+A regular question that occurs is
+"what is the pinout for the PortaPack speaker port"?
+![HackRF Portapack speaker connector J1](https://media.discordapp.net/attachments/719669765253365763/723224990182277270/Captura_de_Pantalla_2020-06-18_a_las_14.17.35.png)
+
+The pinout is quite simple.
+A speaker has 2 wires, SPK+ and SPK-
+
+At rest, a speaker floats on a magnetic field in the middle of it's range. When SPK+ is high the speaker moves forward. When SPK- is high the speaker moves backwards. The distance forward and backwards depends entirely on the voltage level.
+
+On the PortaPack, the speaker connector has 3 pins.
+
+SPK+ is the pin nearest to the edge of the board
+skip the middle
+SPK- is towards the centre of the board
+
+When you add the new speaker you may find that there is no audio. By default the speaker is disabled.
+
+To enable the speaker:
+Settings
+UI Settings
+Ensure Hide H1 Speaker option is disabled (a red X)
+Click Save
+
+Now a speaker icon will be present on the top line of the display.
+If the icon has an X it is muted. You can click on it to unmute, it will turn green.
