G'day, I've a laptop on my lab bench with a Realtek ALC5645 codec attached to an Intel(R) Atom(TM) x5-Z8350. Built-in speakers work properly. Not working are; - headphones; only ever silent playback, - built-in microphone; only ever silent recording, - headset microphone; only ever silent recording, - there is no response to headset jack insertion or removal, It has never worked. http://www.alsa-project.org/db/?f=f14914c88544d57f736ed6623000957c93bc4612 http://dev.laptop.org/~quozl/z/1dCw32.txt dmesg http://dev.laptop.org/~quozl/z/1dD2qx.txt dmidecode http://dev.laptop.org/~quozl/z/1dGJdK.txt dsdt.dsl I'm testing with 4.11.1 kernel on Ubuntu 17.04. I've tried latest UCM/chtrt5645/HiFi.conf c8b344c. I've tried using alsamixer to experiment with some of the 253 or so controls. I don't have a datasheet. (My previous work was with ALC5631, for which I do have a datasheet, and it was very helpful!) Also in the box was an NTC thermistor cabled to a TRRS plug, which may suggest a design with switchable decoupling capacitors. -- James Cameron http://quozl.netrek.org/ _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
