I have this issue on a fresh install of 12.10 AMD 64. Sound was bad from

Thanks for answer #23, it solved my problem.
The problem occured only by VLC itself and the KDE Phonon VLC module. So
I suspect that VLC is doing something a little bit different than most
other audio backends. Maybe the chunk size VLC uses or the timing of

My five cents:
I just upgraded to Kubuntu 12.10 beta 2 AMD64 with full updates and the
awful cracking/echoing noise is still present in both VLC 2.0.3 and
Skype 4.0.0.8 x64. My system is AMD based with 785G chipset.
* The ¨rm ~/.pulse -rf¨ worked only for seconds until I closed and
reopened VLC;
Long time I have used this account. This problem happened in LinuxMint
Debian Edition - the core files are from debian. This is not Ubuntu
related, and upstream trouble.
How I recieved this crispy, fuzzy sound:
- I have edited /etc/pulse/daemon.conf and increased fragment amount and msec.

Ok, after restart the problem was back.. Even after I set the
daemon.conf back to default.
The solution in #23 helped however, thank you!
So, I will then create a report for this chip, this is Ax00 AMD chip

I can also confirm on Lucid Lynx. Removing ./pulse solves until reboot,

With workaround #23you disable time scheduled mode and switch back to
old interupt driven mode. The new time scheduled mode should save cpu
usage. The question here ist: why did the time scheduled mode work in
Maverick and not in Natty? And why is only vlc affected and none of the
other players?
I have to correct myself. The workaround by removing ~/.pulse directory was
only temporary. Some time later the distortions begun again on my MacBook.
Yesterday I got a new Acer Aspire One 521 Netbook and did a fresh install of
Natty. This fresh installation has the same problems with audio in
I can confirm that removing .pulse directory does *not* solves the problem for
me :-(
But I found an empirical solution that is perfectly reproducible for me and
maybe can shed some light on the problem:
1. start playing an mp3 with VLC - sound is distorted/crackling
2. while VLC is playing,
After posting the above information to a corresponding bug in Skype, another
user posted back a solution that definitely solved the problem for me for both
VLC and Skype (and I suppose every other source in PC with intel-hda chipsets):
I can confirm that removing .pulse directory made the problem with VLC
go away.
