Radxa 5B Pro with Microphone via audiojack

ROCK 5 Series 5B/5B+

Hi

I’m try to stream video via HDMI and audio via a microphone that it’s connected to the headphone audio jack with a connector that splits the input to headphone and microphone (https://www.aliexpress.com/item/1005002628498600.html)

I’m not able to hear anything from my devices:

this is the ffmpeg command
ffmpeg -thread_queue_size 1024 -f pulse -i hw:CARD=rockchipes8316,DEV=0 -hwaccel rkmpp -f v4l2 -r 50 -input_format bgr24 -video_size 1920x1080 -i /dev/video0 -c:v h264_rkmpp -rc_mode AVBR -b:v 8M -minrate 4M -maxrate 10M -profile:v main -level 5.1 -f rtsp rtsp://localhost:8554/starium

Bump!

Any update about my question?

try this instead of pulse -f alsa -i hw:0,0 (or 1,0)

4

No success.

Radxa team. Can you help? How I’m able to use audio jack with microphone?

Hi

I already tried to do it without any success :frowning:
Not with ffmpeg and not with alsamixer

I’m connecting the microphone directly. Should I use any kind of adapter?

14

Any progress in here?

15

I’m so sorry for busy on other things for a while, I have reproduced the problem, I’ll try to fix it today.

16

Cool! Waiting for the workaround… thanks a lot!

17

Hi, Any progress about it?

18

It’s fixed in our debian image, I’ll submit the patch to armbian.

19

Cool! thanks a lot!
Can you send the link to Armbian PR once you submit it?
