How can I stop my Mac from automatically using my [input only] USB microphone as an output devie?

I have a 2015 MacBook Pro on the latest version of High Sierra. I often use a USB microphone for Skype, etc. When I plug in the microphone, my Mac automatically detects it as an input source. This is good. However, it also automatically detects it as an output source, which is not good at all, since the microphone has no output capabilities. Every time I plug in the microphone, I have to go to Sound preferences and unselect it as the output.

Turn off automatic microphone muting

I have a Samsung Galaxy Tab E 9.6, which I used with the built-in Android 4. Now I updated to 6 (CyanogenMod 13) and since then the microphone is behaving really perplexing.

No matter which voice recording application I use (I tried some of them), it is muting whenever I don’t speak for a split second. Of course it turns on again, when I speak again, but nevertheless, this sounds quite weird, is there a way to turn this “feature” off?

Thank you very much!

Feeding audio to Gboard from other sources than microphone

Google has released a new improved speech recognizer for Android and Gboard, see here: link

Normally, you use Gboard with the microphone, but this could be kind of interesting with audio from other places.

Does anyone know if the Pixel hardware supports an audio mixer that would allow sourcing audio not from the microphone, but from the application that would allow using the new Gboard speech recognizer?

18.04 microphone w/ google voice typing, works intermittently

When I use google docs voice typing, in order to start microphone function (even though I have tested it to confirm that it is working at that moment), I have to unplug and replug the usb cable of the camera/microphone. When I pause my recording and restart it, again I have to unplug the mic and replug it so that it records. Just to emphasize, when the mic is not recording in google voice typing, I have confirmed that it is functioning in audacity and the sound settings.

Microphone recording has slight static and crackling despite all attempts at solving it

Exactly what the title states. I have a microphone that works well on Windows but regardless of distro, there’s always some slight crackling when using the microphone.

I have tried everything, adding load-module module-hal-detect tsched=0 to /etc/pulse/, fiddling with the voice levels on alsamixer, you name it, I tried it, and it didn’t work. It continues to crackle no matter what I throw at it.

I’d appreciate any solutions you might offer.


Microphone not working when connected to Bluetooth FM transmitter

When connected to my FM transmitter, I am able to hear audio from calls but they can hardly hear me.

Similarly, if I want to use Google Assistant, I have to shout. I believe the issue is that a microphone on the transmitter is being used as opposed to the microphone on my phone, and this microphone is bad. However, this has always been an issue, even when the device was new 3 years ago.

I can’t seem to find info on the exact model of transmitter that I have, but this was the title on Amazon: Car FM Transmitter W 2.4A USB Charger, Nulaxy™ 2015 Newest Wireless Bluetooth FM Transmitter Car Kit for All Smartphones, Tablets, MP3 Players Sold by: DinoSonics

It seems like there should be a setting for choosing which microphone to use when connected to a Bluetooth device, but this doesn’t appear to be an option. For reference, I am currently using a Pixel 3, however the same issue was present with a Pixel 2, Droid Turbo 2, and Galaxy S5, obviously on many versions of Android. If this is the wrong board to ask this question or if any more information is needed, let me know.

Multi-Output Device: include my microphone in QuickTime screen record

I was able to create a multi-output device included is Soundflower and my headset.
enter image description here

In Quick Time; Soundflower is selected to record the other party’s audio. enter image description here

In a meeting; I am able to record the audio coming from the other party’s end but I could not record the audio coming from my mic. Am I missing a configuration?

Im hinted at the volume slider in the screen recording but it feedbacks like crazy even at the 2nd lowest possible value

Microphone stopped working 1809 only (no updates installed)

Son has a Plantronics HD1 headset with microphone. Yesterday microphone worked. Today it didn’t. Windows 10 1809. No patches installed since 26th December.

All PCs here have all privacy options “Let apps access [device]” set to deny. (And Windows states this only blocks apps from accessing the device, not Windows – and by extension Win32 programs).

On my 1709 PC with “Let apps access my microphone” set to Deny it works fine.

On 1809 I had to temporarily “allow users to control” for this permission, then turn it on in privacy options and the microphone works. This should be a temporary solution only – as he was pestering me to get it working.

But I want to isolate the real cause of the problem because I will not be enabling any of the privacy options on any PC in my home.

I’ve been through all the troubleshooters, and checked all settings, uninstalled and reinstalled the device, rebooted, and so on… Nothing solved the problem.

So, guru’s, I’d value your thoughts on what might have resulted in it suddenly ceasing to work, when nothing had been changed on the PC between yesterday and today.
