[gentoo-user] ALSA: All modules loaded, mixer unmuted, still no sound

[Ducky Z.]

Hello,

The sound card works fine with Ubuntu in my other partition. I've
followed Gentoo's Alsa Guide and currently with kernel modules. But no
sound comes out when I play music or any other things.

The 'lspci' for my card is:

00:1e.2 Multimedia audio controller: Intel Corporation

The 'lsmod' for the OS is:

I've  searched in forums, and haven't found any solution yet. All
channels are unmuted and set to full. I hope some could help me out.

Thanks,

Did you look at your mixer?  Try alsamixer.

I've already unmuted all channels. Still no sound.

My aplogies I didn't read far enough........

Do you have any programs that will play sound?  I think I may have to bow out 
of this discussion.  It's always worked for me just fine (emu10k driver 
here).

Hello,

I've played through mplayer as well. While mplayer plays through the
file, I can hear no sound. mpg321 plays the files too except that it
shows some errors at first.

Are use using alsa provided by the kernel, or the kernel modules provided 
by alsa-driver?  What version of either the kernel or alsa-driver?  What 
version of alsa-lib?

Can you play wav files through aplay?  There should be some samples 
in /usr/share/sounds if you don't have other .wav files.

In addition to being unmuted are the outputs actually turned up?

You appear to have the right modules loaded, but those dmesg errors are 
likely because the userland is having problems talking to the kernel.

What's -nitro?  Is that your own kernel version string or is that like 
ck-sources?

I'm using the modules provided by the kernel, which is 2.6.15.
alsa-lib is 1.0.10.

When I aplay a file, it shows:

ALSA lib pcm_direct.c:900:(snd_pcm_direct_initialize_slave) unable to
install hw params
ALSA lib pcm_dmix.c:831:(snd_pcm_dmix_open) unable to initialize slave

Output means?

It's nitro-sources. I've used gentoo-sources, and I'm now trying nitro-sources.

Thanks a lot.

This should be fine.

Hrm....  Is this being done as root?  I think your /etc/asound.conf file might 
need some help.  I'm not sure here, but it might not be able to play because 
the wrong information is in the asound.conf file.

Means that PCM, MASTER are not set to 0 in alsamixer.  You said earlier that 
they were unmuted and turned up so I think you have this covered, but you 
should double check.

Well the workaround is to get programs using the alsa libraries to properly 
initialize the device.  Not sure what the configuration issue is.

Hello,

When I ran aplay as non-root user, the output seems worse :(

ALSA lib confmisc.c:672:(snd_func_card_driver) cannot find card '0'
ALSA lib conf.c:3493:(_snd_config_evaluate) function
snd_func_card_driver returned error: No such device
ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings
ALSA lib conf.c:3493:(_snd_config_evaluate) function snd_func_concat
returned error: No such device
ALSA lib confmisc.c:1072:(snd_func_refer) error evaluating name
ALSA lib conf.c:3493:(_snd_config_evaluate) function snd_func_refer
returned error: No such device
ALSA lib conf.c:3962:(snd_config_expand) Evaluate error: No such device
ALSA lib pcm.c:2099:(snd_pcm_open_noupdate) Unknown PCM default
aplay: main:544: audio open error: No such device

I've re-checked all the mixer levels :)

And finally, I don't have asound.conf in my /etc. Where does it come from?

Thanks again.

Hrm, is alsa-lib 1.0 backwards compatible to 0.9?  'Cause the kernel 
shipped with 0.9 support for a while and my kernel now has to have an 
option to provide the 0.9 abi/api.

You could try either upgrading your kernel or downgrading your alsa-lib.  
Or, you could abandon the kernel-provide modules and use alsa-drivers.

Yeah, try as root and if that works, check permissions on stuff 
in /dev/sound.

If you can get the 1.0 alsa-lib to work with your kernel, you can probably 
blow away your asound.conf file anyway.  The move to 1.0 made dmix 
automatic for devices that don't do hw mixing.

Re: [gentoo-user] ALSA: All modules loaded, mixer unmuted, still no sound

[Ducky Z.]

Hello,

I've removed kernel support for ALSA and using alsa-driver instead.
Still no luck and same error. And I still don't have /etc/asound.conf
or ~/.asoundrc. Is that a problem?

Thanks.

Re: [gentoo-user] ALSA: All modules loaded, mixer unmuted, still no sound

[Ducky Z.]

Hello,

Here are some more interesting output from dmesg while I was trying to
play a sound file.

PCI: Setting latency timer of device 0000:00:1e.2 to 64
intel8x0_measure_ac97_clock: measured 50457 usecs
intel8x0: clocking to 48000
ACPI: PCI interrupt for device 0000:00:1e.2 disabled
ACPI: PCI Interrupt 0000:00:1e.2[A] -> Link [LNKB] -> GSI 10 (level,
low) -> IRQ 10

Thanks.

No.  They are only necessary if you want to create non-hw based or hw+sw 
based alsa devices.  My people will have some because it used to be 
necessary to create a dmix device in order to enable software mixing.

If anything, the *presence* of an asound.conf / asoundrc would be more 
likely to be causing trouble than the *absence* thereof.
