Squeezlite and Volumio on minidsp shd

Help and Support Help
1

Hi,

I am using a minidsp SHD device. It is a room correction system using dirac and features a dac and additional an undefined arm board with volumio on it. There is a plugin for Volumio to run squeezelite. The version is v1.8.7-999. It is compiled with libwiringPi. The dac is supposed to be connected via I2S. I managed to compile the library and get the plugin to run.

Now The Question:

squeezelite -l gives me several devices:

null - Discard all samples (playback) or generate zero samples (capture)
default:CARD=sndsun8ii2sdac - snd-sun8i-i2s-dac, - Default Audio Device
sysdefault:CARD=sndsun8ii2sdac - snd-sun8i-i2s-dac, - Default Audio Device
dmix:CARD=sndsun8ii2sdac,DEV=0 - snd-sun8i-i2s-dac, - Direct sample mixing device
dsnoop:CARD=sndsun8ii2sdac,DEV=0 - snd-sun8i-i2s-dac, - Direct sample snooping device
hw:CARD=sndsun8ii2sdac,DEV=0 - snd-sun8i-i2s-dac, - Direct hardware device without any conversions
plughw:CARD=sndsun8ii2sdac,DEV=0 - snd-sun8i-i2s-dac, - Hardware device with all software conversions
default:CARD=Codec - H3 Audio Codec, - Default Audio Device
sysdefault:CARD=Codec - H3 Audio Codec, - Default Audio Device
dmix:CARD=Codec,DEV=0 - H3 Audio Codec, - Direct sample mixing device
dsnoop:CARD=Codec,DEV=0 - H3 Audio Codec, - Direct sample snooping device
hw:CARD=Codec,DEV=0 - H3 Audio Codec, - Direct hardware device without any conversions
plughw:CARD=Codec,DEV=0 - H3 Audio Codec, - Hardware device with all software conversions

If I take the sndsun8ii2sdac I only get noise which turns on and of if I start palying or stop.
I I take the H3 Audio Codec I get nothing.

It is the same, when I use the latest squeezelite from sourceforge.

Any idea why this is so?

The Volumio player works fine, but I have a complete Squeezebox environment so I prefer to use squeezelite.
Any help would be appreciated.

If possible, turn on resampling on LMS to 32bits and use the i2s device.

3

As far as I know, resampling is done by squeezelite and only a maximum of 28 bit is supported. Is there any other way?

4

Ok, then 16bits will do. There is a current issue with the i2s driver on this device that will result in white noise if playing 24bits material

5

I added

-R v:::16

as extra parameter for resampling with 16 bit precision in squeezelite plugin. No change, white noise. It doesn’t even play internet radio which is definitively 16 bit.

Hi, unfortunately I don’t know and don’t use squeezelite, so I really can’t help much with your issue.
We optimized the Minidsp build to work perfectly with Volumio, I really can’t say why it does not work with squeezelite.
In any case, I will investigate.

Hi Michelangelo,

I got it to work after rereading the manpage of squeezelite over and over again.

The important switch is the alsa parameter tab in the plugin ( -a on the commandline) you have to set it to:

80:4:24:0

then all pcm stuff plays.
If you add extra parameters in the following way, it even plays dsd with resampling:

-r 44100-196000 -R vE:::24

Finally it works :slight_smile:

Great to hear! Well done!

Hi Michelangelo,

I got squeezelite up andd running until yesterday. The version 1.046 only produces noise, no matter what I tried. Maybe you can fix this soon. So far I went back to a raspi using PiCoreplayer.
