I was trying to output video and sound to my TV over HDMI.
According to the ALSA wiki page the sound was outputed to my TV with playcommand
% aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: SB [HDA ATI SB], device 0: CONEXANT Analog [CONEXANT Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
% aplay -D plughw:0,3 /usr/share/sounds/ekiga/newmessage.wav
However when I tried the script in the wiki to detect hot plug cable, my system reported that there is no
/sys/class/drm/card0-HDMI-A-1/status
In "/sys/class" there is no "drm" directory
How can I detect if the HDMI cable is plugged in ?
Offline
What happens when you run this command,
udevadm monitor
and then plug and unplug the HDMI cable?
Offline
I tried 2-3 times plugging and unpluggin, nothing
% sudo udevadm monitor
Password:
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

That's weird that udev doesn't detect the plug/unplug events.
What do you get from these commands?
lspci -nnmvk | grep -B1 -A8 -i audio
lsmod
Offline
Oh, i found out why: it's because i'm using catalyst and not radeon driver. When I switch to radeon, then there is a drm directory in /sys/class.
However the question still remains: how do i detect the status of HDMI port, given that i use catalyst? Because my netbook has an AMD Evergreen GPU (AMD E-350), and according to the Radeon feature page, HDMI audio is not available until kernel 3.3
Otherwise what is this drm directory ?

I've restarted my PC and this is the second time after installing an NVidia driver my resolution is off. All that shows is the wallpaper and my mouse goes off the screen, to the left and my pointer stops mid screen.
I'm trying to resize my screen via command line Ctrl+Alt+F1
$ xrandr
Can't open display
