My name is Chris, and I worked the balenaSound project to give old hifi stereos bluetooth compatability. Great project and I loved working it. I also decided to
install a DAC as well because I enjoy audio fidelity. However it was here that I ran into some issues.
First and foremost I was able to work the problem. It goes as such; when installing the DAC there needs to be some config changes. It is specified that the
BALENA_HOST_CONFIG_dtoverlay = hifiberry-dac did not work for the IQ Audio DAC+ that I specc’ed for this project. Instead I needed to set the dtoverlay parameter to
iqaudio-dacplus which took some digging to find but I got it eventually.
This brings me to my actual point: I believe the balenaSound project should be updated to reflect differences in DAC devices and should include some type of blurb about how
different DAC devices may require a different parameter than the one specified. Below is a link covering the dtoverlay parameters for IQ Audio’s various DAC devices. I’m sure
there are more out there that have yet to be found. The aim of this thread is to provide discourse on this particular change and I invite all to discuss the implications,
good and bad, of such a change. Thank you for your time.
TL;DR I believe the balenaSound project should be updated to reflect differences in DAC devices.
