<p>Migrated comment #993</p> <p><b>New page</b></p><div>I have the x735 v2.1 working on a Pi 4B running Buster.<br /> However it doesn’t work when I plug a HiFiBerry DAC + Pro due to conflicts with GPIO.<br /> <br /> The Pi system just halts after the DAC kicks in from the script /etc/x730pwr.sh<br /> HiFiBerry states the GPIO18 the sound interface in hardwired on the Pi so it can’t be mapped onto another pin.<br /> <br /> GPIO18 is only used for software shut down $ x730off that I’m not going to use<br /> Reference script /usr/local/bin/x730shutdown.sh<br /> <br /> I have re mapped the GPIO4 and 17 in script /etc/x730pwr.sh and still no good so it must be down to the GPIO of the x735 being activated from the DAC!!<br /> <br /> Question is has anybody else managed to get the x735 v2.1 working with a HiFiBerry DAC + Pro?<br /> <br /> Or do I get another Power Management Unit?<br /> Or a different DAC?<br /> Or dump the PM Unit idea altogether?&lt;!-- migrated from Comments; original IP: 91.84.191.182 --&gt;</div>
