they are optional. To be honest I wish more had ASRCs to simplify clocking with multiple sources.
MOTU Ultralite Mk5: SPDIF input, TOSLINK/ADAT input, no ASRC
Focusrite 18i20 2nd gen: SPDIF input, ADAT input, no ASRC
Okto dac8 pro: AES input, no ASRC
RME Fireface 800: SPDIF input, TOSLINK/ADAT input, no ASRC
miniDSP USBstreamer: TOSLINK/ADAT input, no ASRC
miniDSP MCHstreamer: TOSLINK/ADAT input, no ASRC
Apogee Ensemble (Firewire): SPDIF input, TOSLINK/ADAT input, optional SRC
MOTU 896: AES input, ADAT input, optional SRC on AES input only

I don't understand at all ASRC but I think it may not be necessary if I am putting SPDIF digital in and wanting digital output to USB. Seems there does not need to be much sampling.diyink makes a multichannel USB card that can be configured for I2S input and or output.

Automatic sampling rate convertion... Usually handled by the OS anyway.
It is actually asynchronous sample rate conversion, meaning that the incoming digital stream is reclocked using the internal clock of the interface.
Most interfaces have a variety of clocking options (internal, SPDIF, ADAT, AES, word clock) and if you do not have an ASRC and are using a digital input you need to clock the interface from your digital input unless you have your source slaved to the interface. Without selecting the appropriate clock source you will have dropouts.
If you have an ASRC in the interface you can set the interface clock to internal and it will handle any digital source without issue.
Below is a great thread explaining the theory behind ASRC.

https://www.sweetwater.com/c695--USB_Audio_Interfaces hope this helps.Hello
Does anyone know of a usb sound card that has a digital input. It also needs to be linux compatible and not very expensive.
Help appreciated.
Thanks

Thanks 1883, they look very interesting.https://www.sweetwater.com/c695--USB_Audio_Interfaces hope this helps.
I have just ordered one of these

Hope it works but if not will look at yours.
Thanks

I got my HiFime UR23 and it,s brilliant, it appears as an input device in Audacity so no problem to record.
I have it plugged into the DAC on my Hifi system. It gives digital output for the UR23 and so to USB in to Audacity.
