MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
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 13/16] added an option to aseqnet to optionally set the midi
process name
This option allows to run multiple instances of aseqnet without having
to double check the assigned port number, since each one can get spawned
with a unique name.
Fixes: https://github.com/alsa-project/alsa-utils/pull/95

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.
