| Post subject: | ::: SOLVED Digital audio problems R7.4::: |
I had Digital audio working under 6.04 and now I can't get it to work in R7.4. It's an ACER E360 Motherboard. Using the onboard audio. Audio info listed in the manual as Controller: MCP51 Codec: Realtek ALC850 (7.1 channel audio support) UAJ support (HD audio feature suppport on rear only) The spdif (IEC 958) shows up under Settings>General>MythTV>audio but doesn't work. Under Settings>LinHES>Audio I can only see the Nvidia HDMI audio output Alsaconf doesn't see it either only the Nvidia. Aplay -l Code: aplay -l **** List of PLAYBACK Hardware Devices **** card 0: ICH [Intel ICH], device 0: Intel ICH [Intel ICH] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: ICH [Intel ICH], device 2: Intel ICH - IEC958 [Intel ICH - IEC958] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 The SAF is still OK since I have audio working over HDMI to the TV. MyAF is low since my amp only has SPDIF in and not HDMI. Thanks for your help. |

I booted into Ubuntu on the same machine and the audio was working. Only analog stereo over SPDIF, and audio over HDMI was working. I tried changing it to 5.1 and the audio starts pulsing. Here is a video of what I found in Ubuntu. Sorry that the volume of the TV is a little too quiet at times. http://youtu.be/8ElyNsNMsJE |

OK I figured it out. I'm not sure where or why it went wrong But I can tell you what works. I found someone somewhere on some forum mention that the IEC 985 needs to be set to 0. After reading this I dismissed it and kept looking and forgot about it. Then I remembered and tried it and Voila Alsa Defalut IEC works perfectly here is a small description http://alsa.opensrc.org/Realtek_ALC650#SPDIF_support |
