5 out of 5 eggsawesome little sound card

Pros: F----ing great! this thing needs no driver setup in linux and is picked up in distros automagically as far back as 2009...

Drives LOUD/Clear sound to my sony studio headphones-

Cons: none! works exactly as described.

Other Thoughts: would buy again if this one ever broke...

2 out of 5 eggsDirect comparison

Pros: NONE!

Cons: I did a side by side comparison to the Startech ICUSBAUDIOB 2 channel usb sound card. What a joke! It was not even close. The Diamond was washed out. I have been doing a to b comparisons for 30 years now and many need more then one time to compare as to not make a hasty decision. This was just plain obvious. The Startech uses a C-Media CM108 chipset while the Diamond uses a Via Technologies VT1610 chip set. This has to be the reasoning for my decision. Needless to say the Diamond goes back for return.

Other Thoughts: The 90 degree angle is also stupid as it won't even plug into the back usb ports. I barley got it plugged into the front port.

2 out of 5 eggsCould be better

Pros: works well enough to plug in headphones - simple power speakers (no sub woofer)

Cons: Makes a terrible feedback noise when system is powered down. Need to unplug when power is off to prevent it.

Other Thoughts: on the go, OK. back-up sound card, no way

5 out of 5 eggsThank you Diamond!

Pros: Plug and play - advertises this for all OS's but I have only tried it with Linux and it works well!

Better sound quality than my onboard laptop intel card

Mic in

works fine with USB 1.1 ports (like the ones of keyboard hubs)

Best 30 bucks I have spent in a while!

Cons: I really can't find anything wrong. If you want me to be really picky I would say the thing looks dorky and the light is annoying at night.

Other Thoughts: I bought this because I broke my audio jack by tripping over my headphones. I chose this usb sound card for two reasons:

1. Like the OP said, I love linux and like rewarding manufactures that advertise support for linux as well

2. IT'S CHEEP! - need I say more?

5 out of 5 eggsGood sound, linux friendly

Pros: 1.) mic-in
2.) Good sound quality
3.) advertised as linux compatible(!)

Cons: 1.) The LED is too bright and does an annoying fade-in/out when it is idle.
2.) no optical out (but I knew that when I bought it.)

Other Thoughts: I bought this one because it advertised mac/linux(!) compatibility on the back where the other card I was considering only talked about windows. I'm sure the other card was linux compatible as well, but I like to reward linux-friendly vendors.

While I am not entirely sure I like the form factor (it seems a bit precarious), it has two advantages over alternatives:
1.) it does not interfere with usb ports that are directly to the left/right of it or below it. My other usb soundcard was wide enough and thick enough that it caused problems with anything near it.
2.) it uses a standard mini-usb cable in case you want more length, rather than needing a usb M-F extension cord. I use mini-usb to charge all my cell phones, so I have plenty of them.
