Describe the bug I can run procss with -a ALAW -A 8000 without any error but no audio found in RTSP. if I remove audio options, then I can get audio in default format S16_BE successfully.

To Reproduce Steps to reproduce the behavior: hardware: Pi zero 2 W + ReSpeaker 2-Mics Pi HAT + raspberry camera v2 os: Raspberry OS lite(buster) command: v4l2rtspserver -a ALAW -A 8000 -u unicast -P 554 -W 1920 -H 1080 -F 30 /dev/video0,plughw:CARD=seeed2micvoicec
