And if you didn't forced 24bit, maybe you are using software volume?
I thought (@Tim Curtis can you confirm or deny this ? ;-) ) if software volume is used, MPD uses 24bit.
You have a good memory!
Yes, MPD software volume will force 24 bit.
The OP has an IQAudio DAC+ which should support Hardware volume.
OP here.
CORRECT I was using software volume.
Changed to HW....and now this looks sensible to me.
[*] Encoded at 16 bit, 44.1 kHz, Stereo FLAC
[*]Decoded to 16 bit, 44.1 kHz, Stereo, 337 kbps
[*]Output rate 16 bit, 44.1 kHz, Stereo, 1.411 Mbps
[*]Output mode ALSA Direct (hw)
[*]Output chain MPD -> hw -> Device
...I know the docs said to use hardware (I did read the docs ) but it made no sense to me as I don't have a "hardware" (physical) volume control on the RPi/DAC
Or is that not what it means?
The help for volume setting says;
- Hardware: Use audio device on-board volume controller.
- Software: Use MPD software volume routine (32 bit float with dither).
- Fixed (0dB output): Assumes external analog or digital volume controller is used.
So does it mean the volume control capability built into the "DAC Hardware" rather than a physical volume control?
