[alsa-devel] External sound card issue
Hi,
I have just bought an external sound card: Asus Xonar U7
I typed in terminal:
alsamixer
Then I wanted to change the sound card (I have connected an external sound card via USB).
I pressed F6, selected the external sound card and pressed enter.
alsamixer crashed and outputed:
cannot load mixer controls: Broken pipe
My ALSA information is located at http://www.alsa-project.org/db/?f=1871c086b58a2965d18cfb38483794788187edfb
Please see this bug reported in alsa-driver package: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1267866
Tell me what other information you need.
Can you fix this bug in 7 days? If you cannot I will return the sound card to the shop.... :-(
Thank you! Good luck!
I wait for your answer,
Ionica Bizau

This looks like a bug in the device's firmware.
Can you at least read the list of controls ("amixer -c1 controls")? Are there some controls that you are able to access (try "amixer -c1 cget name='xxx'" for each one)?

Hi Clemens and Raymond,
First of all please tell me if this can be fixed. I can be patient and wait until you fix it but if it's not possible I will return the external audio card to the shop.

The device's firmware does not allow reading this mixer control for some reason; this is probably a bug.
Please try the following commands: rmmod snd-usb-audio modprobe snd-usb-audio ignore_ctl_error=1
This makes the driver ignore errors, but cannot prevent the errors from happening in the first place. Please check if you get the desired effect when you write this control.

I will try them. Is this a bug in the hardware device or in the Linux driver? If this is in the Linux driver, can this be fixed?

We have tons of workarounds in the driver for such broken devices. This will be just yet another one.

Somebody recommended me to run this:
arecord -f cd -D hw:1,1 | tee recording.wav | aplay
This records the sounds from piano and outputs them to headphones but with a delay of 1, 2 seconds.
Do you have any idea about how can be fixed this delay...?

Exit all programs (such as PulseAudio) that might be using the device.
Alternatively, add the line
options snd-usb-audio ignore_ctl_error=1
to some .conf file in /etc/modprobe.d/, and reboot.

I have the successor to that card ("Xonar U7 Echelon Ed."), with similar issues.
Bus 004 Device 009: ID 1043:85c1 iCreate Technologies Corp.
Incidentally, the capture selector switch seems horribly broken even in Windows! In my attempts to get line-in and mic-in working, I've gotten the audio driver (or perhaps the device?) wedged several times.
Side note: alsa-info.sh did not catch the following non-prefixed message: [ 1612.517217] cannot get ctl value: req = 0x81, wValue = 0x0, wIndex = 0x1400, type = 3
The device works relatively well with ignore_ctl_err=1 set.

Incidentally, the capture selector switch seems horribly broken even in Windows! In my attempts to get line-in and mic-in working, I've gotten the audio driver (or perhaps the device?) wedged several times.
Correction: It seems my hangs may be a red herring, due to using the device on a USB 3.0 controller.
Anyway, if we get a fix committed for this device, it should probably include both device IDs.
