Chromecast Audio accepts up to 24-bit / 192kHz PCM .wav and .flac files via (amongst others UPnP Server) and plays them in full resolution. Could we add 24-bit support at different sample rates, including 88.2kHz, 96kHz, 176.4kHz and 192kHz into this mkchromecast project ? And if possible, could we also add the preferred bit-depth and sample rate to the dropdown menu ?
