HDMI output used to work fine on my Samsung NP300E5C laptop in Ubuntu 12.04. However, I did a reinstall with the new 13.04 release (64 bit), and now I don't see the HDMI output as a choice in the Sound Settings.
The aplay -l
command returns the following:
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
This means that the device is found, but can't be used, as can be seen when I input speaker-test -c 2 -r 48000 -D hw:0,3
:
speaker-test 1.0.25
Playback device is hw:0,3
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Playback open error: -19,No such device
Also, alsamixer
doesn't show sliders related to the HDMI output. What do?
