Help with alsa sound persistence

[IanG]

Greetings all,

I've just started playing with TC after using DSL for a number of years. So far, so good.

I am having trouble getting sound to work on every boot. I'm using alsa which works fine if I run alsaconf from a terminal window after every boot, but the settings &/or configuration is not being saved on shutdown.

Other settings & extensions saving without problem.

Do I need to add something in the bootlocal.sh file or similar &, if so, what?

Using TC in the PPR/TCE mode, booting from CD, tce directory on a USB flash disc. PC is VIA EPIA 5000 with 700M+ memory. My final intention is to remaster everything on to a bootable CD so the kids can have an unbreakable(!) PC for web / flash / games, but it needs to boot & work without keyboard intervention as my youngest is only 3.

Many thanks in advance.

If your sound card works with the oss extension, it would probably be easier than using alsa - I believe you could have the extension load at boot then just add "soundon" to bootlocal.

I did try OSS sound first, but the quality was terrible (very distorted) and it didn't work at all with a couple of applications (running under wine).

Alsa works fine and sounds like it should, the only niggle being that I need to run alsaconf on every boot.

Just wondered if anyone else had the same issue & perhaps had a possible solution.

Many thanks.

... or did you mean something else?

Some live distros set up alsa automatically without calling upon alsaconf; SLAX, Knoppix are two examples.  Since I help maintain the alsa extension I will see if I can work up a script that can be either run on the command line or added to /opt/bootlocal.sh that would configure alsa automatically on boot.   

[Jason W]

I took the liberty of putting together a script that will setup alsa on the command line.  It is in the alsa_modules extension named /etc/init.d/alsastart. Put "/etc/init.d/alsastart start" in /opt/bootlocal and it should set up alsa upon boot.  If you want to save the settings, run the command "alsactl store" and then back up your /etc/asound.state file and the combination of these two should preserve alsa settings across reboots.  I have tested this on three machines and it works well so far.

Many thanks for the quick response.

I'm having trouble finding your script - I assumed I should reinstall the alsa_modules.tcem from the appbrowser, but when I did so, I couldn't find alsastart in /etc/init.d/. It looks as if the module has not been updated in the appbrowser.

Not surprisingly, nothing happened when I added /etc/init.d/alsastart start to /opt/bootlocal.sh !

Am I doing something stupid?

It seems to be in /usr/local/etc/init.d instead

[Jason W]

That's right, it does not get symlinked to /etc/init.d/ like alsasound does.

[Jason W]

/usr/local/etc/init.d/alsastart has been merged with /usr/local/etc/init.d/alsasound.  So the command would be:

/usr/local/etc/init.d/alsasound start

to boot with alsa loading automatically.  Basically alsastart was fixing the modprobing of alsasound, no reason to have it seperate.

[IanG]

OK - that seems to have fixed it. It's starting now.

Many thanks for the help!
