I'm running ubuntu on an Apple TV (ATV1). Kernel details are:

Linux atv 3.13.0-45-generic #74-Ubuntu SMP Tue Jan 13 19:37:48 UTC 2015 i686 i686 i686 GNU/Linux

I'm also running alsa, but not pulseaudio. The alsa devices are:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC889A Analog [ALC889A Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC889A Digital [ALC889A Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0

I'm using the ATV1 HDMI output connected to a Sony KDL40EX700 HDTV.

Alsa speaker-test and aplay work correctly, producing sound as expected from the TV speakers.

I have been running XBMC successfully on this setup for several years, progressively upgrading the operating system and the XBMC version. I most recently ran the Ubuntu Gotham release.

However, I have now installed Kodi, and audio output is no longer functioning. I have tried Kodi from the stable and unstable ppa repositories, with the same result in each case.

I have enabled Kodi audio debugging, and rebooted the system with the log shown in

I note the following log entries, which seem significant to me:

It looks like Kodi is trying to open the alsa HDMI sink using device 0, when it should be device 3.

I would appreciate any suggestions as to how to fix this problem.

Thanks,
