From: Nicholas Kazlauskas <nicholas.kazlauskas@xxxxxxx>
[Why]
In an effort to stop redundant calls to dce110_disable_audio_stream
the audio->enabled flag was added to the audio resource struct. While
this state probably shouldn't have been tracked on the audio struct
itself it still works fine for some sequences.
However, it does not work for cases where we're freeing the audio
resource (such as hotplugs) or when dynamic audio is enabled.
In these cases the pipe_ctx->stream_res.audio = NULL before we can
set audio->enabled = false. The next time we acquire the audio resource
such as on hotplug the audio will not be enabled for the stream since
DC thinks it's still enabled.
Audio state tracking should cover this sequence.
[How]
Set audio->enabled = false at the start as long as we have
pipe_ctx->stream_res.audio.
