alsa -- need help

[newmario]

Hi everybody,

my english isn't so good, i'am really new to gentoo and i need help with alsa


alsa freezes my computer

also if i start kde with arts installed, my computer crash.
or when i click play in xmms, crash.

i have installed alsa the same way like in the alsa guide, 4 times until now, but after every reinstall the same problem.
the modules seems to be correctly installed, alsa alsasound loaded the modules with success (no error report from alsasound).
alsamixer does also run.
my system is a xp 1800 with a terratec dmx fire 1024
alsa utils and alsa tools also installed, currently version 0.9.8 i think, but the error also occurs with alsa >= 1.0.2
my kernel version is 2.6.3-gentoo-r1

i have also run the MAKEDEV.snd script, but also no success.


i hope, anybody can help me, i have no idea, since 2 days i work to get alsa work and nothing
happens than crashes.

[Kabuto]

lsmod output:
[...]
cs46xx 64140 0
ac97_codec 17164 1 cs46xx
soundcore 7648 2 snd,cs46xx

By this it look like you are loading OSS also.

[newmario]

yes, but but without oss it crashes also.

[newmario]

maybe anybody can tell me some debug programs like strace or log files with debug output from alsa.
/etc/messages and strace say nothing.

[Kabuto]

You can't have OSS and Alsa loaded at the same time. You have to pick one or the other. (This doesn't have anything to do with Alsa's OSS Emulation)

[newmario]

make modules_install always install snd-ac97-codec.ko,
but i did not choose this option in the kernel config.

maybe this is the problem, i don't know, from where this module comes from.

[Kabuto]

ac97_codec that I showed is OSS. the snd_ac97_codec is Alsa. You can see in the lsmod:

ok, the oss modules are away, but it crashes again,

i'am confused, because i can start the alsamixer, kmix etc. and all show the correct sound card.

[newmario]

a error message

bash-2.05b$ aplay /usr/kde/3.2/share/sounds/pop.wav
Playing WAVE '/usr/kde/3.2/share/sounds/pop.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono
ALSA lib pcm_hw.c:523:(snd_pcm_hw_drain) SNDRV_PCM_IOCTL_DRAIN failed: Input/output error



what does this mean ?

alsa lib error ?

[MighMoS]

I don't know why, btu I've heard some people say it works better if ALSA just gets built directly into the kernel.

[newmario]

when i compilte the sound into the kernel, do i need to edit the alsa.conf and run modules-update ?

[MighMoS]

You shouldn't have to.

[newmario]

now i have compiled all into the kernel instead of using modules

its strange, if i try using aplay after booting with set the volume and unmute via amixer$
the following error appears

Playing wave '/usr/kde/3.2/share/sounds/pop.wav' : Signed 16 bit Little Endian
Rate 44100 Mono
ALSA LIB pcm_hw.c: 523:(snd_pcm_hw_drain) SNDRV_PCM_IOCTL_DRAIN failed : Input/$

when i directly call aplay with pop.wav after the first try, the computer crash$

maybe my computer components the problem ? via k7vt2, xp 1800.
