Feel free to upload your code so we can have a look at it.

I got the code working and can receive IR characters with both the Sony and Rosewill (RC6) remote controls. If I can find a couple of the other remote controls that are supposed to be supported, I'll test them as well. Since it works with SONY and RC6, I feel the rest of the remotes will work as well.

Once I figure out how to strip the toggle bit from the RC6, get it decoding properly, and clean up all the patches I'll post the code.

Although it might be best to wait until I get the proper 20X4 display and revert to that code instead of the current 16X4 display code.

I have to go cut the lawn before it rains right now.

Volume up, Volume down, Mute ( was Dim) work, but once a button is pushed the system acts as if the button is held down and never let up.

Pressing another unused key stops it.

code attached has one untested change in it to disable and re-enable the interrupt.

Code is now functioning with a Sony TV Remote (no part number I could find) and the Rosewill RHRC-11001 (RH-6) remote controls.

It probably needs some clean up to remove test code, but it does seem to work for all three keys. I used the up and down keys along with the Mute key (I changed the code to reflect the US convention of Mute to silence or lower the volume. Most devices I've seen do this by 20dB so one can tell the sound is still on but it is low enough not to interfere with a telephone conversation, etc.

I changed the mute level to correspond to this as well.

I'll post the code again when I finish cleaning it up.

Code now works with the following changes:

- Changed display to 16 X 4
- Removed Apple remote code
- added Sherriff's code for multiple remotes
- added decode for RC6
- added decode for SONY (not sure which one as there are many)
- added placeholder for Apple
- Reorganized code to put all IR Remote operations under one case statement
- Duplicated Button code for filter switch and added to case statement for remote filter operaton
- changed dim to mute and add mute value to volume value during mute (ie. mute by 30dB) so it mutes by a specified amount instead of an absolute amount.
- added Beta to code revision. now B 00.01.06

I'd still like to allow SW clip limit, and may get to it later.

I've attached Sherriff's IR code as well as my code.

Does anyone have the SPDIF input working?

I've tried both my soundcard output and the output from a CDRom drive that I transformer coupled with resistors in an impedance matching network and neither work with this card.

I tried both sources with another DAC board I have (CM102S/CS8416/CS4398) and both worked with it so I don't think it is my source that is the issue.

I took the WM8804 receiver off ribbon cables, attached sockets on the bottom and plugged it directly on the pins on the DAC board. SPDIF still refuses to work.

I've got a set of boards, but don't have the patients or time to mount these smd parts on it.

Anyone want the boards? or put it together for me?
