The loopback device is a special, virtual network interface that your computer uses to communicate with itself. It is used mainly for diagnostics and troubleshooting, and to connect to servers running on the local machine. The Purpose of Loopback When a network interface is disconnected--for example, when an Ethernet port is unplugged or Wi-Fi is turned off or not associated with an access ...
127.0.0.1 is the loopback address, commonly known as localhost, which is the name that resolves to it by the local hosts file. This file is in different locations depending on the OS, but in most Linux distros it is in /etc/hosts.
loopback loop (hd0,gpt2)/ubuntu-19.10-desktop-amd64.iso ...grub hangs, there is no more output or activity on the terminal, and eventually the laptop fans spin up because the laptop gets hot.
The two are on different "interfaces" - the lookback address is on the loopback interface which should be present always (unless you've done something really freaky with your config). The local IP address is on one of your other network interfaces. If that interface didn't come up, then that ping will fail but the loopback IP should still work.
Thus all the loopback devices created inside the grub are invisible to kernel. The kernel will reinitiate everything like it sees them the first time. The squash mount happens inside the kernel. At this time kernel can see the actual iso file on the real disk. It can mount the iso file and unpack the squashfs then.
I think it is not possible this way (using the loopback module). According to the module description, this "allows one to route audio from a source directly back to a sink". But what you need is routing a sink or a different source to another source (microphone).
