Hi, I just got my OSSC and been trying it this evening. Everything seems to work OK minus the sound. My setup is OSSC 1.6 firmware 0.82a, conected to Tendak HDMI to VGA converter to a VGA CRT and outputting audio from the Tendak to monitor speakers. If I connect the OSSC to a LCD TV direct by HDMI sound is OK in all inputs, but when I use the Tendak adapter to the CRT then I have only but crackling sound, changed all options in OSSC without any success, even tried to downgrade to 0.78a firmware but same result. The Tendak adapter works OK if I connect to a NES Mini Classic, sound is OK then, so must be the way OSSC encodes the sound to HDMI. Tried different cables, and changing AV1/AV2 audio switch position (AVI audio output works too).
Anyone with a similar setup? What else can I try?
