Hi Hans, >I assume that when you say there is no input sound, you mean that the > microphone build into the laptop is not working ? That's right. I tried your suggestions, substitute HiFi.conf file and add these kernel command line parameters. And the mic, still desn't works. I tried also dmic on 1st and 2nd input. There is something that catches my attention. Always after did a change, I go to Gnome sound settings, input tab, and the only device showed is chtrt5645 Analog Stereo. I expected see a digital device... i don't know. Are there something more to do ? Thanks in advance.
