Hi,

I am using the latest Debian release and I can't seem to get HDMI audio to work. There is no speaker icon in the system tray. I have tried adding hdmi.audio=EDID:0 to /boot/uEnv.txt.

aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: sunxicodec [sunxi-CODEC], device 0: M1 PCM [sunxi PCM]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 1: sunxisndhdmi [sunxi-sndhdmi], device 0: SUNXI-HDMIAUDIO sndhdmi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0



aplay -L
null
    Discard all samples (playback) or generate zero samples (capture)
sysdefault:CARD=sunxicodec
    sunxi-CODEC, sunxi PCM
    Default Audio Device
sysdefault:CARD=sunxisndhdmi
    sunxi-sndhdmi,
    Default Audio Device


If I use alsamixer and try and select the correct sound output I get the message:
"This sound device does not have any controls."

Could somebody tell me how to get this to work?

Thanks

After messing around with various files the HDMI sound has decided to start working. I have no idea what made it start working.
