NO, just yesterday, i used Gentoo, with kernel 2.6.20, where one *has* to write that "snd-card-0" kind of things to get sound working. even latest Fedora Core 6 have those files hidden in the system.

Sorry, Arnuld, I am a little bit off topic. You have already answered some questions in another thread. Here are some hints, but probably doesn't help: - the default configuration files are in /usr/share/alsa (installed with alsa-lib port) and are usually sufficient. - I have the following /etc/asound.conf file pcm.!default { type plug slave.pcm "kombinace" } pcm.vystup { type dmix ipc_key 1024 ipc_key_add_uid 1 slave { pcm "hw:0,0" # format S32_LE period_time 0 period_size 1024 buffer_size 8192 rate 44100 } } pcm.dsp0 { type plug slave.pcm "vystup" } pcm.vstup { type dsnoop ipc_key 2048 ipc_key_add_uid 1 slave { pcm "hw:0,0" channels 2 period_size 1024 buffer_size 4096 rate 44100 periods 0 period_time 0 } bindings { 0 0 0 1 } } pcm.kombinace { type asym playback.pcm "vystup" capture.pcm "vstup" } - the simple aplay command works?

yes, i think it is sufficient and i should not touch that file.
- I have the following /etc/asound.conf file
i dont have any "/etc/asound.conf" file but i do have "/etc/asound.state". any problem with that. -- http://arnuld.blogspot.com/

Well, once the module is loaded, the alias has no influence anymore. Thus if you load the proper modules with modprobe, and don't get any sound, the aliases won't help. Again, reading the man pages for modprobe and its configuration would have told you that. > any ideas on getting sound working ? The following three steps have worked fine for me: 1. compile proper kernel (alternatively, add alsa-driver if you prefer to use those over the in-kernel ones) 2. reboot 3. set volume 4. enjoy music This has also worked with my EPIA CL10000 which has a Via AC97 sound controller.

Ok, i got it. it says "modprobe.conf" or all files under "/etc/modprobe.d" directory are a replacement for "/etc/modules.conf". then i added these to "/etc/modprobe.conf": alias char-major-116 snd alias char-major-14 soundcore alias snd-card-0 snd-emu10k1 alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss alias /dev/dsp snd-pcm-oss options snd cards_limit=1 then i did had a reboot and after that i tried this, as "root": "/etc/rc.d/alsa start". terminal said: "NO state is present for CARD V8237" then i did these 2 and i did not get any message: /etc/rc.d/alsa stop /etc/rc.d/alsa start then i tried to play the song using ogg123 and it HUNG :-(, same problem, it keeps on playing the 1st "1 sec" part of song for unlimited number of times, repeatedly.
any ideas on getting sound working ?

that is for CRUX 2.2. in CRUX 2.3, this just does not work -- http://arnuld.blogspot.com/
Hi, Okay, just to repeat that from my previous mail: if you build the sound drivers into your kernel, they're not considered modules. This means that anything you'd configure in modprobe.conf, modules.conf, conf.modules etc. won't have _any_ influence. Really. On Mon, May 07, 2007 at 08:07:55 +0000, arnuld wrote:

Ok, i got it. it says "modprobe.conf" or all files under "/etc/modprobe.d" directory are a replacement for "/etc/modules.conf".
then i added these to "/etc/modprobe.conf": As mentioned, unless you actually build it as kernel modules, this has no impact. Both howto's you mention before assume that you have build modules.
then i did had a reboot and after that i tried this, as "root": "/etc/rc.d/alsa start". terminal said: "NO state is present for CARD V8237" That's fine, since it'll try to recover a state when it wasn't stored before. This only happens the first time, as you saw yourself.
then i tried to play the song using ogg123 and it HUNG :-(, same problem, it keeps on playing the 1st "1 sec" part of song for unlimited number of times, repeatedly. As Pavel suggested, try more low level stuff first; aplay, or cat some data into your playback device.
The following three steps have worked fine for me: [...] that is for CRUX 2.2. in CRUX 2.3, this just does not work Well, that's at least a starting point. IIRC, neither of the two releases has sound support in the boot kernels, so in any case it was _your_ kernel that supported in on 2.2. Try to remember what you did differently.
In general, there was no difference between 2.2 and 2.3 WRT sound; both work fine for me with the previously steps. Johannes -- Johannes Winkelmann mailto:jw@smts.ch Zurich, Switzerland http://jw.smts.ch

YES, you are right. i saw this myself :-)

i tried "aplay" and it says "playing" but i do not hear anything then it gives this message: sh-3.2$ aplay beltry.wav Playing WAVE 'beltry.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: pcm_write:1265: write error: Input/output error sh-3.2$ i tried google with keywords "cat audio data linux" but did not find anything on how to "cat" an audio song.
In general, there was no difference between 2.2 and 2.3 WRT sound; both work fine for me with the previously steps.
so the BUG is in ALSA drivers ? -- http://arnuld.blogspot.com/
