Is strangely clever enough to somehow quickly cancel whatever the cause of the noiseis (looks like some periodic device polling action), so at least the output is sort of usable, though even for me the 50% DC offset was way too much. However it was surprising that in debian, both on a 2-year old amd64 laptop and a 10-15 year old i386 desktop with stretch, I got this: But it was so bad that even in windows, the DC offset reduced volume range by 50%. I returned this cheapo thing, thinking, hey, if it gives me OK video for even less than many simple headset jack converters, why not. I am not at all picky about the finer aspects of sound, so really "hi fidelity" doesn't matter for me, but the kind of disruptions you describe of course make any sound system quite useless. Thanks for this feedback! It is very interesting, though disappointing to hear That way, I should have a better chance of ordering something that won't need to be returned USBGear USB 2.0 Audio Adapter Box with Line Input and Mic InputĪll show some"evidence" of working with Linux, either from the seller's claims,or reviewer 's reported experience, but having now had to return too many online orders, I was hoping someone hear can tell me of any specific model they know works with their debian (I am still on stretch). Then there is this much more expensive, but much less feature-filled item

Optimal Shop USB 2.0 External Sound Card 6 Channel 5.1 Surround Adapter Audio S/PDIF for PC (Blue) See explanation/conclusion in follow-up post below Which is a really nice box, and while its headphone output works, I am unable to get anything actually coming in through the line-in jack, even though the channel is recognized by alsa.ĮDIT: My bad!!! This device actually works beautifully out of the box. 7.1 USB Sound Card - External Sound Card for Laptop with SPDIF Digital Audio - Sound Card for PC - Silver (ICUSBAUDIO7D) Even if the hardware itself is not junk (which is all too often the case), I have yet to find a device that works in stretch. I am having a hard time finding a way to get simple stereo line-in audio working on USB sound cards.

Then it's just is a question of the sound software finding, and knowing what to do with the various channels on the plugged in "card", so once such a "card" is known to work on a given debian release, it should work the same way on pretty much any other hardware with the same debian release, as long as the sound software is used.
Unless I am horribly mistaken, I don't believe it matters at all what the computer hardware is, as long as it has a USB port that Linux recognizes. This is not a request for help troubleshooting, but simply for any reports of actual successful experience with particular models of USB sound cards.
