If the DefaultAudioSink was reconfigured in a way that was compatible with the previous configuration just after having been reset, we would try to drain audio processors despite not having an AudioTrack. This could result in a NullPointerException if speed adjustment was active. Fix this behavior by only trying to drain audio processors if we actually have an AudioTrack. PiperOrigin-RevId: 235355466
