What package for playing CD and midi file

ciotog · 09-20-2005, 01:12 AM

Well, ALSA setup assumes that they'll be modules, you should be ok if you just leave out the modprobe entries that correspond to built-in drivers.

I'm sure the LFS team made those choices because of the onboard chips are so common these days, but if you don't have an intel chipset on your motherboard building in the snd-intel8x0 driver is pointless for a custom build. Do they not recommend changing kernel config options to optimize the kernel?

Hi ciotog,

Before recompiling kernel I made following test;

download alsa-driver-1.0.10rc1.tar.bz2 from
ftp://ftp.alsa-project.org/pub/driver/

bash-3.00$ cat /proc/asound/oss/sndstat

Code:

It seems having built-in ALSA in the kernel. Whether to disable it?

I've build everything I need in the ALSA tree as modules (except OSS Sequencer API doesn't show as a module with menuconfig for some reason...), then you don't really need to get alsa-driver, and the rest of the setup process should work fine. Most of the ALSA setup documentaion assumes that you're using all modules, that's partly why you're running in to so much trouble.

I would recommend going through everything from "Sound card support" down and change [b]all[b] built-in to module. You can also drop Intel8x0, ymfpci and emu10k1 since they don't apply to your hardware, but having the modules built won't hurt, they just won't be used.

Having said that, I prefer building just about everything else that isn't required at boot time as modules as well - for example the cd-rom filesystems, SCSI (unless you have a SCSI HDD), etc. Here's my lsmod output:

You also want to enable module unloading. In the spirit of LFS you should really go through every single entry in config, read what it's about and then make your decision whether it's necessary for your hardware. It's time consuming, but definitely worth the effort!

Hi ciotog and folks,

To my surprise after installing XMMS, I can play music CD. I haven't recompiled the kernel to up the respective SND modules yet. What I did were as follows;

On xterm ran following commands;

# amixer set Master 80% unmute
# amixer set CD 80% unmute

Then I can play music CD on XMMS. I still have following problems unsolved.

1) Each time booting up the box I have to run the above commands again. Is there a way to set "unmute" permanent.

2) I have to start XMMS as root
$ ls -l /usr/bin/alsamixer

Code:

-rwxr-xr-x  1 root root 61555 Sep 20 06:59 /usr/bin/alsamixer

which of the following method will be more appropriate to allow "satimis" playing music CD

a) # chown satimis:satimis /usr/bin/alsamixer
OR
b) # chown root:alsamixer /usr/bin/alsamixer
# groupadd alsamixer

Please shed me some light.

Installed "timidity" to play midi files. Unfortunately it did work. I made following test;

bash-3.00$ timidity -Aas Midi_Guitar/

Code:

Couldn't open output device

bash-3.00$ which timidity

Code:

/usr/local/bin/timidity

bash-3.00$ ls -l /usr/local/bin/timidity

Code:

-rwxrwxr-x  1 satimis satimis 874598 Sep 20 08:24 /usr/local/bin/timidity

I have no idea whether it is the problem of its installation or something else. "timidity" works on FC3, the host, without problem.

I already ran following commands

# amixer set PCM 80% unmute
# amixer set Line 80% unmute

Any advice would be appreciated. TIA

I imagine LFS uses BSD style init scripts, so you should have the file /etc/rc.d/rc.local - this is where you'd put any local initialization like

Code:

alsactl --restore

This would have to be after you've got the alsa settings set and saved using

Code:

alsactl --store

If you have to run xmms as root, check the permissions on xmms. For security reasons you shouldn't have alsamixer or xmms owned by anyone but root. I think it would be beneficial to finish installing alsa (are there any snd- entries in /etc/modules.conf?)

ciotog · 09-28-2005, 09:58 AM

I was wrong, LFS suggests you use SysV init scripts rather than BSD. You'll have to research where to put your local initializations.

I'm also not sure how your system is handling module loading on startup - it would probably be beneficial to check out information about modutils and module-init-tools. I'm pretty sure that ALSA is assuming you have /etc/modules.conf and / or /etc/modprobe.conf - if you're using a different module loading scheme (such as using /etc/sysconfig/modules) you'll probably have to add entries for ALSA yourself.

One other thing, there is no module called snd-modules or snd-module. If you're trying to load all the sound modules you'll have to do each individually.

Whitesocks · 09-30-2005, 01:15 PM

For restoring the sound levels at boot, you can use the recommended bootscript from the alsa-utils setup instructions:

http://www.linuxfromscratch.org/blfs...lsa-utils.html

You can skip the "alsactl --restore" part of ciotog's instructions if you are using the bootscript and have followed the instructions on the above page to add the dev.d script and so on.

satimis · 09-30-2005, 09:57 PM

Hi Whitesocks,

Alsa is now working properly. I can play midi files with Timidity as well as music CD.

Quote:

I already completed this page previously.

The remaining problem is where to put following commands;

Code:

modprobe snd-pcm-oss
modprobe snd-pcm-oss
amixer set Master 80% unmute
amixer set CD 80% unmute
amixer set PCM 80% unmute
amixer set Line 80% unmute

So that they can be evoked at boot.
