The hardware is Toshiba Satellite S50D-A running FC20 with kernel 3.15.6-200.fc20.x86_64. It has analog and HDMI capability, but I am unable to test the HDMI. I have XFCE as my user-interface.

I have no sound from the speakers or the headphones. Using pavucontrol, I have verified that the volume is set at 100%. Using the audio-mixer from XFCE, I have verified that master, headphone and speaker have full volume and are not muted for sound card "HD-Audio Generic (Alsa mixer)", and volume is full with sound card "Playback: Built-in Audio Audio Analog Stereo (PulseAudio MIxer)".

The output from aplay -l is

**** List of PLAYBACK Hardware Devices **** card 0: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]  
Subdevices: 1/1   Subdevice #0:

Sound is working fine under Windows 8.

Does anyone have any idea of how to get sound working?

There is a known workaround for this issue, but it might prevent Windows 8 from booting (if you have a dual-boot setup, depending on whether Windows 8 needs UEFI for secureboot). Basically, by changing the BIOS into "CSM Boot" mode, which seems to be a Legacy style BIOS, Linux is able to use the soundcard properly without any issue:

Hit F2 during power up to get to the BIOS, then go to the Advanced tab. Go to the System Configuration option, then set the Boot Mode to CSM Boot. F10 to save and exit, then reboot and your sound should start working.

It seems like this might be a bug in the BIOS/firmware, so you could also make sure that you've flashed the laptop to the latest version of the BIOS/firmware from Toshiba. Hope that works!

Go into System Settings > Multimedia > Audio and Video Settings and click the Audio Hardware Setup tab. There are 2 pulldown menus under both the Hardware and Device Configuration labels; use these to find the correct settings for your audio hardware.

If this doesn't work, there may be audio device drivers missing.
