MIME-Version: 1.0

Content-Transfer-Encoding: 8bit
If load_configuration fails with open_failed == true, load_state will
jump to the out label without config being initialized and pass this
uninitialized config value to snd_config_delete. This commit fixes this
issue by initializing config with NULL and checking if it is non-null
before invoking snd_config_delete.

Subject: [PATCH 15/16] arecord: Inform users when 8-bit sampling is used on
tty
When we reverted 0c5948e ("aplay: try to use 16-bit format to
increase capture quality"), we should also handle the original
problem somehow. This code shows a warning with a hint to
the right parameter.
