I recently installed Ubuntu 19.10, wiping Windows 10, and my internal microphone isn’t working. I tried installing Pulse Audio, alsamixer and there there is no internal mic being detected.
Input settings screenshot
However, when I connect a headphone with mic, it works fine. I also tried to add few combinations under /etc/modprobe.d/alsa-base.conf file, following few blogs, unsuccessfully.
alias snd-card-0 snd-hda-intel options snd-hda-intel model=auto
I tried things from the below link as well but unfortunately didn’t work
Under alsamixer the card is HDA Intel PCH and Chip is Realtek ALC3204
Note: My Laptop config is like this
Any and all kind of help is appreciated.
Thanks in advance.
PS: I am a newbie, who has just started to learn and my first step was to install the OS.
I am trying to model a load balancer as a queueing network.
The load balancer has a number $ n$ of internal threads. There is a central queue of requests from which the threads are fed. Each thread can handle one request at a time: It parses it, forwards it to one of 3 servers, and waits for the response, then sends the response back.
The servers themselves process requests sequentially. Therefore, I think the servers should be modelled as something similar to a M/M/3 queue.
On the other hand, the internal threads should be modelled as a M/M/n queue.
The central issue is that the threads are blocking while they wait for the response from the servers. Therefore we cannot simply model the server queue to be sequentially connected to the thread queue.
What I would need is some kind of way to model a queue M/M/3 inside and shared between the service providers of a M/M/n queue.
Is there a way to do this in queueing networks, and if no, how would you work around this issue?
From a InfoSec perspective which is best for private (on-premise) micro-services (web services) accessed via HTTPS?
Is there an advantage in using regular certificates over self-signed in such a scenario?
I have created a person or group column in list. When I take list template and use it in other site the internal name of the person or group column gets changed. I have used the internal names of this column in my code. Now due to this mismatch of internal names the code is failing.
On item create, the workflow goes into suspended mode with the following information:
Details: An unhandled exception occurred during the execution of the workflow instance.
Exception details: System.IO.InvalidDataException: Unable to deserialize HTTP response content. Expected ContentType : ‘application/json’, ‘text/plain’ or ‘text/html’, Received ContentType : ‘text/html’. Content (truncated) : ”.

The internal microphone does not work.
What could be the reason?
How can I check if I have the correct driver?
How can I verify if I have a driver at all?
I have installed ubuntu 18.04.3 LTS in my system 3 months ago. After 2 months, I don’t have the read and write permission on any internal drive except my system drive. I have used chmod -R 777 * in all 4 internal drives. Still I am not able to get the write permission. Every time I use chmod -R 777 *, It sets read only permission to every file.
That’s the console output I am getting.
chmod: changing permissions of ‘filename.jpg’: Read-only file system
chmod: changing permissions of ‘filename.mp4’: Read-only file system
Can someone explain Ubuntu internal working process and files even root user also can’t access. Is there any good book or website,I just want to know about Ubuntu?Linux related concepts?
I recently installed Ubuntu 18.04 about two days ago and I just boot the system only to see this: Error Description
