Raspberry pi 3 b - problem DSD native

Postby sbeuz » June 2nd, 2017, 10:33 pm

Here we go...

I have Raspberry pi 3b with Raspbian (Debian Linux) and a Denon DA10 DAC.

When I use it with fedora 25 and last mpd version 0.20.8 I have no problem to read DSD files in native mode (DSD32..)

However under Raspbian on Raspberry pi 3 b with the mpd service I couldn't read DSD files in "native" mode but "dop" mode works.

So I installed the 0.20.8 version of mpd under Raspbian and I have the same problem...

It's as if the signal for DSD native wasn't send to the DAC !?

In my mpd.conf I just add :
dsd_usb "no" in Alsa output for native DSD...

Please help me if you've any ideas...

@sbeuz, based on my experience, your issue most probably has to do with an older mpd version that usually debian project provides.

If you have a look here:

http://git.musicpd.org/cgit/master/mpd.git/plain/NEWS

You will see fixes for DSD_U32 even in version 0.20.2. I am not sure if raspbian provides such a new version:

https://packages.debian.org/search?keywords=mpd

As I see here, even the unstable branch is stuck at 0.19.x.

If I were in your shoes I would compile the latest mpd and I would check with that.

I compiled mpd-0.20.9 on Raspbian (jessie 8) with Boost and libasound2-dev libraries to enable alsa.

I can read DSD files with dop mode (S32_LE) but when I try to use the native DSD mode I don't have a DSD32 (I use cat command to see the DAC status).

Reading the file in native DSD is OK but I don't have any sound and S32_LE is used instead of DSD32 !?

Ok, I didn't see in the download section the Debian packages (outdated and unsupported by this project). Sorry...
