I have an ESS ES1688 AudioDrive (rev 11) (3.1) and still have that problem,
despite wiping the kernel tree and extracting a new fresh tree in its stead.

The oddity is the reported MPU401 IRQ when I cat /dev/sndstat :
Installed drivers:
Type 1: OPL-2/OPL-3 FM
Type 2: Sound Blaster
Type 7: SB MPU-401

Card config:
Sound Blaster at 0x220 irq 5 drq 1,5
(SB MPU-401 at 0x330 irq 5 drq 0)
OPL-2/OPL-3 FM at 0x388 drq 0

Audio devices:
0: ESS ES1688 AudioDrive (rev 11)

Synth devices:
0: Yamaha OPL-3

Midi devices:

0: System clock

0: Sound Blaster

I specified IRQ 2 for the MPU and I suspect that this causes this PnP card
to freeze up when booting into MS-Dog (?)

<shrug> It would be nice to be able to soft boot, but I can live with it.

The other oddity is the kernel reporting on bootup :
Sound initialization started
<ESS ES1688 AudioDrive (rev 11) (3.1)> at 0x220 irq 5 dma 1,5
<Yamaha OPL3 FM> at 0x388
Sound initialization complete

So, where's the MPU device that /dev/sndstat reports ?

Hannu ?

While I'm at it, is ESS somewhere on the 'Net where I can get the latest
drivers released for this card ?
