I'm afraid I can't find the setting. However, I tried to set
CONFIG_SND_HDA_PREALLOC_SIZE to 2048 as suggested in the doc since my
system is supposed to run pulseaudio [1], but anyway it hasn't changed
anything than with the default (64) value.


[1] even though I don't really know what this setting is supposed to
improve -- I can only guess a bigger value avoids resizing the buffer
every time if a bigger size is needed?
