Review of Linux Compatibility

The Asus Xonar U7 is an external USB sound card, which bases on the CM6632A chipset. It has the USB ID 1043:857c:

Bus 001 Device 002: ID 1043:857c iCreate Technologies Corp.

The Xonar U7 is fully supported by Linux’ ALSA driver using the snd-usb-audio kernel module. However, an additional configuration of a module option might be necessary, depending on the default configuration of the used Linux distribution. The following kernel option has to be set in /etc/modprobe.d/alsa-base.conf:

options snd-usb-audio ignore_ctl_error=1

After changing the alsa-base.conf file the new configuration can be activated by

alsa force-reload

Afterwards, the Asus Xonar U7 soundcard should be fully functional under Linux:

    I think Asus That Should Develop a driver That soon runs on Linux for Xonar U7. As well as other brands With Their Products

    If you want to make sales, That They Should be aware more and more people use Linux as the primary operating system.

    In Linux Mint does not work the line 17.2 snd-usb-audio ignore_ctl_error = 1. Still showing broken pipe. The sound is pretty weak.

    Instead Windows is perfect.

    I hope That the GNU / Linux community with a prompt solution. I doubt that Asus do something about it.

      Hello John,

      Could you please provide us the relevant output of “dmesg”? Are there any error messages regarding the Asus Xonar U7 provided by dmesg?
      What is your output of

      cat /proc/asound/devices

      Thanks!

      Strange, because your output is showing a capture device: “digital audio capture”.

      Is the command “arecord -l” showing any devices? Something like

      **** List of CAPTURE Hardware Devices ****
      card 0: U7 [Xonar U7], device 1: USB Audio [USB Audio #1]
      Subdevices: 1/1
      Subdevice #0: subdevice #0

      Did you try to unmute and set the micorphone volume with “alsamixer” or other mixer tools?
      “Front Mi” and/or “Mic” should be set to a certain level (see screenshot).
