do you have lib32-libpulse that is listed in the skype optdepends?
Comment by Stefy (Steve1984) - Friday, 07 June 2013, 15:11 GMT
of course yes and it has always worked, so it is not a missing dependency
thanks anyway

for me skype & pulse are still working, but somebody else on G+ had the same problem. he added this line to his and got things working again:

load-module module-equalizer-sink

[edit: neither he nor i understand exactly why that's so; he found it via google somewhere.]

my friend you saved my day, that does the job, i have got to say that pulseaudio is starting to get a bit on my nerves !!!!
bye bye from UK

I had the same issue today, and the linked fix also worked. I also needed to add the "tsched=0" param to to get rid of some bad gapping/crackling under the new pulse, as described here: (audio was not perfect pre-upgrade, but it definitely got worse). To avoid this just being a "me too", I will mention that this is on a Thinkpad T420s, so this is on the snd_hda_intel driver.

I have the same issue but neither "load-module module-equalizer-sink" nor "load-module module-udev-detect tsched=0" help me.

have you removed your users pulseaudio configuration and merged the pacnews like it is noted in the post_update() message?
Comment by Aleksei (yupi) - Saturday, 08 June 2013, 22:01 GMT
I never had any per-user configuration. Everything (and Skype) worked fine before.
BTW, I am on Thinkpad W510, the same snd_hda_intel driver.

The only way for me to have sound in Skype now, is to kill pulseaudio (pulseaudio -k) and restart Skype.

Starting Skype with PULSE_LATENCY_MSEC=30 should allow things to work. Maybe this workaround could be added to the launching script.
Comment by Ivan Lyapunov (dront78) - Friday, 14 June 2013, 06:54 GMT
Please add this to a launch script
Comment by Rafael Fontenelle (josephg) - Sunday, 16 June 2013, 10:21 GMT
'skype PULSE_LATENCY_MSEC=30' didn't work for me, in pulseaudio 4.0-2. All I get is a constant noise.
Comment by Adria Arrufat (swiftscythe) - Sunday, 16 June 2013, 17:46 GMT
I confirm adding PULSE_LATENCY_MSEC=30 to the launching script helped.
This is the Exec line in the .desktop file:
Exec=/usr/bin/env PULSE_LATENCY_MSEC=30 /usr/bin/skype
Comment by Rafael Fontenelle (josephg) - Sunday, 16 June 2013, 17:57 GMT
What Adria said works for me. Just remember to add "%U", like:
Exec=/usr/bin/env PULSE_LATENCY_MSEC=30 /usr/bin/skype %U
Comment by Kari Hreinsson (karihre) - Sunday, 16 June 2013, 21:29 GMT
Starting skype with PULSE_LATENCY_MSEC=30 worked for me as well. Would be nice if it were included in /usr/bin/skype.

  • Field changed: Percent Complete (100% → 0%)
The fix in skype does not work with the shell builtin "exec" when using zsh:

/usr/bin/skype: line 13: exec: PULSE_LATENCY_MSEC=30: not found
