if 40kbps means the sampling rate is not 44.1kHz, then it is not outside SB1
spec, but it is outside SPDIF spec.  If you use the digital out, and SB1 sends
22kHz sampled signals, then many digital recievers will not do anything with
it.  Some work, some dont.  If you search the forum for Live365 or SPDIF, I'm
sure you will find more discussion on this. One such discussion can be found
here:

from Slimserver web UI, player settings->audio:

"Bitrate Limiting

SlimServer can automatically convert your music files to WAV/AIFF or MP3
on-the-fly to lower the bitrate of the data streamed to your player. This is
useful if you are connecting your player to SlimServer across the Internet or
are having intermittent problems using a wireless network. You can choose the
maximum bitrate that SlimServer will stream to your player. MP3 songs encoded
at a bitrate lower than below won't be converted. If you choose No Limit,
SlimServer will stream your MP3 files without conversion and your other file
types as uncompressed PCM audio."
