Dell poweredge 2300

the right channel speaker does not work any more

Go into the RAID setup during bootup (not always in the BIOS), but will post somewhere on startup (should say SCSI/SAS Controller card press CTRL + M to enter setup) or similar.

When in the raid setup check to see the status of the drive(s).

Was the machine running and it's just happened etc or are these machines you have obtained and are plain not working?

It probably is trying to tell you that it is overheating.
Check that the fan(s) on top of the CPU(s) is/are working.

mine did the same thing today , i just bought these new 2 weeks ago . the black prong speaker works in both ports ..
the yellow prong speaker is the one with the malfunction .
it works sometimes but when i turn up the volume louder it dies out .

Make sure the PAN control is centered in your mixer control panel.

It can be the speaker has a short in the wire. I had several speakers have a little short in wire. They would work only if i moved wire a certain way or play with it. Had to open up one to find the short and fix it.

Check lsusb and see the list if u can find the root in the list

so what is the question?

I have a older poweredge 2300 i get the following message run program setup.

Unfortunately, Logitech doesn't sell the wired remote controller separately. And that seems to be infamous for going out.
What worked for me (with no sound and no blue light on the remote connector) was to plug a set of earphones into the earphone port. As soon as I did that, the blue light came on and the sound was restored, even after removing the earphones. Someone else said both speakers worked properly while they had the earphones in, but not otherwise.
