You need to prepare a "patch" firmware file. It's a text file containing the workaround for your device. It looks like: ================================================================ [codec] 0x12345678 0xabcd1234 2 [pincfg] 0x15 0x411111f0 0x16 0x411111f0 0x17 0x411111f0 ================================================================ where you need to fill the right values to the first three numbers after "[codec]" line. The first value is the codec id, check "Vendor Id" in /proc/asound/card0/codec#0. The next one is the subsystem id, corresponding to "Subsystem Id" in the codec file. The last one is the codec address, again, "Address" in the codec file. The rest are overrides of the pin configuration. You can use the values above. It means to disable pins 0x15, 0x16 and 0x17. Then save it to a file in the firmware directory, e.g. /lib/firmware/alsa/myfix. Then pass it via patch module option of snd-hda-intel. For example, create a /etc/modprobe.d/* file (e.g. /etc/modprobe.d/50-alsa.conf), which contains only a single line options snd-hda-intel patch=alsa/myfix Takashi ------------------------------------------------------------------------------ Master Java SE, Java EE, Eclipse, Spring, Hibernate, JavaScript, jQuery and much more.
