I recently bought the HT-RT4 5.1 sound system and hooked it up to my PC via an audio jack cable (my PC doesn't have optical and doesn't have HDMI ARC). The sound seemed fine initially however I recently noticed that there was a delay in sound in comparisson to what I was seeing on screen, I would say around 50-100ms. That caused lyp sync issues.
I changed the cable to a new one and that seemed to solve the issue, however the delay eventually came back, I don't know how quickly but I noticed it eventually. Before and after changing the cable I have done everything I can from the PC side, re-configured speakers, updated drivers, tried differenr devices, nothing seemed to be a clear fix. I've reset the speakrs as well.
Does anyone know what could be causing the issue? I never had issues with analog speakers before, so the fact that it's happening, and the fact that the issue comes and goes seems very strange to me.
Ideally I would like to find a fix and keep using the analog connection to leave the optical port free for my PS4. And just to be aware my monitor doesn't have its own optical or HMI Arc connections so I can't hook the speakers directly to it (except for analog which also had the delay issue).
Many thanks for any insight.
