RE: Anyone have bluetooth headset working (for phone)? - wibble - 06-22-2021
@awaittrot why use ffmpeg for the loopback rather than pulseaudio's module-loopback?

If pulseaudio has good manpages, I could have used that.
Anyway, thanks for suggestions and I will try module-loopback later.

I've mostly avoided pulseaudio until recently so wondered if there might be problems with its loopback. You probably want to specify a shorter latency than the default 200ms too. I ought to look into how the audio profile thing works...or perhaps skip direct to pipewire since that's where things are heading.

Just a small update to my previous post. I can confirm that module-loopback works fine and latency is much lower than ffmpeg.
Code:
# mix modem audio
amixer -c 0 cset "name=AIF2 Digital ADC Capture Switch" on
amixer -c 0 cset "name=AIF2 ADC Mixer AIF1 DA0 Capture Switch" on
# mute internal mic and speaker
amixer -c 0 cset "name=Mic1 Capture Switch" off
amixer -c 0 cset "name=Line Out Playback Switch" off
mod1=$(pactl load-module module-loopback source=$source_pine sink=$sink_usb latency_msec=20)
mod2=$(pactl load-module module-loopback source=$source_usb sink=$sink_pine latency_msec=20)
echo Press enter to stop
read l
pactl unload-module $mod1
pactl unload-module $mod2
amixer -c 0 cset "name=AIF2 Digital ADC Capture Switch" off
amixer -c 0 cset "name=AIF2 ADC Mixer AIF1 DA0 Capture Switch" offRE: Anyone have bluetooth headset working (for phone)? - calinb - 06-27-2021

Whenever I grow tired of dealing with the Bluetooth buzzing, I plug-in to the headphone jack and it always works for me. In fact, my Bluetooth headphones support the copper wire connection too!

Just wanted to confirm that the plain old wired headset model I purchased (Road King model RKING910) does indeed work!
The sound out of the ear piece is a little "tinny" but it is loud enough (some other headsets I used were not). Also this is a very cheap headset, available in any truck stop in USA. People I talk to say I sound great though, and they can hear little or no background noise from my end.
Very happy to be able to finally be using a real GNU/Linux phone while driving[0]! And I will continue to tinker with bluetooth stuff when I have time, as ultimately wireless would be ideal. Thanks to everyone for clues to investigate in that area going forward.
[0] For anyone who may be unaware, holding a phone in your hand is now illegal in almost every state in USA.

Yup--I think you can still hold a map or have a conversation with a passenger in the car (found to be highly distracting and the reason the FAA, many years ago, adopted the "sterile cockpit rule" prohibiting unnecessary conversations below 10,000' for airline pilots many years ago).
I think you can still touch or hold a paper map or driving directions with your hand though (and maybe a dim flashlight to read them in the other hand at night
)...just no electronic versions of them which, operationally, can be far less distracting than paper, if used intelligently.I also think that wearing ear/head phones would probably result in a moving violation in many jurisdictions so, it's like I tell all my flying students, "fly safely and don't get caught doing it!"

How can you tell someone is a pilot, don't worry they'll eventually slip it into the conversation.
How do I know?
So I had food poisoning and I was doing my final approach runway 13 when....
(I need the puking emoji) FWIW I know some hams(amateur radio) who wear low impedance(heli/mil) Clarks(big ear cup aviation headset) or similar while driving thought that proves nothing, and they were approved while driving for intercom and hearing protection on fire engines almost everywhere in the 90s.

Once the wife was driving and she was yakking so intensely with another passenger that she sailed right through a red light. (Fortunately there was no cross traffic!) There are many distractions in a car. On modern cars with touch-screen controls it can be almost impossible to do anything without taking your eyes off the road. (Mine is old with dedicated switches and buttons and I know where everything is without having to look.)
I just keep my phone turned off in the car. Other than a medical emergency there is nothing that can't wait. So that's one less distraction.

That's really funny (and true) biketool! I'll pass it on to my pilot friends.
The main reason I disclosed (dropped) one of my previous fields of employment (I'm old and retired now--except for flight instructing for fun) is I wanted to use my "Fly safely and don't get caught doing it" line and advice, which is applicable to many highly government-regulated activities in life!

I've seen that happen too, Zebulon, but my relating it would probably lapse into another pilot story.
