no gnome sound events, mtrr overlaps, acpi sleep resume

Hi, sorry for the long title (at least its more descriptive than "3 problems, please help" ;))

Anyway...

Firstly I can't hear any gnome sound events, on the gnome sound applet from desktop preferences the gnome sound server is enabled and use sounds for events is checked. Also I have checked that the audio files exist. When I click to play a sound event I don't hear anything at all and have maxed the master volumes and checked they are not muted. Aside from this the rest of my sound system is working (CD/DVD, MIDI, MP3 etc) and the the sound event .wav's play fine using xmms or any other media player.

OK second, when I check 'dmesg | tail' I'm getting mtrr overlaps:

Code:

ISOFS: changing to secondary root

So I done some googling and found out that if use 'lspci -v' (snipped output follows)

Code:

0000:00:02.0 VGA compatible controller: Intel Corp. 82852/855GM Integrated Graphics Device (rev 02) (prog-if 00 [VGA])

        Subsystem: Sony Corporation: Unknown device 8192

        Flags: bus master, fast devsel, latency 0, IRQ 9

        Memory at e8000000 (32-bit, prefetchable) [size=128M]

        Memory at e0000000 (32-bit, non-prefetchable) [size=512K]

        I/O ports at 1800 [size=8]

        Capabilities: <available only to root>



0000:00:02.1 Display controller: Intel Corp. 82852/855GM Integrated Graphics Device (rev 02)

        Subsystem: Sony Corporation: Unknown device 8192

        Flags: fast devsel

        Memory at f0000000 (32-bit, prefetchable) [size=128M]

        Memory at e0080000 (32-bit, non-prefetchable) [size=512K]

        Capabilities: <available only to root>

I should add a 'vram:128' parameter to my kernel's menu.lst entry and that should fix the overlap. Rebooted and still dmesg reports the mtrr overlap :(

Thirdly, I'm having problems resuming from acpi sleep. I'm using the following shell script:

Code:

#!/bin/bash



#sync the disks.

sync && sync && sync



#Change the screen to VT1 (text mode)

/usr/bin/chvt 1



#perform the actual "go-to-sleep" function.

echo "mem" > /sys/power/state



#Pause a second or two to let us sleep.

sleep 2

Which seems to work great (LCD turns off and standby LED goes on), but I'm stumped as how to wake up the machine and get back my X session. When I press any keyboard key it wakes from sleep mode (can hear the HDD spin up etc), but the LCD doesn't turn back on so I don't know whats going on. I've tried pressing CTRL + ALT + F1 that should get me back to my bash shell but that does nothing.

If anyone could help me with any of these annoyances it would be great :)

I have just solved the sound problems I had in slackware after a recent kernel upgrade. I also had no sound in Dropline Gnome EVER, even though xmms etc worked.

I compiled the latest alsa drivers, libs, utilities and OSS compatible libraries, and it all fell into place. this pdf helped a lot too. Hope that helps in some way!

*Forgot about this thread*

Thanks for the suggestion, but my ALSA setup is 'sound' excuse the pun. This is a problem with Gnome and not ALSA. It turns out that Gnome doesn't install everything it needs to play gnome-sound events.

With the help of the following webpages I was able to get Gnome sound events working:

Quote:

1) Install esound, esound-clients, gnome-audio, gstreamer-plugins and libesd-alsa0
2) #killall esd
3) #gedit /etc/esound/esd.conf

Find this section:

Code:

auto_spawn=0

spawn_options=-terminate -nobeeps -as 5

Replace with the following lines:

Code:

auto_spawn=1

spawn_options=-terminate -nobeeps -as 2 -d default

Save the edited file

4) gedit /etc/asound.conf

Insert the following lines into the new file:

Code:

pcm.card0 {

type hw

card 0

}



pcm.!default {

type plug

slave.pcm "dmixer"

}



pcm.dmixer {

type dmix

ipc_key 1025

slave {

pcm "hw:0,0"

period_time 0

period_size 2048

buffer_size 32768

bindings {

1 1

}

}

Save the edited file

5) #ln -fs /usr/lib/libesd.so.0 /usr/lib/libesd.so.1

6) Open up Gnome sound preference from the panel:
- Enable sound server startup: Checked
- Sounds for events: Checked

7) Reboot computer

As for the other problems :\

Well the mtrr overlaps don't seem to be affecting the system performance or stability in anyway. I've read that its the vesafb that is the problem. I tried adding nomtrr to my menu.lst but that did nothing. The only other fix I can see is recompiling my kernel to use the intelfb (I chose vesafb as recommended for bootsplash, which I'm using). Anyway I don't play any FPSs so getting the most out of my gfx card isn't that much of an issue.

The ability to sleep/suspend would be useful, but startup/shutdown doesn't take all that long on my machine which compensates for this (at present) lost functionality.
