I'm not using Nvidia GPU, the rendering is done on the integrated GPU. When I connect the laptop to a Panasonic Vega TV through HDMI I get video output on the TV but no sound. I have selected the HDMI output in pavucontrol (the HDMI output is marked as "plugged in" there) and I can see the sound is directed to HDMI. I also tried to disable pulseaudio and use aplay to test ALSA output but there is still no sound. 'aplay -l' output: **** List of PLAYBACK Hardware Devices **** card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: PCH [HDA Intel PCH], device 0: ALC668 Analog [ALC668 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 For all card 0 devices I tried this command line: aplay -D plughw:0,N /usr/share/sounds/alsa/Front_Right.wav and got no sound nor errors. I remember the sound was working at some point (I think 13.10 was installed at that time). lsb_release -rd Description: Ubuntu 14.04 LTS Release: 14.04 --- ApportVersion: 2.14.1-0ubuntu3.3 Architecture: amd64 CurrentDesktop: KDE DistroRelease: Ubuntu 14.04 InstallationDate: Installed on 2013-10-11 (304 days ago) InstallationMedia: Kubuntu 13.04 "Raring Ringtail" - Release amd64 (20130424) Package: alsa-driver (not installed) ProcVersionSignature: Ubuntu 3.13.0-33.58-generic 3.13.11.4 Tags: trusty Uname: Linux 3.13.0-33-generic x86_64 UpgradeStatus: Upgraded to trusty on 2014-05-02 (101 days ago) UserGroups: adm bluetooth cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 09/17/2013 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: N550JV.207 dmi.board.asset.tag: ATN12345678901234567 dmi.board.name: N550JV dmi.board.vendor: ASUSTeK COMPUTER INC. dmi.board.version: 1.0 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: ASUSTeK COMPUTER INC. dmi.chassis.version: 1.0 dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrN550JV.207:bd09/17/2013:svnASUSTeKCOMPUTERINC.:pnN550JV:pvr1.0:rvnASUSTeKCOMPUTERINC.:rnN550JV:rvr1.0:cvnASUSTeKCOMPUTERINC.:ct10:cvr1.0: dmi.product.name: N550JV dmi.product.version: 1.0 dmi.sys.vendor: ASUSTeK COMPUTER INC.
