alsa and intel8x0-sndchip onboard AC97Audio troubles

well.. im experiencing heavy troubles...but couldnt yet figure out *what* is really causing the trouble...

the trouble is that only ONE app at a time is able to aquire the sound-device
(i already tried the wiki-page about configuring alsa for HW or SW mixer ... that didn't help)

and googeling for hours didn't result in any hint...

 
hwd -e

8086    24d5    "snd-intel8x0"  "Intel Corp.|82801EB AC'97 Audio"

ideas?

http://wiki2.archlinux.org/index.php/Al … 0at%20once

are you sure you have tried everything there? if you had a problem with any, ask.

if that doesnt do it, bad luck

Re: alsa and intel8x0-sndchip onboard AC97Audio troubles

ah Thx!

i missed that wiki-page... didnt come up when i searched wiki for alsa  :oops:

ATM im at work... but i'll give that a shot asap and report ...

sidecomment|whining
id say the sound-driver itself should handle the SW-mixing if the HW doesn't do it  :evil:
only as a option it should be possible to deactivate it and use the mixer of his own desire  :?

Re: alsa and intel8x0-sndchip onboard AC97Audio troubles

I would stick with alsa rather than those closed source drivers, i have the same soundcard and have had the mixing working in the past, so i know its possible with alsa, its not working atm though.  ill probably try to get it working again tomorrow, if i figure anything out ill let you know

Compile the sound modules in your kernel instead of having hundreds of dependent modules for that.

Re: alsa and intel8x0-sndchip onboard AC97Audio troubles

I'm using esd to play multiple sounds at once. Works fine with apps that can explicitly select ESD to output sound (xmms, bmp, gaim). But rhythmbox for example, complains it can't complains that /dev/dsp(OSS?) is already in use by another program. How do I get sound in rhythmbox, my favorite music player?

Btw if I stop ESD and play a sound with rhythmbox, it works just fine. I have a Acer Travelmate 4501LCi with a Intel 855GM (snd_intel8x0)

I use the closed source drivers. Alsa's dmix doesnt handle OSS apps, so when one of them hits the soundcard, its locked up again.

Re: alsa and intel8x0-sndchip onboard AC97Audio troubles

well.. i solved my troubles...

the sollution ... ALSA just supports i8x0.. but i need ICH5 support which oss offers 

i got a preassembled box here..thats why i did never have a look at the exact HW.. till now... and what i saw there shoked me a bit...
my MOBO (P4TSP-D2 if somebody wants to google it) doesn't have a onboard-sound-chip as im used to it but uses the Intel Southbridge ICH5 and a freakin CODEC-chip - CMI9739A or CMI9761A - i don't know exactly (maybe i have a look later)

and that got wrongly identified by alsa and hwd
therefore i thought alsa and the module is OK.. until i had a look in the MOBO-spec and googeled and googeled and googeled..

waho.. that was a tricky one.. im feeling like 10 years back in time when you had to guess together with isapnp what you got in your box 

the funny thing was that i HAD sound.. (cuz both are AC97) ... just shot me down when i wanted multible apps to access the sounddevice...

hope this helps others who experience such troubles too

Re: alsa and intel8x0-sndchip onboard AC97Audio troubles

sidenote...

why compiling modules into the kernel? this wouldnt have much impact..

you just have to compile everytime a kernelupdate comes along to only have a shorter or emtpy lsmod... *shrug*

sidenote2...
*agree*iphitus
sticking to ALSA is fine.. if it works for you.. if not you have to use something else ... 

sidenote3...
esd, artsd, ... i didnt want to use a sounddeamon... just eats up performance and does not work for everything (eg. DooM3  ) .. beside.. it at least adds latency to sound leading to insync for DVD-playbacks eg.

sidenote4...
hopefully alsa supports "Southbridges" soon so i can switch back
