Trying to get HDMI audio working an Acer X1200 with Nvidia 8200 (driver level 177) and Realtek ALC1200. I've rebuilt and installed the 1.0.18a drivers and the 1.0.18 libs, utils, tools, and plugins from debian experimental. After the upgrade I see the following devices with aplay -l: **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 1: ALC888 Digital [ALC888 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 I looked at /proc/asound/card0/codec#0 and saw that there is a section in there which identifies the digital out of Node 0x11 (17) to be an internal HDMI connection: Node 0x11 [Pin Complex] wcaps 0x400780: Mono Digital Pincap 0x00000014: OUT Detect Pin Default 0x18566140: [Jack] Digital Out at Int HDMI Conn = Digital, Color = Orange DefAssociation = 0x4, Sequence = 0x0 Misc = NO_PRESENCE Pin-ctls: 0x40: OUT Unsolicited: tag=00, enabled=0 Power: setting=D0, actual=D0 Connection: 1 0x10 Mapping this to the output of /proc/asound/devices: 0: [ 0] : control 1: : sequencer 4: [ 0- 0]: hardware dependent 16: [ 0- 0]: digital audio playback 17: [ 0- 1]: digital audio playback 24: [ 0- 0]: digital audio capture 26: [ 0- 2]: digital audio capture 33: : timer Says to me that Node 17, device 0,1, is the HDMI output. Is that correct? I've ensured that in my mixer IEC958 is not muted (set to 00) and IEC958 Default PCM is not muted (set to 00). Using mplayer with "-ao alsa:device=plughw=0.1" or "alsa:device=hw=0.1" doesn't output any sound to my receiver, and using the similar options in MythTV results in the same problem. I've confirmed that this does work with Windows Vista. I'm using version 177 of the nvidia driver. I haven't see any kind of configuration specific for the nvidia driver - does anyone know if there is something we need to do there? (modinfo nvidia doesn't list any obvious parameters). -- Darren Hart ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
