I came across the "output rate" information: listening to radio stations on Bluetooth speaker, it shows 1.411Mbps. Is this related to digital transfer rate of data over Bluetooth ? If so, is there any way to lower it ?
Thats the rate that MPD outputs to the audio device. The rate is determined by MPD and ALSA and it depends on what the audio device reports that it accepts.
In the case where the audio device is a remote Bluetooth Speaker MPD is not outputting to a physical audio device but rather to the input side of the Bluetooth stack managing the wireless connection to the Bluetooth Speaker.
My understanding is that the input side of Bluetooth stack requires 16/44.1 PCM which it then feeds into the SBC XQ CODEC that transmits it across the wireless connection to the Bluetooth Speaker at around 450 - 550 kbps. If the Speaker's Bluetooth stack doesn't support SBC XQ CODEC then the standard SBC CODEC will be used and that bitrate is ~320 kbps.
