[gentoo-user] ALSA - Still No Sound

[gentoo-user] ALSA - Still No Sound

[dhk]

I still can't get sound to work.  Can someone tell me what's wrong?  In
addition to my earlier thread below I have INPUT_DEVICES="evdev" and
ALSA_CARDS="AC97" in my make.conf.

The following that someone suggented does nothing.
> modprobe snd-intel8x0; modprobe snd-pcm-oss; modprobe snd-mixer-oss;
modprobe snd-seq-oss

I've also tried a second sound card and alternate set of speakers.  Also
nothing is muted or turned down.

According to http://kmuto.jp/debian/hcl/ my card works.

[Bill Kenworthy]

what does "lsmod" say?

This is on a jetway MB with an onboard nvidia chipset so not quite the
same as yours (only sound and the nvidia module are modularised) - in
particular make sure that you are building the "Intel HD Audio" codecs -
it isnt immediately obvious that its required.

Below is the full lsmod.  What are the "Intel HD Audio" codecs?  I don't
remember doing anything explicitly for them.  How do I check them?  Thanks.

Under the HD-Intel sound card driver menu there are several codecs for
specific sound chips.  e.g. I use the one for realtek, but yours may be
a different one.  Doesn't hurt to build them all as modules and see which
one(s) your kernel actually uses.

It looks like all the codec's are built in.  I'm not sure what the last
one in the list does.

# grep -i realtek /etc/kernels/kernel-config-x86_64-2.6.36-gentoo-r5
CONFIG_REALTEK_PHY=m
CONFIG_SND_HDA_CODEC_REALTEK=y
# grep -i codec /etc/kernels/kernel-config-x86_64-2.6.36-gentoo-r5
CONFIG_SND_AC97_CODEC=m
CONFIG_SND_HDA_CODEC_REALTEK=y
CONFIG_SND_HDA_CODEC_ANALOG=y
CONFIG_SND_HDA_CODEC_SIGMATEL=y
CONFIG_SND_HDA_CODEC_VIA=y
CONFIG_SND_HDA_CODEC_ATIHDMI=y
CONFIG_SND_HDA_CODEC_NVHDMI=y
CONFIG_SND_HDA_CODEC_INTELHDMI=y
CONFIG_SND_HDA_CODEC_CIRRUS=y
CONFIG_SND_HDA_CODEC_CONEXANT=y
CONFIG_SND_HDA_CODEC_CA0110=y
CONFIG_SND_HDA_CODEC_CMEDIA=y
CONFIG_SND_HDA_CODEC_SI3054=y
# CONFIG_SND_SOC_ALL_CODECS is not set

This is the genkernel so pretty much everything is built in.

Could this be a bug in the kernel?  I haven't had sound for about a
year, but I know it use to work on this hardware.  It probably went out
with an upgrade and never came back with a new install.

Any ideas are appreciated.

Thanks,

dhk

There is a very recent post from someone (Walter?) that says he got audio
only after compiling all the kernel sound features as modules, but he has
no idea why (nor do I) but, as no one yet has a better idea, I'd try it as
an experiment.

This probably won't make any sense, but for some reason I had good clear
sound for a few minutes today.  Since I've been working on other things
and audio is a luxury for me I haven't been trying to get it to work
lately.  However, this afternoon I plugged in the speaker and tried a
wave file and it played great.  Then, since the machine has been running
a for a while and I've done updates recently, I rebooted to have a clean
start.  I though it might get rid of the bouncing vertical scrollbar,
but that's another issue.  I was all set to play music and videos, but
after the reboot the audio wasn't working anymore.  Something somewhere
got the audio working only for it to stop after a reboot.  I checked
alsasound and it's running.  Any ideas?

Thanks

Did you check with alsamixer to see if Main or PCM or anything else has been 
muted?

PS.  I seem to recall on a dell machine where the sound would be muted 
inexplicably (I believe due to some hardware setting) that dual booting into 
MSWindows would fix it (i.e. unmute it).  As the alsa drivers were developed 
further this problem disappeared a few months later.

Because alsaconf needs to probe one module at a time and set its parameters.

Just to confuse things more, I have the same driver for my sound and I 
build everything into my kernel and always have.  The sound worked as 
soon as I unmuted it.

root@fireball / # cat /usr/src/linux/.config | grep REALTEK
CONFIG_SND_HDA_CODEC_REALTEK=y
root@fireball / #

Weird huh?

Like you, I used to build the lot into the kernel for years and it worked 
fine.  Suddenly it stopped.  With no other discernible changes at the time to 
blame for this I raised a bug.  The devs recommended that I should build alsa 
as modules and that fixed the problem.  I haven't yet tried to go back to 
building it all in the kernel to see if it would still work.

