I am able to follow the setup of the Balena Sound tutorial and everything works fine. The problem comes when I try to get my DAC working. As soon as I make the changes in Balena Cloud I am greeted with no sound and errors like this: /usr/bin/bluealsa: SBC decoding error: No such process 23.09.19 15:49:20 (-0700) bluetooth-audio /usr/bin/bluealsa: SBC decoding error: No such process 23.09.19 15:50:38 (-0700) bluetooth-audio /usr/bin/bluealsa: SBC decoding error: No such file or directory 23.09.19 15:50:57 (-0700) bluetooth-audio /usr/bin/bluealsa: Missing RTP packet: 1538 != 1536 23.09.19 15:50:57 (-0700) bluetooth-audio /usr/bin/bluealsa: Missing RTP packet: 1540 != 1539 23.09.19 15:50:57 (-0700) bluetooth-audio /usr/bin/bluealsa: SBC decoding error: No such file or directory 23.09.19 15:50:57 (-0700) bluetooth-audio /usr/bin/bluealsa: Missing RTP packet: 1584 != 1580 23.09.19 15:51:01 (-0700) bluetooth-audio /usr/bin/bluealsa: SBC decoding error: No such file or directory 23.09.19 15:51:01 (-0700) bluetooth-audio /usr/bin/bluealsa: Missing RTP packet: 1855 != 1854 I can revert back to the onboard 3.5mm but that defeats the whole purpose of using the DAC for my setup. Any insight would be helpful ---

Hi there! Thanks for trying balenaSound. Could you let us know what DAC you’re trying to use and what overlays or other configuration variables you’re adding or changing to enable it? Depending on which one you’re using, usually you’ll need to add an overlay and disable the on-board audio in the device configuration. ---

Hey @chrisys , Im trying to use the IQAudIO DAC+. I am following the directions of the tutorials so I an using the `BALENA_HOST_CONFIG_dtoverlay` set to `hifiberry-dac`. Everything else is vanilla from fresh install ---

@Had42 hmm I’ve not tried that DAC before, are you sure it uses the same overlay? Anyhow, if you haven’t done it already, go into device configuration and modify the line that says `"i2c_arm=on","spi=on","audio=on"` to `"i2c_arm=on","spi=on","audio=off"`and let’s see if that makes a difference! ---

@chrisys, thank you for the quick replies and pointing me in the right direction. Turns out there is an overlay specific for these boards. Once I used `iqaudio-dac` everything works and sounds so much better
