Omnibook 4150B - enabling sound device Maestro

[Malycha]

Hi!
After installing SuSE 7.3 on my HP Omnibook 4150B I was not able to activate the sound device (ES1978 Maestro 2E). During the test-procedure the notebook always hangs and only a hard reset (power-off, keybord also hangs!) helps. I think it is an interrupt problem.

Is there any possibility to change the interrupt or to activate the device?

Hello,

Personally I have been using an OmniBook 4150 (not 4150B) for 3 years.

The audio device is compatible with Windows Sound System. I use the "ad1848" driver, with io=0x530, irq=5, dma=1, dma2=0.

In /etc/modules.conf :

alias sound-slot-0 ad1848
post-install ad1848 modprobe "-k" opl3
options ad1848 io=0x530 irq=5 dma=1 dma2=0
options opl3 io=0x388

Don't forget to type "depmod -a" after changing /etc/modules.conf.

Good luck.

Hello!

I found a possibility yesterdays evening: You must not use the alsa-sound-module. There is a problem with the maestro-chip and alsa. If you change the

/etc/modules.conf

to the following

alias char-major-14 maestro
# alias sound off
# alias midi off

and disable all entries about alsa the sound will work! Then the system uses the kernel-modules for playing sounds an there are no problems with interuppts!
