Build CONFIG_SND_HDA_PREALLOC_SIZE=1024 as is, but adjust the prealloc size later on the running system via echo to a proc file.

At the untouched state, confirm that it shouldn't work (it's 1024). Then change to 64, and check that it works. Then echo 1024, check that it's actually changed (cat the same proc file will show the current value), then confirm that it breaks again.
