[gentoo-user] Sound problem

[gentoo-user] Sound problem

[Rafael Barrera Oro]

Hello everyone! I have Via on-board sound and i cant get the audio to work.

At first the problem was that /dev/dsp did not exist, so i loaded a
couple of modules into the kernel (mostly following www.gentoo.org
alsa-guide) after that, the error message became "could not open
/dev/dsp permission denied" so i tryied chmod a+rw /dev/sound/dsp
(also from gentoo docs) nevertheless, i stillo have no sound. For
example when using XMMS if choose to use the Alsa driver, an error
pops up telling me "failed to open audio output: Alsa plugin", so i
choose Arts which doesnt trigger any errors but there is stillo no
sound!!

i ran "lspci |grep audio" and this is what returned

00:11.5 Multimedia audio controller: VIA Technologies, Inc.
VT8233/A/8235/8237 AC97 Audio Controller (rev 50)

i had all the necessary kernel options (according to the gentoo doc)
built-in in the kernel, including AC97 so i am out of ideas.

If anyone has any clue of what i should do, it would be greatly apprecieated.

Thanks in advance

Rafael

I followed your advice Andres and its weird, there are now no error
messages anywhere to be found!! yet the sound does not work, i think
it is more of a curse, so i will subscribe to the exorcism mailing
list, anyway i will continue to hear your suggestions of course :P

Two things.  Build your audio drivers as modules.  Secondly, emerge
alsautils then use alsamixer to adjust your audio levels.  They're all muted
by default.

This is kind of along the same line of alsa mixer.
I use kde and fluxbox, but kde's stupid sound daemon wont let
some apps have sound, such as audacity or firefox.
When I use Fluxbox, the sound works, but _every_ time I
boot my computer into Fluxbox, I must unmute and level up
all of my sounds. Is there any way to save the configuration
past your session?
Thanks!

Problem solved! i compiled all the required drivers as modules and
then ran alsaconf, now my sound is finally working.

Thanks to you all

adjust the volumes, and run (under root)

/etc/init.t/alsasound save

or

alsactl -f /etc/asound.state save

or you can set SAVE_ON_STOP="yes" in /etc/conf.d/alsasound to save
volumes on every shutdown


all of these require that you have alsasound started at boot

[gentoo-user] sound problem

[-- Attachment #1: Type: text/plain, Size: 625 bytes --]

Hi all,

I have a box which runs gentoo, and the sound doesn't work. When i run
xmms, i get the following message:

** WARNING **: alsa_get_mixer(): Attaching to mixer hw:0 failed: No
such device

The sound is a Creative SoundBlaster Audigy (onboard my MSI K8N Diamond
Plus motherboard). Alsa is installed, and emu10k1 is compiled into the
kernel. When i run alsaconf, however, it cannot find my sound device.
Any help would be greatly appreciated.

Have you started the alsasound service? What do you read from lspci? and 
dmesg?
I think you forgot to compile some modules...

lspci reports "04:05.0 Multimedia audio controller: Creative Labs SB
Audigy LS"

dmesg says nothing about sound... it's been a while since i last
rebooted this box ;D

when i try to start alsasound manually, it says the following:

 * Loading ALSA modules ...
 * Could not detect custom ALSA settings.  Loading all detected alsa
drivers.
 * Unable to find any ALSA drivers. Have you compiled alsa-drivers
correctly?
 * ERROR: Failed to load necessary drivers
 * Restoring Mixer Levels ...
 * No mixer config in /etc/asound.state, you have to unmute your card!

which is strange because alsa-drivers are compiled into kernel.

maybe you didn't compile drivers that your soundcard uses.
try emerge alsa-drivers again...

alsa-driver is compiled into kernel, and emerge alsa-driver complains
because of it and exits.

Re: [gentoo-user] sound problem

[recordus]

when I compiled my kernel, I only selected "Sound card support",but
didn't select any module that is supported by the kernel(Alas or oss),
then I emerge alsa-driver, and it works well.

ps:my english is poor,sorry :)

well, i recompiled and broke the kernel :P

while i was trying to fix it, the livecd had the same problem as my
installation; it complained about alsa-drivers being compiled incorrectly.
Perhaps a bug?

