I've just disabled KDE file search by unchecking "Enable file search" and "Also check file content".
First, KDE crashed, but recovered.
Now it is very very light and responsive.
Interesting. I am curious about what will lose after this.

Sound works fine for the second day, BTW. Thank you so much!

...and worked fine until the next update. Now, it pops again, but the configurations were kept...

I'm getting some popping and cracking too. Never had it before. When it happens, it seems like if I close applications and start them up again, the cracking is gone. I haven't found the cause yet.

Try reverting the configurations to what you had previously.

Previously to the update, or previously to the tuning as you described in the blog?
Right now, they are as in the blog.

Previously to the tuning described in the blog. See if that makes a difference.

I have. Re-installed PulseAudio too. No cracks so far, I think they will start after some VLC usage, but not even them from the beginning...

It pops.
Stupot, what sound card do you have? Is it Creative too?

1. Try changing PulseAudio's resampling method. Add the following to /etc/pulse/daemon.conf and restart PulseAudio (or reboot)

Code: Select all

resample-method=speex-float-0
The default in PulseAudio is speex-float-1 (which is commented out in /etc/pulse/daemon.conf to indicate it is the default).

2. Another thing to try is to change the line 'load-module module-udev-detect' to 'load-module module-udev-detect tsched=0' in the file /etc/pulse/default.pa.

3. Yet another thing to try is to launch audio applications as follows:

Code: Select all

$ PULSE_LATENCY_MSEC=30 vlc
