I am using KDE, and I hear a sound > level of 5% the same as 100%. Next time please try reporting 1 issue per bug report. The platform-driver-x86@xxxxxxxxxxxxxxx mailinglist is the right address for the fan issue, but for the sound issue you really should send a separate bug report to the sound/alsa developers. > The second problem is a fan speed. What exactly is the problem with the fan speed ? <snip> > xxx@ga401ih:~/downloads$ ll /sys/class/hwmon/hwmon6/ > total 0 > drwxr-xr-x 3 root root 0 Nov 12 20:33 ./ > drwxr-xr-x 3 root root 0 Nov 12 20:33 ../ > lrwxrwxrwx 1 root root 0 Nov 12 20:34 device -> ../../../asus-nb-wmi/ > -r--r--r-- 1 root root 4096 Nov 12 20:34 fan1_input > -r--r--r-- 1 root root 4096 Nov 12 20:34 fan1_label > -r--r--r-- 1 root root 4096 Nov 12 20:34 name > drwxr-xr-x 2 root root 0 Nov 12 21:30 power/ > -rw-r--r-- 1 root root 4096 Nov 12 21:30 pwm1_enable > lrwxrwxrwx 1 root root 0 Nov 12 21:30 subsystem -> > ../../../../../class/hwmon/ > -rw-r--r-- 1 root root 4096 Nov 12 20:33 uevent Ok, so pwmconfig will not work here because there only is a pwm1_enable file and not a pwm1 file for controlling the actual fan-speed. This is normal on most newer Asus models you can sat the fan to 1 of 2 modes: 1. fullspeed: echo 0 > /sys/class/hwmon/hwmon6/pwm1_enable 2. automatic speed control (the default) echo 2 > /sys/class/hwmon/hwmon6/pwm1_enable Regards, Hans
