D00M³ runs fine but NO SOUND (using ALSA with OSS emulation)

[sLiCeR]

Okay,

so this is my Problem:

Code: Select all

=======================================================================

during DOOM 3 initialization...
WARNING: mmap 32768 bytes on device /dev/dsp failed: Input/output error

WARNING: sound subsystem disabled

2 warnings

=======================================================================

Any ideas?!?!

First, make sure /dev/dsp exists and (if it's a symbolic link) points to a /dev entry that actually exists. After that, check whether you're in the audio group (otherwise you won't be able to access /dev/dsp).

I had the same error with my AsRock K7S8X-E onboard sound (SiS748). I haven't found a solution other than to switch to my old soundblaster 128. Now it works. Maybe Doom is a little picky about soundcards.

it exists and all other audio apps work (also tested OSS output with XMMS, works fine)

strange problem

[sLiCeR]

Could it be its a problem with my nforce2 u400 onboard-chip?

There's already a similar thread in this forum:

I've had the same problem. Try the following steps:

Make sure you have alsa correctly installed (with alsa-utils and alsa-oss) according the gentoo alsa guide (viewable under docs @ www.gentoo.org)

After that, try the "old" id game trick:

Code: Select all

# echo "doom.x86 0 0 direct" > /proc/asound/card0/pcm0p/oss

if this doesn't yet help, try furthermore:

Code: Select all

#modprobe snd_via82xx dxs_support=3 

After that, on my side, the error changed to the one complained in the thread remarked above:

Code: Select all

--- Common Initialization Complete ---
------------- Warnings ---------------
during DOOM 3 initialization...
WARNING: ioctl SNDCTL_DSP_SPEED failed to get the requested frequency 44100, got 44101

WARNING: sound subsystem disabled 

Finally for my via82xx, i've solved it:
Set in ~/.doom3/base/DoomConfig.cfg
the following Line to:

Code: Select all

seta s_dsp "/dev/dsp1"

hope this helps

Okay, Im stuck he...

[sLiCeR]

Without the dsp1 thing (which obviously must go wrong) i get this now, can I enforce my DSP to make 44100 instead 48000 ?

Code: Select all

Okay so i tried the HEX-Trick after i got the above lines:

Code: Select all

- "hexedit doom.x86"
- go to the byte to modify by typing "Ctrl-G" and entering the address: 001BED1B
- modifiy the "74" under the cursor to "EB".
- save (Ctrl-S) and quit (Ctrl-Q) 

Thats all, now I have sound, great trick

Holy flaming penguin poop.

Never in my life have I seen such an obscure fix as this little "hex" fix.

I was just shaking my head while I did it saying to myself "I am gonna #$%^ myself if this works."

Well ladies and gents, I have crapped myself. It worked. How in the bloody hell did someone figure THAT one out? And THANK you.

I have the same problem:

Code: Select all

Guess it was really stupid to compile snd_via82xx into the kernel, since I can't try that "dxs_support=3" parameter. Guess I'll have to recompile tomorrow, or any other idea?
