Solved: How to disable snd-usb-audio?

idata · ‎05-16-2016

Hello. I have a usb web camera Microsoft LifeCam Studio. This one has an audio problem with linux, but if I add the string "blacklist snd-usb-audio" into the blacklist.conf file then the problem with "frequency 0x82" is vanished. But AFAIK Edison kernel has builtin snd-usb-audio. Therefore it cannot be disabled by blacklist or rmmod command.

Please help me to stop this module.

Thanks in advance.

Hi DufeRob,

Did you test it with the Edison board or with another Linux PC? Given that snd-usb-audio is builtin in the Linux kernel you'll need to deactivate from the kernel directly. I would suggest you to check chapter 5 of the Edison Board Support Package, http://download.intel.com/support/edison/sb/edisonbsp_ug_331188005.pdf http://download.intel.com/support/edison/sb/edisonbsp_ug_331188005.pdf, Customizing the Linux* Kernel. You'll find a quick explanation on how to make modifications to the kernel. In summary, you'll need to open the Linux kernel Configuration and search for the module to disable it. Make sure to save a copy of the default configuration in case you need to get back to the original file.

Regards,

Pablo
