So I've been enjoying the Atomiswave Dreamcast ports using the serial port with an SD adapter. It works great but I recently updated my DCHDMI firmware to 4.7 and I've been experiencing audio dropouts about every 30 seconds or so. It basically drops out and then comes back after a second. Anyone else have a DCHDMI and have the same problem. I'm using the relaxed firmware with some new HQ2x filter so maybe that is it?
