Tascam US-2x2

[marianet]

I have tested a Tascam US-2x2 in a laptop with avlinux, and it works. I can record at 96 Khz.
It uses a USB class compliant driver.

Thanks for sharing, good to know! I'm considering buying this interface, has anyone else had any experience with it?

I'm going to try one in today, so I will be able to share my impression if you are still interesting in it.

I have just bought one. As it described above - it works out of box (debian 8.2 jessie). Sampling rate is 96kHz but sample size is 16 bits and I can't change it using qjackctl. I will write again if solution is found.

I just bought a Tascam US-2x2, as an upgrade from my old Behringer U-Phono UFO202. I was very glad to see it has worked on Debian, as it gave me hope it would also work out-of-the-box on my Ubuntu 14.04.3 LTS ("Trusty"), but alas, no: plugging it in produced no new ALSA sound card entry. Also tried it on my laptop (same Ubuntu version). The Behringer always worked out-of-the-box, so I didn't really know what to try next. I did install alsa-firmware-loaders, but that had no effect that i can see.

Anything any other Linux users can tell me about what I might try to get ALSA to see it on Ubuntu? Thanks!

The output from cat /proc/asound/cards only shows my built-in sound card:

Code: Select all

                      HDA Intel MID at 0xf0600000 irq 28

Here's the output from dmesg :

Recent Debian unstable (May 2017) worked (almost) out of the box. On first connection, dmesg looked like this

After a while, it became alive on it's own.

Similar experience with another device of this type. The other device was working after being connected to a windows machine (to see if it's not broken). Seems like there is something magic about the first power on.
