I’d like to get a microphone working via the Audio Panel Header (J511), but have had no luck so far.
Is this possible? From the Xavier Dev Kit Carrier Board Spec:
Table 14. AudioPanel Header Descriptions Pin# Signal_Name CODEC_Name Usage/Description Type/Dir ========================================================= 1 IN1P IN1P Mic #1 Output 2 GND ---- Ground Ground 3 IN2P IN2P Mic #2 Output 4 AUD_GPIO4 GPIO4 Audio Dongle Det Input 5 AUD_HPOR HPO_R HeadPhone Right Input 6 AUD_MIC_JD MIC_IN_DET Mic Detect Input 7 SENSE_SEND NA Pulled to GND NA 8 KEY NA NA NA 9 AUD_HPOL HPO_L Headphone Left Input 10 AUD_HP_JD GPIO3 Headphone Detect Input
The Type/Dir column direction seems reversed to me.?.?.?
Anyway, do I want to use IN1P or IN2P?
Do I need to do anything with Pin#6 or any other pin? (Tie high, low?)
Is any software setup required besides what is in Ubuntu Sounds applet?
