I am having a strange issue with my RFM. I made a post about it in the tech: modern games and haven’t had any traction. So I thought I would post here.

Every time I turn my RFM on and wait for it to boot, the sound will only work if I unplug and plug back in the audio cable on the front of the cpu in the back box. Video below.

I put a new CRT in it and things worked fine. During the boot sequence you could hear the speaker “pop” when the amp powered up and then the “bong” sound when the sound was initiated during the boot/test sequence.

A few days ago I noticed that when it finished booting there was no pop, bong, or sound after the initial test sequence.

The first thing I did was unplug the speaker connector from the front of the cpu and then plug it back it. The sound started working as soon as it was plugged back in.

-This only happens with a hard power cycle of the machine, a restart in the service menu will not cause the machine to lose sound.

-The LED on the front of the audio amp is solid-on the entire time.

-The light on the prism card is on as well.

-I have reseated the connecting cable between the prism and amp.

My thought is that the amp is not initializing the speakers during the boot sequence?

Any thoughts? Many thanks in advance for any information.
