Moode USB Output

I'm just as puzzled as Tim about this.

I'm using a Creative Technology USB-BT transceiver to drive my Sennheiser BT headphones here in our hotel room (some people, even my SO, aren't all that fond of Mahler!).

The DAC accepts only 48kbps 48kHz-sampled material (alsacap reports 2 channels, sampling_rate 48000..48000 Hz). It works fine with MPD, Spotify, and Airplay renderers with ALSA Default plughw which, as Tim says, is the only option for the Spotify and Airplay renderers.

Here's a sample output from the Audio info command (it's a screen-scrape so formatting is a bit wonky)

Code:

Audio information
Input / Output
Source Airplay stream
Encoded at Unknown
Decoded to 16 bit, 44.1 kHz, Stereo, VBR
Output rate 16 bit, 48 kHz, Stereo, 1.536 Mbps
Output mode ALSA Default (plughw)
Output chain Airplay -> Crossfeed -> plughw -> Device
DSP operations
Resample rate
Selective rate
CamillaDSP Off
Volume mixer Software (MPD)
Audio Device
Device Creative Bluetooth Audio W2
Mixer name PCM

The only difference between my audio path and yours that I've noticed so far is that there is no hardware volume control available in my DAC so I'm using the software volume mixer.

Hint: when setting up moOde, it's best to accept all the default settings and then make only the minimum changes needed to select the DAC being used. This has always worked for me. Everything can be fine-tuned to suit individual taste later.
