Subject: [PATCH 0991/1085] allo-boss-dac mute output when changing parameters
|
|
|
|
Since I noticed that sometimes changing sample rates causes some digital
|
|
quirks and noises, I've changed the function to mute the output before
|
|
performing the changes and then unmute it when an error occurs or the
|
|
parameters got set.