[gentoo-user] Sound problem

[Bruno Gola]

Hi guys,
Good morning (in Brazil hehe) ;)


So, today's doubt is about sound... i can listen my mp3 with xmms, i can
play nfsu2 with cedega and sound works fine... but, when i try mpg123 to
play (as user) or play some game that uses /dev/dsp directly, i get this
error:

bruno@br ~ $ mpg123 MEDIA/MUSICAS/Sum\ 41/Does\ This\ Look\
Infected_/01\ -\ The\ Hell\ Song.mp3
High Performance MPEG 1.0/2.0/2.5 Audio Player for Layer 1, 2 and 3.

Uses code from various people. See 'README' for more!
THIS SOFTWARE COMES WITH ABSOLUTELY NO WARRANTY! USE AT YOUR OWN RISK!
Can't open /dev/dsp!


If i try it as root it works perfectly...

Does anyone knows this problem?

Thanks ...

Permissions on /dev/dsp

Either set /dev/dsp to be 666, or (better), add audio to your group.

The first thing that i've tried was that... permission... but no
success... (im in audio group already)...


Anyway, thanks the reply... :D

Check /dev/sound/dsp for the correct permission. On my machine /dev/dsp
was a symlink of /dev/sound/dsp and even though the symlink's permissions
were correct the permissions of the file it was linked to were not. For me
at least, adding yourself to audio wouldn't work as the files (well,
/dev/dsp at least) looked to be owned by root:root. I just had this
problem and doing a chmod o+rw /dev/sound/dsp solved it (I actually did
/dev/sound/* just in case).

If you have /dev/dsp0 or something like that, make /dev/dsp a symlink to 
your sound device, for example /dev/dsp0.

If something is trying to open /dev/dsp, then it is using the (obsolete)
OSS API.  You need to enable OSS emulation in the kernel drivers.

Note that, AFAIK, there is no mixing possible with the OSS API.  Your
best bet is to tell the apps to use ALSA, or use one of the dsp
"wrapper" libraries that are available.  If the app doesn't support
ALSA, complain!!

In the Linux kernel it may be deprecated but OSS is not obsolete. Other
operating systems besides Linux need sound after all :).

It does support mixing.

For the kernel, deprecated == likely to be removed soon == obsolete. 
Now, it is true that only the OSS drivers are deprecated, not the OSS
emulation provided by ALSA.

I have no problem with applications supporting OSS for operating systems
besides Linux, because as you say, that is the standard for those
systems.  I do have a problem with apps that insist on *only* supporting
OSS for Linux.  What really bugs me is that most of the offending apps
are commercial applications that don't even have ports for Solaris,
FreeBSD, etc!!  Besides, it isn't like supporting multiple sound APIs is
really all that hard....

According to the dmix HOWTO, you are correct, it should work.  I guess I
just gave up too easily, and I stand corrected.  Thanks.

The question is if the ALSA OSS emulation is a good idea. 
Because it exists, people are not urged to use ALSA.

That's true.

If an application tries to access /dev/dsp, DMIX does - AFAIK 
- not work transparently. INstead you have to start the 
application using the aoss wrapper, maybe aoss skype or aoss 
reaplay. This doesn't work convenient for the user.

Furthermore, there seems to be a bug so Skype will crash as 
soon as it gets invoked via aoss (I don't know if it is a 
Skype or an aoss bug).

So, if want to stay idle for incoming Skype calls, do not 
start any other sound application because Skype blocks your 
device...


Best regards

There is also OSS ALSA emulation.

I am admittedly not to familiar with Linux's implementation of OSS, it
could be that it is obselete and buggy. I have only used OSS in other
operating systems. In my experience mixing and/or dynamic virtual channels
are available with /dev/dsp through kernel/modules no userland
applications are needed. This all seems kind of irrelevant though, I
believe this guy is using ALSA with OSS emulation :p.
