There have been input related fixes to chtrt5645's UCM config recently. This is the latest version:http://git.alsa-project.org/?p=alsa-lib.git;a=blob_plain;f=src/conf/ucm/chtrt5645/HiFi.conf;hb=HEAD Try copying that to /usr/share/alsa/ucm/chtrt5645/HiFi.conf -- Tanu I tried this fix, after substitute HiFI.conf file and reboot the laptop, sound configuration options changed, output sound still working, but input NOT. Something else to do ? Thanks. -------------- next part -------------- An HTML attachment was scrubbed...
