I bought this to use with a laptop which had a broken headphone port, mostly because of how small the interface is.
For playback purposes i had no real complaints apart from the lack of a volume control, not a problem in my case.
For recording however i struggled to get a loud enough microphone signal on my interface no matter how much i boosted the signal. Im guessing this is a linux issue and not having an available driver for it means im kinda screwed.
I wont be using this interface for recording so its not really important to me but thought i would mention it in case you do run a linux os.
It does what i need it to so will be keeping it, its a nice portable interface
