Configuration:
- AMD Kabini A4-5350
- TV hooked up to onboard HDMI
In the live disk version of Ubuntu 14.10 x64 HDMI sound output tests as working, and appears as the primary volume in the top right if I mute the other outputs.
After installation this is no longer the case.
All software seems to know about the card and show it running; aplay
, alsamixer
, pavucontrol
, Sound Settings. All software shows output unmuted. No sound actually escapes except the speakers pop when power cycles.
Same problem more-or-less in 14.04. I didn't try sound in the live USB there.
