Hi - I’m a new member from Leadville, Colorado, living at 10,000 feet of altitude. My favorite current hobby is multichannel audio of all flavors, which I particularly enjoy over headphones using a binaural processor (Smyth Realiser A16).
I’ve been working on two projects lately. The first is using an RPI5 + DAC8x + ADC8x (HiFiBerry hats) to convert the 6-channel analog output from my Surround Master V3 to HDMI (my AVR does not have analog inputs). This has been very successful, and I’ll probably go on to explore using CamillaDSP in addition. I’m also using it via Audacity as a replacement for my old Korg D888 8-channel analog recorder.
The second project is exploring ways of extracting HBR audio streams from HDMI. I have an old Unigraf frame grabber which works, but I need to write some code for it to work better. I have a Chinese HDMI input to I2S x4 board that should work but I haven’t had a chance of hooking up my logic analyzer to the 4 I2S outputs yet. I have a Rock Pi 5b that has the necessary hardware, but I need to wait for the mainstream kernel to support multichannel audio in from the HDMI RX (6.15-RC1 is just out and may do the trick; the current kernel driver only supports 2-channel). Finally, I have an HDMI extender over 10 gigE TCP/IP with a managed 10gigE switch that will allow WireShark or similar snooping.
