I know this question has been asked a million times, but none of the things I've tried from other answers have worked. I've got a Caicos HDMI Audio [Radeon HD 6400 Series] audio device and I've installed "PulseAudio Volume Control" after reading this thread https://askubuntu.com/a/232407/45985 and I can see "Radeon HD 6400" listed in the output devices and see the volume meter moving when I try to playback audio, but nothing comes through the speakers.
aplay -l outputs:
**** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: VT1708S Analog [VT1708S Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: SB [HDA ATI SB], device 3: VT1708S Digital [VT1708S Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0
I can also see the "output bar" moving as if it were playing audio, but still no sound from the speakers...
Thanks in advance,
