[Gnome 3] Skype sound has gone turned to crackly mess

Ok so I would class Linux sound management as one of my weakest points by a long shot if I had to rate my thoroughly mediocre Linux all over knowledge.

I am aware that having shifted to Gnome3 means a shift to PulseAudio which I can deal with, but I guess that also means that I can only play one sound stream at once?

While experimenting, I managed to get skype working neat enough, but I then out of sake of experimentation installed the multilib 32 bit pulseaudio libraries. Now Skype and only skype has reduced to nearly static, everything else sounds absolutely fine. All my sound outputs in skype settings point to "PulseAudio Server" and that is the only option. Which leads me to two questions.

1. I thought that the multilib 32 but pulseaudio libraries were mandatory for Skype to work, wtf was my skype outputting through and how do I get it back?

2. Is there an additional layer of abstraction I could add which would allow multiple streams?

thankyou for your time.

Re: [Gnome 3] Skype sound has gone turned to crackly mess

Historically sound servers were introduced to allow to play multiple streams at once. Nowadays ALSA supports playback like that natively. Pulseaudio, being a sound server, of course allows it too.

Does it work okay if you uninstall lib32-libpulse?

Make sure you follow https://wiki.archlinux.org/index.php/Pulseaudio#ALSA

Re: [Gnome 3] Skype sound has gone turned to crackly mess

Thank you Lucke for that little nugget of knowledge,I really need to read up on this stuff.

As expected, uninstalling libpulse32 got me my sound quality back, but now I've realised what's happening.

With libpulse32, Skype is forced to broadcast through the sound server and comes out a static ridden mess. Without libpulse32 it's hooking straight into the soundcard device and locking it down, it's all or nothing, So logic dictates that if I want Skype to be able to play nicely with all my other applications, I need to get the PulseAudio server into the equation somehow. Any thoughts?

Re: [Gnome 3] Skype sound has gone turned to crackly mess

Did you follow the part of the wiki article I pasted? Removing/blacklisting snd_pcm_oss and installing lib32-libpulse might do it for you. Having pulseaudio-alsa and lib32-alsa-plugins installed won't hurt either.

Re: [Gnome 3] Skype sound has gone turned to crackly mess

Hey sorry for the delay in replying, I should have been more specific.

I followed the wiki to the letter just to be sure.

32bit PulseAudio is installed, 32 Bit Alsa-Plugins installed, pulseaudio-alsa is installed. snd_pcm_oss blacklisted. Still crackly. I'm totally out of my frame of knowledge here sad

Re: [Gnome 3] Skype sound has gone turned to crackly mess

It's not so much a microphone problem in that any sound effect generated by Skype is crackly. Any sound that is being played at the same time succumbs to the crackling for the duration of the Skype sound. I have managed to google some possible solutions that involve joining various local groups, which leads me to the question, how to I admin groups on Gnome 3 O_o.

Well it's more of a browser "problem". Here's the link I gave you:

https://wiki.archlinux.org/index.php/Skype#Monster.2Flow-octave_.22growling.22_distortion_over_mic

Notice that it's meant to take you to this part of the wiki: "Monster/low-octave "growling" distortion over mic"
Now, your browser reaches the end of the document and can't move lower.

tl;dr check the links when you see "#"s.

Re: [Gnome 3] Skype sound has gone turned to crackly mess

I guessed that part...

But for the sake of argument, I followed the reccomendations there to the letter. Creating a dumy Alsa output killed all my sound, and deleting shared.xml did nothing.

Run "gpasswd -a group user" as root to add the user to the group.

Re: [Gnome 3] Skype sound has gone turned to crackly mess

Update: Removed the fix mentioned by Bangkok_manouel doesn't return sound. Gnome now will not acknowldge any soundcards exist. Reinstalling fresh pulseaudio packages isn't rectifying the matter.
