I'm hoping someone can help me figure out what I'm doing wrong because I've been troubleshooting this for hours.

My equipment:

• TV: LG 60PV250 Plasma
• Receiver: KLH R3100 Stereo Receiver
• Console: PlayStation 5
• DAC: PROZOR 192kHz Digital-to-Analog Audio Converter (Optical/Toslink to RCA + 3.5mm)

What I'm trying to accomplish:

I simply want to play my PS5 through my old stereo receiver and two passive speakers.

Current setup:

PS5 → HDMI → LG 60PV250 → Optical (Toslink) → PROZOR DAC → RCA (or 3.5mm-to-RCA) → TV input on the KLH R3100 → Speaker wire → Two passive speakers

What I've tried:

• Verified the optical cable is working (I can see the red light coming out of it).
• The PROZOR DAC powers on normally.
• I've tried both:
  • The DAC's RCA outputs.
  • The DAC's 3.5mm headphone output using a 3.5mm-to-RCA cable.
• The receiver is set to the TV input.
• I cannot find an option in the TVs menu that allows me to change the audio output despite the manual showing it.
• The speakers are wired directly to the receiver.

What's happening:

I can hear the PS5 audio very, very faintly, but only from the right speaker (the speaker physically on the right side of the TV). The left speaker produces nothing.

The volume knob on the receiver doesn't seem to make much difference because the sound stays extremely faint.

I feel like I'm incredibly close since audio is making it all the way through the system, but I can't figure out why it's only faint and only on one side.

Any troubleshooting ideas would be greatly appreciated.
