No sound with DAC2 Pro on RasPi 3B

None

I have had a RasPi with a Digi+ Pro card on it, which has been working great for a year. (Optical out to a stereo receiver.)

I just swapped that card for a DAC2 Pro, and sent the output to analog inputs. No sound. I tried both the RCA red/white jacks, and the mini RCA.

/boot/config.txt has this:

#dtoverlay=hifiberry-digi-pro
dtoverlay=hifiberry-dacplus

(I just commented-out the old.)

dmesg shows this:

[    7.287717] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6

So that's not great.
But the HAT does seem to be detected:

root@raspberrypi:~# ls -l /sys/firmware/devicetree/base/dacpro_osc

root@raspberrypi:~# cat /sys/firmware/devicetree/base/dacpro_osc/name
dacpro_oscroot

What's my next troubleshooting step?

Thanks,

Jim

This looks just fine. It might be a hardware issue. If you want to check the hardware, it's usually best, to just boot HiFiBerryOS (https://www.hifiberry.com/os) from another SD card and check if this works.

I have my Raspberry Pi running headless. Does HiFiBerryOS have ssh enabled? Or do I need to plug in monitor & keyboard & mouse?

You can enable SSH in the web UI.

Ok, I finally circled back around to getting this configured with HiFiBerryOS .
Still no sound from the mini-RCA headphone out.

A lot of things look right. I plugged a monitor & keyboard & mouse into it, and enabled some sources. My control point (BubbleUpnp on a tablet) "finds" it as a renderer, and I can select it. When I queue up a song on my control point and press play, the green light on the sound card comes on. And the album art embedded in that flac file is displayed on the monitor thru HiFiBerryOS. When I change the volume on the control point, the volume slider (visible on the lower right of the monitor thru HiFiBerryOS) shows the changes.

Everything seems great, except no sound comes out.

Here's the last 15 lines from the /var/log/hifiberry.log file:

I thought maybe I had failed to seat the card properly on the RasPi pins. But with the card being "found" by the OS according to the log, and with the green light coming on when i hit play, seems the card is fully connected to the board.

# cat /proc/device-tree/model

What's my next troubleshooting step?

Is it possible I received a bad sound card? Any other way to rule that out?

Thanks,
Jim

It's possible that there is a hardware problem. We regularly see Pi's with defective GPIOs. Therefore, testing another Pi can be helpful.
If ths card connected directly to the GPIOs with no other stuff connected to the GPIOs?

I originally had a Digi+ Pro on this Pi, and that combo has been working fine for over a year.
I took the Digi+ Pro off of this Pi, put the new DAC2 Pro on it (and changed the dt-overlay settings), and now I get no sound.

Reformatted my SD card to use HifiberryOS, as a troubleshooting measure. Still no sound.

There's nothing else on this Pi. Just the DAC2 Pro sitting on top (plus cables plugged-in: power, USB for keyboard & mouse, HDMI for monitor, ethernet).

So, am I to the point where I should return the unit? Have we exhausted troubleshooting steps?

It might be a hardware issue of the board. I recommend to contact the dealer you bought it from.

Amazon.

I took too long to circle back to setting this up: return window closed a month or so ago. ☹️

I recommend the dealer you bought if from directly. Otherwise check how Amazon deals with warranty returns.

I involved Amazon customer service, and they advised me on a warranty claim, and the vendor replaced it.

AND IT'S WORKING!!!! 🙂
