18.04 – Output device is not listed in the settings, it is set by default to “line out”

I’m new to Ubuntu and the sound issue is giving me headaches. I’m using headphones however when I check the sound settings nothing is listed


I found a solution to this a week ago by installing pulse audio volume control and I selected headphones in output devices. However, when I do that, the sound is distorted and it cuts out the whole time. The sound is similar to that of a worn-out record.

I tried restarting the computer but then it defaults to line out again!

By the way I use windows in the same computer and it works fine so I don’t think it’s a hardware issue.

oh and this hasn’t been always like that, I used to have no problems with audio (maybe some update ruined it?)

I already tried

sudo apt-get remove –purge pulseaudio

sudo apt-get remove –purge alsa-base

and reinstalled. I also tried

sudo alsa force-reload

I’m using ubuntu 18.04

fingerprinting – Do emulator programs like Bluestacks, Memu, Genymotion use the real device settings of the computer you’re connecting from?

Many online services use fingerprinting to track users – storing enough hardware and software details to create a unique record.

But what do emulators do? Can they make you completely anonymous on the internet?
Do Bluestacks or Memu use the physical device settings or do they use something else that will help avoid this tracking?

I’m a novice in this world of emulating and I just wish to understand a little bit.

20.04 – No bluetooth earphones as sound input device

My bluetooth earphones, which work completely fine in windows on the same machine, has a problem on Ubuntu 20.04.
After connecting the earphones via bluetooth in Ubuntu, the sound output device sets to the bluetooth earphones, but the sound input doesn’t. In the menu of input devices too, there is only system microphone shown.

Please tell, how to choose bluetooth earphones as sound input device.

I have searched pretty much on the internet, but can’t find a solution.

iphone – How do I stop my AirPods from automatically switching between devices in iOS 14? Or disconnect them from a specific device?

I’ve been having a lot of trouble with the iOS 14 AirPods automatic device switching. I was listening to an audiobook, and then my son started playing a video on an iPad tied to my Apple ID as part of his schooling curriculum and it took over the AirPods.

I switched back on my phone, but then he started playing it again because he hadn’t heard it. He was also turning up the volume, which led to a very uncomfortable experience for me and frustration for him. I’m now afraid to use my AirPods.

I would like to either turn off automatic device switching or disconnect my AirPods from just that device (without them being removed from all the other devices). Is there anything I can do?

Does Find my device feature require internet connection?

I lost my phone in the house, and I was trying out this feature but couldn’t connect to my phone. Why? Does it require Internet connection? If so, this feature doesn’t make much sense…

rom flashing – Can I install a ROM made for a different device?

Short answer:

You can only install ROMs compatible with your device

Longer version

Different Android devices use different hardware, which requires special drivers (e.g. the camera). Those drivers are sometimes/often proprietary (take e.g. Sony, which almost made it into the AOSP project — but had difficulties due to those proprietary parts and thus had to back-out again: AOSP only allows for non-proprietary, Open Source code, like its name suggests: Android Open Source Project). Installing an incompatible ROM, in the best case, makes components of your device unavailable (they are simply not working). In the worst case, you might “brick” it (it won’t even start up).

You might want to check the question Where can I find stock or custom ROMs for my Android device? to find ROMs compatible with your device. Most times, there are several choices available to meet the user’s requirements: Less “bloatware” but more performance, more fancy stuff, custom enhancements… So you still can make your pick.

Turn Android device into a wireless or USB webcam with background removal

There exist several applications such as DroidCam that can turn one’s Android device into a wireless or USB webcam.

Do any of these applications have a background removal feature (= only shows the human face/upper body that appears on the video)? I tried DroidCam but it doesn’t seem to have this feature.
