Puppy Linux Discussion Forum

there has been quite a few posts on the forum about puppy losing sound after a few boots, requiring alsawizard to be run again and again.

This fix worked for me in lucid puppy, and may work in other pups.

first off, when the sound is working, open /etc/modprobe.d/alsa.conf

Hello 666philb,

Nice to see someone addressing this issue. It is more complicated if you are running 2 soundcards. I have one computer which uses snd-hda-intel for the mobo card and snd-cmipci for the pci card so I can't blacklist them. I use them both to route audio from different programs to different destinations. At boot-up the process of allocation of index numbers is random unless I manually edit (add lines to) a different file at /etc/modprobe.d/alsa-base.conf eg:-

666philb, nice work.

I've had the random sound card numbering problem too, wasn't sure how common it was. Will have a look at the script.
; -)

edit: as far as i know modem cards should be blacklist for alsa?

Checked this with Puppy Linux 4.3.1.
(Post-reboot sound loss also occurs with 4.1.2, but not Wary or 2.14x.)

Location is different; it's in /etc/modprobe.conf

[darkcity]

does sound start working after running Alsa Wizard? it might be worth checking if any files are changed in /etc/mobprobe.d

also /etc/asound.conf and /etc/asound.state

----

On lucid528 I had problems with network card sometimes being reconised and other times not. Could also be a load order problem.

Dewbie,
Like 666philb I also had sound problems with early versions of Luci/Lucid.
Attached is a copy of the script I developed to solve my problems. If you wish
to give it a try simply extract and run it.

Hello ETP:

Thanks for posting!
I tried it with 4.3.1, but it doesn't work.

Even though Lucid and 4.x series both have audio-loss issues after rebooting, the causes are apparently different.

@OscarTalks
I've written a script along the lines of what you talked about - making it soundcard order automatic, see-
http://murga-linux.com/puppy/viewtopic.php?t=79829

@Dewbie
Thanks for posting the info, I've found a bunch of other files that control the current sound state in /proc/asound/ does the modules file differ from sound working and sound not working?

Okay, that thread is talking about a clash between two sound cards, or possibly a snd crd and a modem.

I occurs because different cards are loaded in differ orders at boot up.

Which Puppy are you wanting to use 4.1.2 or 4.3.1, does it have a alsa-base.conf file?

add this list if so-

# Soundcard order at boot-up
options snd-es18xx index=0

@darkcity

Excellent work! I feel this is an important issue and looks like you have made a major breakthrough. I will do some testing on my various machines over the next day or two and report back.

My oldest machine is the most interesting case. That one has a USB soundcard as the second one. Looking at /proc/asound/modules in that I see that 4 modules are loaded:-

0 snd_intel8x0
1 snd_mpu401
2 snd_intel8x0m
3 snd_usb_audio

In this case index 2 is the dial-up modem, but I am not sure what snd_mpu401 is. Looks like something to do with MIDI, but if something like that were to grab index 0 at boot then even with no extra soundcards I'm sure my sound would be gone. This module does not show up at all as a card in the list in Multiple Sound Card Wizard so I get one random number missing and the others randomly juggled around. The script will hopefully lock these numbers down.

I am not sure what the best final implementation of something like this should be. Maybe a separate tool, built into Multiple Sound Card Wizard or built into Woof since it may be advantageous to run it on all Puppies regardless of additional soundcards?

If you are taking the order from the list in /proc/asound/modules then I suppose you need to be sure that they are arranged in a satisfactory order before writing the lines to /etc/modprobe.d/alsa-base.conf

@666philb, would be good if some people with the same problem tested your fix.
