[gentoo-user] Alsa Question

[Silvio Siefke]

Hello,


i have build the kernel without modules, all what i need i built in Kernel
fix. All Howto i see for alsa from Gentoo is with modules, but what i must
do, when i have fix in Kernel. The Sound with VLC goes without Problems, 
but for example mplayer give no sound and when i visit Youtube or so i have
no sound. 

Can help me someone or have a link what i must do?

Thanks for help. Nice weekend.

I beleive that if you build the sound card driver into kernel alsa cann have problems 
detecting the card. but once alsa has detected the card it should have no difference 
weather you built it into kernel or not.

I was having problems detecting all the sound devices of my card (as shown in 
alsamixer) when I had alsa built in the kernel.  This was particularly 
problematic for capture devices - external microphones were not showing up.  
From what I recall the devs advised that alsaconf and alsactl require alsa 
drivers to be built as modules so that they can probe the soundcard with 
different options as they load these modules.

That advice made me build alsa driver as modules from then on and my problems 
were resolved for good.

Gentoo's alsa-guide.xml is outdated and is incorrectly suggesting the 
use of alsaconf

When in reality alsaconf doesn't work at all with sys-apps/kmod because 
it doesn't generate 'modules.pcimap' and 'modules.usbmap' files anymore

And in version 1.0.27 of alsa-utils in ~arch the command is no longer 
being installed

So whatever you do, forget about `alsaconf` right from the start, since 
it's no longer required with modern PCI, USB, ... cards because 
sys-fs/udev automatically loads the required drivers
The `alsaconf` command has been useful only for old PCMCIA and ISA cards 
for years already

Instead you don't do anything else than unmute the mixers using 
alsamixer, and leave the module loading to udev

As in, edit/write /etc/modprobe.d/alsa.conf by hand only if you need to 
pass some options to the modules

So in VLC i have sound, i have set in option in audio/device
HDA Intel, ALC272 Analog Default Audio. The Problem is mplayer 
and Opera/Browser. What i must do there? Must i let run alsa in
runlevel default?

Thank you & Greetings

Re: [gentoo-user] Alsa Question

[Silvio Siefke]

Hello,


i have found the problem, i has create the .asoundrc with content:

siefke@gentoo-mobile : ~ $ cat .asoundrc 
pcm.!default {
    type hw
    card Intel
}
ctl.!default {
    type hw
    card Intel
}

Now have sound in Opera and in Mplayer. I have read the Howto from
Arch. 


Thanks all & Nice weekend
Silvio

I am still running media-sound/alsa-utils-1.0.26-r2 here and a couple of 
months or so ago I tried rebuilding all sound modules in the kernel, only to 
confirm that some devices were again no longer available.  Building them as 
modules restored them back as they were.  So for my setting at least I have 
stayed with sound built separately as modules.

Also, I had to use the install feature of modprobe to get the modules to
load correctly as udev did not load all the required modules.  Before it
was done by an init script.
