And the file located at:
/usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz (use gunzip to unzip it)
The section on snd-hda-intel contained the following:
Note 2: If you get click noises on output, try the module option
position_fix=1 or 2. position_fix=1 will use the SD_LPIB
register value without FIFO size correction as the current
DMA pointer. position_fix=2 will make the driver to use
the position buffer instead of reading SD_LPIB register.
(Usually SD_LPLIB register is more accurate than the
position buffer.)
My current configuration: Ubuntu 8.10, alsa 1.0.20, pulse audio 0.9.10, using equalizer via ladspa
The module parameter appears to be extremely important.
Other things which may or may not be important:
In /etc/pulse/daemon.conf:
resample-method = src-sinc-best-quality (I've also used speex-float-1)
default-fragments = 5
default-fragment-size-msec = 25
I just added this comment over on Bug #301755, but feel that it might be applicable to this one too:
I just had good success with adding a parameter to /etc/modprobe. d/alsa- base.conf:
options snd-hda-intel position_fix=1
I got the idea from: ubuntuforums. org/showthread. php?t=843012
