Hello,

I recently acquired a used 600E (2645-4AU) which came with WinME
on the disk, and I swear, the audio was working when I first booted
it to make sure it was OK.

After this, I promptly wiped the disk and installed my OS of choice,
FreeBSD. I managed to get the sound probed and can send stuff to the
audio device, and it pretends to play, but I get no sound output, as
if the mute (Fn-backspace) was on although I press the volume-up
multiple times to make sure the volume is up.

I've since broken down, reinstalled both Win98 and WinME with
exactly the same results: the CS4610/11 audio device is detected,
configured, and I can ``play'' audio but I get no output from
the speakers or headphone port. No dsp, no PC-speaker-type beeps,
no CD audio, nothing at all. It's as if the hardware mute is stuck.

I've fiddled with the DOS-mode PS2 utility with no luck, and now
my best guess is that it's an undocumented conflict of some sort.

I've tried both re-initializing from the easy-config as well as
re-flashing the BIOS but it keeps the device settings the same.
Is there any way (short of disassembling and removing the backup
battery, I guess) of reseting the PS2 defaults?

Anyone have any other suggestions?

Thanks!
