As per the topic, am I wondering if it would be possible to do something like bypass the DAC in, for instance, an X5, and create an optical out? Has anyone ever done something like that before? I tried searching, but no luck.
For the optical transmitter, Toshiba TOTX177 part number 1225771 from Farnell will do the trick assuming the piece of kit you're on about is 5V. Try the TOTX147 if it's 3.3V.
You need to find the SPDIF signal inside the X5 (if there is one) to send to this transmitter. Then the only other connections it needs are +5V and ground with a decent capacitor between them.
If there is no SPDIF inside the X5 (I have no idea) you will need an SPDIF transceiver. Try the Wolfson WM8804, it will convert the I2S or 16b RJ data or whatever it is into SPDIF and you can then fire it at the optical transmitter and the job's a good un.
Edit: Just dawned on me that the X5 is perhaps a portable device and that's why people have said it will be tricky, if it is, I agree!
right. if you have s/pdif, converting to optical is a walk in the park. But why bother?

AudioCubes2 declined to cancel my order, then lied to me and told me it had already shipped a full business day before the date on the shipping label.
Would it be possible to create an Optical Out?
