USB audio adapter
 

I have broken audio output jack of my laptop so sound is coming out only of one speaker,
My plan is to buy usb audio adapter,

Could you guys share your experience:

1. Which adapters are working correctly under linux and are easy to install(doesn't ask 1-2 days of searching and getting it to work)?

2. How do they work? Is there some application which is working in background, converting and sending information to USB port?

3. Could you tell if these adapters are working correctly and doesn't have some issues I should keep in mind?

4. Any other things I should know about these adapters in general and their connectivity to computers(laptops) and OS(Linux)?

Hi there,

since I gave you the hint, let me say a few words about that. I don't have much experience of my own, I rather know these devices from ads and IT retailers. As usual, Windows is given more attention by the manufacturers, so Linux compatibility is an issue. On the other hand, these units are often recommended for use with headsets and IP telephony (i.g. with Skype), and that is not limited to Windows, of course.

As I said, I have no experience of my own about item 1.
Item 2 is more technical, so I can step in there: They are "perfectly normal" sound cards, only the host system communicates with them via USB instead of PCI bus. Since Linux isn't picky about the way it has to use for communicating with a device, I don't expect much of a problem with installation.
Bear in mind that the price is to a certain extent related to quality, so don't expect superior sound quality from a $10 device.

Connectivity may be an issue - they usually have only two jacks, instead of three like most PCI or on-board sound cards. One is Line-Out, the other can be configured as Line-In or Microphone-In, but not both at the same time.

When you buy such a device, make sure you have the chance to return it in case it shouldn't work with your system.

Thank you for the advices, all the time I was thinking, but how the hell will line out convert analogue into digital and then back to analogue signal, of course I was making things more complicated in my head, obvious it's sound card connected through USB dough :D

If anybody has experience with actually using devices, it will be appreciated!

I just happen to use a live 6 and it works on some distros by default. Why not do a web search for linux and the few products you are considering?
