Change kernel .config with menuconfig:

Device Drivers ? Sound card support ? Advanced Linux Sound Architecture

(64) Pre-allocated buffer size for HD-audio driver

Please enter a decimal value. Fractions will not be accepted. Use the ?

<TAB> key to move from the input field to the buttons below it.

Change 64 to 2048

Ok

Save

Changes kernel .config

CONFIG_SND_HDA_PREALLOC_SIZE=64
