I plan to buy ASUS Xonar U7 USB sound card but don't see drivers for Linux in the ASUS site. I don't see it in the ALSA supported cards page either (http://www.alsa-project.org/main/index.php/Matrix:Vendor-Asus). Does anyone know whether its supported in Linux?

I tried the Xonar U7 on Mint 16 (based on Ubuntu 13.10) and it works fine (I haven't tried multi-channel though). Absolutely no noise, the sound is perfect with alsa k3.11.0-12-generic, alsamixer v1.0.27.1 and pulseaudio 4.0.

On 29th January the alsa-wiki page provided in the first post was updated, and now the Xonar U7 is supported. With the alsamixer is also possible to change the gain setting.

To fix the broken pipe error, add options snd-usb-audio ignore_ctl_error=1 at the end of alsa-base.conf:

sudo gedit /etc/modprobe.d/alsa-base.conf

add options snd-usb-audio ignore_ctl_error=1, save and close. 

alsa force-reload

then

alsamixer

press F6 and select "Xonar U7", now you can change the "Speaker Front" value to increase/decrease the headphone output gain.

To make the Xonar U7 analogic multichannel playback fully work on lubuntu, you need to do the following:

  1. in file /etc/modprobe.d/alsa-base.conf, change the line

    options snd-usb-audio index=-2

    to

    options snd-usb-audio index=0

    in order to set the U7 as your default sound card.

  2. In home file ~/.config/openbox/lubuntu-rc.xml set the volume keys with amixer lines such as:

     XF86AudioRaiseVolume:     amixer -c 0 sset Speaker 3+ unmute
 XF86AudioLowerVolume:     amixer -c 0 sset Speaker 3- unmute
 XF86AudioMute:            amixer -c 0 sset Speaker toggle

    using the 'Speaker' control

Hope this will help :-)

It works perfectly in Ubuntu with ALSA, but only with the minimum gain setting (I can't figure out how to change the default gain setting). BTW, this card has the lowest noise I ever seen: it's practically noiseless!

The U7 soundcard is supported, yet I've noticed on my PC that the multimedia keys (configured to use amixer) to raise or lower the volume don't work as they do with my internal xonar DX. I wonder if it's a conflict with this one already installed in my pc which (unlikely) could be resolved by removing or disabling the DX...

I have one, it works, but it's not something you should look forward to. Very loud, very noisy. It works out of the box though, but yeah, if you're looking for better quality sound, I would say get something that's not ubuntu or become software developer to make your own drivers.
