--- Comment #20 from Christian Birchinger <joker at netswarm.net> ---
The kernel documentation for CONFIG_SND_HDA_PREALLOC_SIZE has this:

Note that the pre-allocation size can be change dynamically via a proc file
(/proc/asound/card*/pcm*/sub*/prealloc), too.

I don't have any "pcm" sub directories in /proc/asound/cardX. I have only this:

~ $ ls /proc/asound/card3
codec#0  eld#0.0  eld#0.1  eld#0.2  eld#0.3  eld#0.4  eld#0.5  id

I also couldn't find anything similar in /sys/class/sound. Is there still
a runtime config somewhere or am i forced to rebuild the kernel every time
to experiment with this?
