      Update: I tried to simply pull audio out of my SCART switch box and thus bypass the audio from the OSSC, and I realized that as long as the OSSC is hooked up to the SCART switch box, even if the OSSC is unplugged from power, causes the left audio to be extremely low. As soon as I unhook the OSSC from the SCART switch, sound output goes back to normal. What could be going on with the OSSC that suppresses the left audio even when turned off? Of course, connecting a console directly to the OSSC’s SCART connector also results in low/no audio from the left channel (plus noise).

      After a few tests of the OSSC that I received last week, today I noticed that the left channel started producing noise, and eventually stopped outputting any sound through the HDMI output. Through the stereo jack output I can faintly hear some sound on the left channel (even when the OSSC is unplugged! I’m guessing it acts as a passive switch). The same unit had also given me a few problems with sync briefly dropping with some consoles since I received it, so perhaps this unit was defective from the start?

      I already sent a message through the Contact Us form, but I figured I’d try to ask for suggestions here also.

        I’m concluding now that something must be wrong with the SCART connector. When the OSSC is powered off and a SCART cable is connected to it the left channel is suppressed, and when the OSSC is powered on it produces loud static noise on the left channel.

          Probably won’t help, but maybe make sure that that AV1-breakout/AV2-input switch near the HDMI connector is fully one way or the other.

            Thanks for that suggestion, I tried making sure that little switch was fully one way or the other but it did not make any difference.

            I’m sure I’ll be getting a replacement unit, but I’m still very curious about what could cause this problem, and in particular how the OSSC can still affect the sound just by being hooked up even without power.

              It’s possible it’s just a bad solder joint; it happens now and again. BuckoA51 can probably give you a better idea of what’s actually going wrong.

              If you bought yours from VGP, I believe you can initiate a return/repair process with the Contact Us form linked in the main navigation.
