 |

Hi....
I have been beating my head against this so long now I cannot see straight. The sound on my PC will not work right. Instead of playing normal audio, all I hear are crispy, cracking sounds where the music or sounds spike. If the music or sounds have no high point (db historgram), then I just don't hear anything.
I have been looking all over the place in the gentoo forums and all over the Internet, and I've tried a million different options... my head is spinning.
My system has 3 sound devices, and all of them use snd-hda-intel -- making this more complicated. I would happily disable two of them if I only knew how. Blacklisting won't work, because they all use the same module. I don't know if the cracking has something to do with the fact that this module is shared with 3 cards, or if it is something else -- but just to simplify things, I think it would be best if I could just disable 2 of them.
I don't think this is a pulse issue. I think it is an alsa issue. I seem to get the cracking even on the command line using speaker-test.

I have tried a million permutations in all of the files. For a while, it even seemed to be working... but for no explicable reason. I turned on the PC today, and the sound sucks again. I made absolutely no changes in configuration between when it last worked, and this morning. The only thing I can think of is that I plugged a set of USB headphones in for a couple minutes...
I would have assumed that this was soft support in the kernel, or even bad hardware... but I know the hardware is good, because it works under Windows (dual boot system). I know the sound can work under linux, because it did for a few weeks there.
If anyone can offer any advice on how to simplify, troubleshoot (and if there is a God), fix this, I'd be most appreciative.
Thank you.
G

speaker-test still uses pulse if available, as pulse provides an alsa wrapper.
To make sure: chmod -x /usr/bin/pulseaudio; killall pulseaudio, then try again. It should directly be using ALSA now. |

Thank you. I will give that a try... sound is miraculously working again for the time being... though I don't know for how long... I will keep this trick in mind for the next time it goes wonky on me.
Thanks.

I actually found this thread because I had a similar problem. Crackly sound that appeared randomly after a reboot. It only happened through Pulseaudio, hence the suggestion of trying without if you get this problem again.
For me, it also randomly disappeared again. Hell knows what that was :/ Pulseaudio, eh... |

I really think it is related to multiple sound cards of the same type.... I wish I knew how to turn them off. I only need one. But I cannot seem to find any help with that either. It is easy if they use a different driver, but when they use the same driver... I don't know. I have tried different suggestions I found from googling, but they never worked.

First, the last options in alsa.conf are not reliable at all even if one can find theme anywhere. I tried to set card order and such with that and got no sound in return.
Second, I did not know the `defaults' keyword nor that maner to set up device/card with `.card' suffix. Again try something simpler and common for this kind of issue. Again, try to group everything in ~/.asoundrc and output directy to specific device with an app to test everything beforehand without any fancy option. Lastly using`type hw; card PCH' would reliably select a card without any uncertainty.

OK. I tried this, and ruled out pulse. Still not working.
tclover, I'm not sure I follow you... can you give me an example?
Thanks.

Well, first your `/etc/modprobe.d/alsa.conf' could be faulty here because of the last line: setting card order like that is not reliable (at least I had issues in the past.)
Second, your ~/.asoundrc uses line like `defaults.ctl.card 1' which I did not know... nor the `defaults' keyword. (Is this a new way to configure sound cards?)
Anyway, your might use some sanitized/legacy-syntax to configure the sound card first; and second, use a simple and single file to do so (~/.asoundrc) to be able to debug.
Third, you can use card name instead of id to be keep a consistent setting even if the order of card change with `type hw; card PCH' syntax.
Lastly, as it seems you have the same integrated audio chip as what I use, you could grab my `~/.asoundrc' and set the default to DMixer instead... by following my sig./dotfiles for the sake of using something tested (with JACK/DMix/Zita...) everything works with Intel-HDA audio card--just choose a default: DMixer for you.
Last resort approach is to switch to OSSv4 (an ebuild is available in sig./bar-overlay or the intertubes (search in gpo.zugaina.org).)

It's not a new one, it's actually the far more sane one than that cargo-culted snippet in /etc/asound.conf (though I'm not sure if defaults.pcm.device line is needed).
I kind of wonder if all of those option lines in /etc/modules.d/alsa.conf are getting applied or is it simply that the last one wins...
Did you try without that /etc/asound.conf snippet ? |

Ok... something weird is going on here, but at least I have learned that there is a pattern here.
The sound problems only occur when I boot to my windows 8 partition, then reboot (soft boot) into linux. If I'm using windows and do s full shutdown, then restart the computer, this problem does not occur. How weird is that?