That makes it even more weird then.  I update at least on each number 
upgrade, 35, 36, 37 etc.  I don't think I have ever missed a version.  I 
never had sound problems like this.  Right now, I'm on this kernel:

root@fireball / # uname -r
2.6.37-gentoo-r1
root@fireball / #

I have to say tho, sound is one of those things that gets weird.  Being 
muted is a big thing people miss but it seems sound comes up pretty 
often, about like video issues with drivers.  It just makes me wonder.  
I use the same chip, no problems.  You have ran into problems in the 
past and changing to modules fixed it.  I have never used modules for 
sound or anything else.  What a head scratcher.  :/

Just plain weird.

It looks like I have the same thing.
# cat /usr/src/linux/.config | grep REALTEK
CONFIG_REALTEK_PHY=m
CONFIG_SND_HDA_CODEC_REALTEK=y

FYI: This is my main box, not my laptop which is a dual boot.  I haven't
tried setting up sound on the laptop yet.

Thanks

you can use 'lspci' in shell to know something about your sound card,then http://www.gentoo.org/doc/en/alsa-guide.xml      has a guide about how to set your hardware and kernel,the information used to make sure the model of your sound card is porvided in 'lspci',look it up clearly
if you don't know how to update the kernel,see herehttp://www.gentoo.org/doc/en/kernel-upgrade.xml

I think I have made some progress.  After getting a new sound card
(Sound Blaster X-Fi) and building X-Fi in the kernel I have some sound,
but it sounds terrible.  It's mostly a static noise with a hint of the
actual audio underneath.  Also the volume is almost all the way up, but
the volume still sounds low.

The ALSA Soundcard Matrix for this card says:
Sound Blaster X-Fi emu20k1 Details [PCI] Partially supported on 1.0.21;
EAX and Advanced sound options like crystalizer not available

and

# lspci | grep -i audio
02:09.0 Multimedia audio controller: Creative Labs CA0106 Soundblaster

I set the ALSA_CARDS variable in /etc/make.conf to emu20k1 and CA0106,
but neither make a difference.  When alsaconf is run it always set the
card as CA0106.

After each change I run alsaconf and alsamixer to make sure all is set
correctly.

When the ALSA_CARDS variable is changed, is there anything that need to
run or be updated?

The following 764 lines is the output from alsa-info.

I've got one of these X-Fi devices although mine is not a Creative
Labs device.. The device looks like a PCI-Express 1x devices but on my
motherboard it turned out it only works in one specific slot. Check
your MB specs for any similar limitations.

As for the in-kernel/module question, I've done Linux audio for years.
I can almost promise you that the Alsa devs never build the drivers
into the kernel. For that reason alone I never do. I've had a few
problems over the years when they were built in, later fixed by the
devs so that it worked built in, but in my experience it's always
better to start with it as a module, get it working, and then if it's
important to you build it in. I have about 2 dozen sound cards here. I
build all of them as drivers for every machine so that I can move
cards around for special needs and not need to rebuild the kernel.

Good luck,
Mark

Two dozen??? How many computers do you have?

For audio work I have six. 2-3 sound cards/machine. Typically 1
card/machine is dedicated to junk system sounds. The others run Jack
for more interesting audio work. (Recording live, soft-synths, etc.)

Many cards are just older things I've had for years. They will
continue to be useful until the machines die and I don't have PCI
slots in new ones to plug them into.

Here's an update.  Yesterday morning I recompiled the kernel, but I took
most everything out that didn't look like one of the three audio cards
I've been trying to get working.  I rebooted and tested the audio with
the new kernel and it didn't work.  Then I rebooted again before I went
out for the day, the machine ran all day and all night without any
activity before I logged in this morning.  Now I have audio again.  Now
I think I have to pay attention as to whether audio begins working after
a period of computer uptime.  Does this sound plausible?

I wouldn't think so.  /etc/init.d/alsasound should run at default
level, load modules and restore settings.  Assuming that you have run
the alsaconf command to unmute your channels, then you should have
sound straight off the peg.

However, I have an old laptop which always starts with the Master
volume control muted.  I have to press the special sound control
buttons on the keyboard to unmute sound every time I reboot.  I guess
this is a hardware quirk of this MoBo and it is the only PC that I
have come across something like this.

Here's an update.  The sound comes and goes.  I've been leaving the
sound on all the time now and not just when I need it.  I test it
frequently just to see if it works.  I haven't found any pattern other
than when I do a reboot or shutdown when the box powers up again
sometimes I have the audio and sometimes I don't.  However, even when
there's no audio it looks like the modules load and alsasound starts.

Another update.  It seem all I need to do to get sound back is run
alsaconf (take all the defaults) and reboot.  I'm not sure why it stops
working after two or three reboots, but if I run alsaconf again and
reboot it's back.  It never works right after alsaconf, it always needs
a reboot.  It would be nice if the sound state didn't get lost, but at
least I can get it back.  I'd also wouldn't mind knowing why it happens.

Thanks,
dhk

Does it really need a reboot, or does (as root)

/etc/init.d/alsasound restart

get it going?

Dumb question, but did you unmute the channels in 'alsamixer'?  I almost 
always had to do that the first time I configured ALSA.  For reason the 
defaults seemed to mute the channels.

Yes, all channels are unmuted.  Thanks.
