Is Media center really passing audio as is?

balky:
Just tried MC22 on a spare Pi today and can say there is a huge improvement in library buildup speed, recognition of sound card... etc...
For the first time, I select the audio device to use, it worked right away...

For some reason I can't understand, it seems like there is a kind of internal sampling / re-sampling or whatever that is going on...
The high-end seems to be somewhat laid back compared to MPD... and audio sounds overall somehow distorted...

I have set audio leveling, turned off volume control, et al, but it looks like there is some kind of internal de-esser in the chain that is keeping the high end kind of shallow...
The DSP studio shows the same sample rate in / out and all seems to be passed untouched but overall quality says something is going on to me...

Hardware is a Pi 2B with HiFiBerry Digi+ running ALSA.
I built the system ground up from a minibian install to ensure nothing pulseaudio ever shows up.

I won't label myself an expert, but I'm not a newbie either...

I really want to move away from MPD if possible largely due to the fact that MC is more user-friendly when you get it to work...

Any suggestions?

Thanks

What device are you choosing in MC's audio settings dialog?

balky:
the following devices both worked...

- hw:CARD=sndrpiHifiberry,DEV=0[ALSA]

- default:CARD=sndrpihifiberry[ALSA]

balky:
Something else I am seeing now is a huge lag in switching from a playing album to another one and irregular dropoff / reconnect while audio is playing...

Delay is the 30 - 40 seconds range...

Using JRemote, Pi is connected wired gigabit network

Thanks

Use the HW device. The default probably uses the system mixer.
