Solved [Complex] Internal Microphone on FreeBSD 13R

This is about a simple thing-
Since my internal microphone wasn't working I connected a simple wired iPhone earphones (3.5mm jack)
Need to record audio and listen to using Chrome. Since this is a well known accessory I think this should be supported.

Here is the sysctl and dmesg after that:

Here is the problem now:
I set the following:
sysctl hw.snd.default_unit=1

I started audacity and set recording src as /dev/dsp0 and played it using the earphones through /dev/dsp1. Everything worked fine!

Later I set sysctl hw.snd.default_unit=0 and started chrome. I was able to record audio, download it and play under Audacity but not using Chrome!

If I wish to listen to audio via Chrome I have to set sysctl hw.snd.default_unit=1, close and start Chrome and I can listen to audio, BUT cannot record audio then!

Any idea how to make Chrome do both record audio AND play it at the same time?

Is this a Chrome issue or my weird microphone setup?

Firefox records but the audio is distorted, it's like someone is speaking with their mouth full of unchewable popcorn while being behind 20 glass windows with thundering and rains pouring.?️??️
 
The easy way would be to use and install audio/virtual_oss
And to have this settings in /etc/rc.conf
Code: 
virtual_oss_dsp: -T /dev/sndstat -S -i 8 -C 2 -c 2 -r 48000 -b 24 -s 8.0ms -R /dev/dsp0 -O /dev/dsp1 -c 2 -d dsp -t dsp.ctl
virtual_oss_enable: YES
The hard ways would be to play with the audio pins to have a single device with both audio output and record.
 
I uninstalled ESR and used the non ESR FFX now along with virtual_oss and it works now. Recording using inbuilt mic and audio out via earphones. Thanks.
