Mazda Mx-5 AA Hifiberry RPI3
#1
RPI 3 B+
5v & 5A max straight from 12v via a step down.
Hifiberry DAC+
No microphone
No Bluetooth dongle
7 inch rpi touchscreen
Android Auto 12
Mobile latest android auto from google play store
XIOMI M9 LITE

I have speakers in my car wired to a 2 way amp, then the L & R input from the amp directly to the HifiBerry sound card.

The speakers & amp have been tested both work fine.

Installing OpenAuto Pro no sound card was detected so I followed this tutorial.

https://www.hifiberry.com/docs/software/...ux-3-18-x/

Now the sound card is detected by the RPI and OpenAuto.

Everything works but no sound, I plug my phone in type c usb and the song plays on the RPI same for AA Spotify. The type C connection prevents the sound from playing from the phone but am yet to successfully get the sound to come from the speaker.

Any help would be massively appreciated.

If sound works on RPI, then what is the issue here?

There is no sound from the RPI.

Sound is not working.

Just that the configuration seems correct but still no sound.

I said the the speakers work fine when testing with other media source but no sound from the RPI.

Did you try to use generic USB sound card? In case of problems with HiFi Berry we suggest to contact HiFi Berry support at https://support.hifiberry.com/hc/en-us

I have not tried a usb sound card and I don't really want to I wanted a hifiberry for quality but I suppose I could test with a usb soundcard just for the sake of it. I will forward this on to hiffiberry then but I was my understanding that OpenAuto and been tried and tested with hefiberry devices.

Besides me not getting Audio working yet great work on the software. I have contacted Hefiberry and linked them this thread and I'll post back my findings once resolved.

OpenAuto Pro is based on regular Raspberry PI OS (buster version). We tested OpenAuto Pro with HiFi Berry devices but did not face any similar issues. Each HiFi berry device we tested was working out of the box.

I fixed it. It was my own fault I had spliced an earth and power cable and split them to the RPI screen and RPI board.

This must have been causing a lack of power which was enabling me to recognise the hifiberry but not enough power to output the sound.

I have now have the power and ground going straight to the RPI board and then a power and ground GPIO pin from the board to the screen, the hifi board then sit on a GPIO extender.

However Hifiberry DAC+ did not work out the box and here is a tutorial for anyone how want it.

Thanks for the tutorial.
As for the BT driver, does it mean you don't use an external BT dongle?
