NEC TXi w/ MDK 9.1 no sound

The sound card was detected correctly (same as in winme) ES1988 Allegro-1, driver is maestro3. But it won't produce any sound.
Here are some info:

alias eth0 eepro100
alias sound-slot-0 maestro3

[dummy@localhost dummy]$ /sbin/chkconfig --list alsa
alsa 0:close 1:close 2pen 3pen 4pen 5pen 6:close

I'd tried to adjusted all parameters in aumix to max, no luck.

Any help?

turn the amp on

Hi I just got mine working. The external amp is disabled by default. It is connected to GPIO Pin 3. I know this cause I worked for NEC and I have the schematics and specs.

GPIO= BIT3 = 0x0008

As root do this.

inw 0x1468

This shows GPIO 3 is set to input mode. Change it to output mode.
[root@jeff root]# outw 0x1468 0x0119

Unmask the gpio write access.
[root@jeff root]# inw 0x1464
[root@jeff root]# outw 0x1464 0xfff7


Now read the GPIO register.
[root@jeff root]# inw 0x1460

0xF6E7 + 0x8 = 0xF6EF

Turn on the amp
[root@jeff root]# outw 0x1460 0xf6ef

You've got sound, desuka?

You could probably assume the read values will be the same and then set-up a script to run at startup (/etc/rc.d/rc.local)

Here's an even cleaner solution for those who might care. The maestro driver has an option that better than the above hack. The sound is on much earlier (pre X11) and requires no user intervention.


alias sound-slot-0 maestro3
options maestro3 gpio_pin=3

Mandrake has HUGE problems with soundcards on laptops in my experience. I have had similar issues with mine, though different card. One simple thing to remember is that by default all channels are muted. Good test if your soundcard is working is to run aumix, if it opens with sliders your soundcard is probably working.

With me I had to give up on Mandrake for use on my laptop. 9.1 kept detcting my card correctly, but the new alsa drivers don't work for my card (crappy es1371). I have always been able to config it manually, but whenever 9.1 boots, it detects my soundcard again and loads the alsa drivers automatically which do not work. I litterally would have to remove the drivers then manually load the drivers every time if I wanted sound. Wouldn't matter what I tried to fix I couldn't get it working. I run Red Hat right now on it and It didn't have any problems running my sound card and I had to do no manual config at all. Sound is one of Mandrake's weak points.
