Doesn't this happen when you unload the device, right?
These errors "snd: bad kfree" also happen when unload and reload the driver
rmmod snd-hda-intel insmod snd-hda-inteel
And, it happens when writing to /sys/class/sound/hwC0D0/clear?
Is "HD-Audio reconfiguration" still experimental ?
Somehow yet, but mostly it worked for me :)
I just use hda reconfig to change the model="auto" to "6stack-dig-fp" and vice versa
This mean that I need to implement "Independent HP" switch which allow user to change the topology if this feature is still experimental
ALSA hda_hwdep.c:220: hda-codec: reconfiguring snd: bad kfree (called from f8be4636)
Hmm, this is a magic check in external alsa-driver builds. I guess it's just a bug there -- the override of krealloc() is missing.
Does the patch below (to alsa-driver tree) fix the problem?
Do I need to specify any option and run configure script again ?
alsa-driver compiled without error but fail to loaded and complain ksize undefined symbol
