I have a Chromebook Pixel 2013 and I know there were problems early on with supporting this device but my understanding was that they were supposedly all ironed out. But I'm still seeing problems. I have this in my /etc/modprobe.d: # cat /etc/modprobe.d/etc-modules-parameters.conf options tpm_tis force=1 interrupts=0 options snd_hda_intel index=1 model=alc283-dac-wcaps And indeed that parameter shows up in the module parameters: # for i in /sys/module/snd_hda_intel/parameters/* ; do echo -n "`basename $i`: " ; cat $i ; done align_buffer_size: -1 bdl_pos_adj: 1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1 beep_mode: Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y enable: Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y,Y enable_msi: -1 id: (null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null) index: 1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1 jackpoll_ms: 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 model: alc283-dac-wcaps,(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null) patch: (null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null) position_fix: -1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1 power_save: 0 power_save_controller: N probe_mask: -1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1 probe_only: 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 single_cmd: N snoop: -1 And it looks like the CA0132 is the first device: # for i in bus/hdaudio/devices//*/chip_name ; do echo -n "$i: "; cat $i ; done bus/hdaudio/devices//hdaudioC1D0/chip_name: CA0132 bus/hdaudio/devices//hdaudioC1D3/chip_name: PantherPoint HDMI But the symptoms I have are: 1) The microphone has never worked 2) In recent kernels (or possibly since I moved that parameter from /etc/modules and it actually took effect) I sometimes get random noise after resuming. Killing pulseaudio fixes that. 3) I get these log messages very frequently -- shouldn't firmware be loaded once when the driver loads and then not again?
