Sound Error Mac Classic (Video in)

You can identify the error that it has, it tries to communicate but I don't know if it is a Rom error or what it indicates.

Nothing good for sure, can be anything but the Classic will display an error code if it's able to go further enough in the process.

I think it's something from the cut tracks but after 5 hours I haven't found anything, I'm afraid the Rom is dead but it's weird it does the same thing to me with two Roms and I don't think it's both dead. I have ordered a new board and will solder everything there again

I think it is just glitching, not trying to communicate. Mac Classic era macintoshes use a serial port for debug, not beeps. Other than the sad mac chime.

That makes me think it is trying to chime, so your ROM is possibly OK and I'd start by checking the RAM, where the audio buffer is.

"I think my ROM is dead, it's not going past that and it's not making any noise anymore, it's a shame. I'm posting to see if anyone is selling a ROM so I can rule out the issue."
