iSub subwoofer 'disconnects' after sleep mode

Hello, one more problem for the audience to solve...

Recently upgraded my 15" iMac flatpanel to OSX.2.6 from OS 9.2
Things seem to be OK, except for occasional kernel panics and the
spinning beach ball of death.

Often, though, when coming out of sleep mode (mostly after Mac sleeps
for more than 2-3 hours) the iSub subwoofer quits working. It no longer
shows up in the sound control panel, and I have to reach back in the
mess of cables, unplug the iSub power cable & USB connector, then
reattach to get it to work again.

I've had a few issues with sound on this Mac. Under OS 9, I would
periodically get messages on bootup that "the device plugged into
speaker jack could not be recognized" and have to unplug & replug the
Apple Pro speakers for the message to go away. Also, the total sound
volume under OSX seems much softer than OS 9. I've got to have the
sound slider bar up halfway to get the same decibel level that I got
under OS 9 with the slider bar set to 1/3.

Any ideas? I'd like to think that OSX does not cause partial deafness,
and sleeping causes iSubs to take a vacation.

Thanks,

El Capitan

I don't have the iSub but others did report problems with iSub (USB
connection) having this bug. I know of no solution. I remember most got
by with just unplugging and plugging USB back in the iSub to make it
work. I think it was in both OS9.x and OSX. Not sure if later versions
of OSX cured this bug or not. The bug did have to do with sleep function.

I also had the Pro speakers connection dialog problem at boot on
occasion, but curiously the Apple Pro Speakers always worked despite the
odd intermitant occasional warning on boot up with actually having to
disconnect the Pro speakers.

Good Luck
