Moode 6.4 on raspberry pi 4 with Beocreate
#1
Question 
Hello all! First I'd like to say that I enjoy playing music on moode using a raspberry pi and my Benchmark USB DAC feeding the music to Powered Speakers.  It has an excellent audio quality and getting better every day.

A week ago a decided to get another Raspberry pi 4 and use a I2S DAC+amp and make a head system for car to replace my old factory radio there.  Since I was limited to 12V power source  I found this Beocreate 4 channel amp from HiFi Berry and thought would be a nice match and will power up the raspberry pi too so no need for down convertor 12v to 5V either.

I'm testing this and so far everything works but the volume I'm getting to the speakers is way too low.  I do see that HiFi Berry Beocreate is in the list of supported I2S devices.  I have selected this and also switched to software volume in the MPD config.

Yes, I have removed the mute jumper in beocreate but the output volume on the speaker is too low, can barely hear it with volume at 100%.

Is there any other settings or configs to do in advance with Beocreate?  

Also is there a way that Moode can talk to a touch screen? This would be perfect for displaying content in a 7 in LCD while the system is installed in the car.

Thanks in advance,

Moode works well enough with the touchscreen. Not sure you'd want it in a car situation though. The screen itself can miss touches and Moode's UI isn't the most finger friendly.

I seeded a UI idea based on Spotify in Android Auto.

I have the same volume issues. I am using Polk Audio speakers, and I'd love to learn how to increase the volume.

Interestingly, I've also tried the HifiberryOS and set the speakers up for "Other Speakers" option and it too is extremely low volume.

I prefer Moode, and would like to make this work.

Any help would be appreciated!

Thank you,

Scott K.

Seems to me this is the wrong forum for questions about the Beocreate 4 amplifier's output. I suggest you ask them on the HiFiBerry forum.

According to a post from HiFiBerry I found on their forum, at full volume the DAC can output 2V with a 500 ohm load. That's what moOde will drive it to at 100-percent software volume and is at the upper end of the typical range of DACs. Should be fine.

If with that you're suffering low volume from your system then IMHO the problem lies in what's downstream of the DAC. 

Maybe you have the wrong DSP software installed. Quoting from https://www.hifiberry.com/beocreate/beoc...-software/

Quote:To use the Beocreate 4 channel amplifier with a 3rd party software, you first need to install a DSP program using the Beocreate software or SigmaStudio. After writing the software to the DSP and the EEPROM, the board will start up even without additional Beocreate software on the system (and even standalone without a Raspberry Pi connected).

In this context, moOde is a 3rd party software which knows nothing about loading Beocreate DSP software. You have to get the necessary info from HiFiBerry.

Maybe your Beocreate 4 and your speakers are mismatched.  I can find no technical specifications of any value in judging this.

Either way, I suggest you ask your questions on the HiFiBerry forum.

Thanks Kent, You are right that this really is a Hifiberry issue...

It was the DSP program installed onto the DSP at the factory (it is only for testing apparently). After installing/enabling hifiberry-dsp, I was able to update the DSP program to allow me to continue to use Moode...


I've been using the Hifiberry Amp2/DAC without issue in Moode, and thought it would be similar, and just work...

But, installing the https://github.com/hifiberry/hifiberry-dsp I can now update the DSP without having to boot into HifiberryOS. Win for Moode!

Thanks again,

Scott K.
