[gentoo-user] no audio

[gentoo-user] no audio

[maxim wexler]

Hi group,

For a 2.6.19.5 kernel on a PIII w/SBLive soundcard
using snd-emu10k1 module. I emerged alsa-utils and
mp3blaster.

Ran #rc-update add alsasound boot

Ran alsaconf and let it write /etc/modules.d/alsa. It
concluded with a tell-tale pop from the speakers and
the message that my sound card was set up and ready to
use.

But mp3blaster won't play. Msg is "Failed to open
sound device"

Noticed under /dev/sound there was no 'audio' or 'dsp'
nodes so I made them w/ mknod. 

No good, same msg. 

Set ENABLE_OSS_EMUL="no" in /etc/conf.d/alsasound and
rebooted.

Ditto.

Is this a configuration problem or a soundcard problem
or is mp3blaster to blame? 

FWIW modules loaded, alsamixer unmuted.

Maxim

There is nothing shown with 'dmesg'?

If you mean an error, no. 

Anyway, aren't you talking about the boot console?
I've never seen anything about audio in dmesg, whether
the audio is OK or not.

So, if you mean an error in boot console, no.

With the newer kernels, you don't need to do anything outside the kernel
for Alsa sound most of the time.  Make sure to configure the kernel so
that it has basic sound support enabled (I would compile this into the
kernel, not as a module, but that is me).

Next, on the menu where you choose options, leave OSS unmarked, and
select Alsa support.

On the submenu for Alsa support, select everything that applies (Do
select OSS Emulation, as some packages don't ASK which driver you are
using, they just assume the one they want is there).

If you select extra things here, it won't matter much.  The extra items
are just Midi drivers, and if you don't have Midi hardware, they aren't
an issue either way. ^_^

In other words, on this screen it is safe to select pretty much
everything.

On the screen for PCI drivers, select the option(s) appropriate for your
hardware.

'lspci' should show which sound card your system has.

If you are using devfs, then the device nodes should be created
automatically, if not then I am not sure how to create them manually in
an old style system.  It is possible, that you may need to manually
chmod a+wr the device node in order use them (This is assuming they are
there, which you said they were not I think).

Also dsp, should be /dev/dsp in many cases.  Many of the items you want
will be under /dev directly instead of /dev/sound  These may be links to
the /dev/sound items, but I am not sure. ^^;;  More experienced people
can probably tell you that.

Yes, I used lspci. That's how I know what module to
use. Also note kernel version. Definitely not "old
style".

Well, I have a SoundBlaster card too.  Mine works so let's see if this
will help.  Everything is built into my kernel, no modules.  My lspci
reports this:

This is my kernel stuff:

Maybe that will help.
