A new face on old content. 

Now I’m a great fan of MythTV; and I think that it is a fantastic media frontend providing LiveTV functionality as well as media sharing and many other great things. 

But dissapointment comes from the fact that after years this Open Source project is still sat at 0.21. Version 0.21 is a great and stable release; but there are many things that MythTV still needs to do. I wish; selfishly that more people would put more time into developing for MythTV!

If only I had developled my programming skills I would help. However I didn’t; therefore I cannot!

    Well, it took me some time – so I figured that I would write up the details; so that when I rebuild my HTPC or just in case anyone else is having the same issues!

    Firstly; I have MythTV 0.21 running on a Shuttle XPS SG33G5M with Ubuntu 8.10

    I have my TV connected by HDMI from the Shuttle – however never been able to get my audio through the HDMI, so always had to run a phono cable from the rear of the Shuttle to separate speakers.

    My devices were reported as:

    david@Rosy:~$ aplay -l
    **** List of PLAYBACK Hardware Devices ****
    card 0: Intel [HDA Intel], device 0: ALC888 Analog [ALC888 Analog]

    card 0: Intel [HDA Intel], device 3: ATI HDMI [ATI HDMI]
    Subdevices: 0/1

    … and my outputs shown as …


    david@Rosy:~$ aplay -L

    Firstly my version of ALSA was not the latest …

    david@Rosy:~$ cat /proc/asound/version
    Advanced Linux Sound Architecture Driver Version 1.0.17a.
    After failing to download and install the latest ALSA drivers from http://www.alsa-project.org/ I stubbled across a fantastic script which did it all for me. This Alsa 1.0.18 Installation Script (http://ubuntuforums.org/showthread.php?t=962695) automatically download, compiles, installs and configures ALSA 1.0.18a for you. God bless Google and the Open Source world!
    Once this was completed a quick confirmed that I could pass audio through the HDMI cable to the TV …

    david@Rosy:~$ speaker-test -Dplughw:0,3 -c2
    speaker-test 1.0.18
    Playback device is plughw:0,3
    Stream parameters are 48000Hz, S16_LE, 2 channels
    Using 16 octaves of pink noise
    Rate set to 48000Hz (requested 48000Hz)
    Buffer size range from 64 to 16384
    Period size range from 32 to 8192
    Using max buffer size 16384
    Periods = 4
    was set period_size = 4096
    was set buffer_size = 16384
     0 – Front Left
     1 – Front Right
    Now I turned my attention to MythTV and in Setup->Gerneral under the Audio Tab I configured my settings to:

    Ouput Audio Device: ALSA:plughw:0,3
    Passthrough output device: ALSA:plughw:0,3
    Max Audio Channels: 5.1
    Upmix: Passive
    Enable AC3 to SPDIF passthrough: on
    Enable DTS to SPDIF passthrough: on
    Mixer Device: ALSA:default
    Mixer Controls: Master
    This then configured my MythTV frontend to pass all the audio straight through to the HDMI cable going to the TV – result!

    This seemed fine – providing that whatever media I was watching/listening to was using MythTV internal commands. However as I was using a bespoke mplayer configuration anything that was played using it passed the audio back to the phono output and not the HDMI.
    So, I under the Setup->Media Settings->Video Settings->Player Settings I modified …


    Default Video Player: mplayer -vo xv -ao alsa:device=hw=0.3 -autoq 1oo -vf pp -fs -zoom %s

    and then made sure that any video file type (avi, mpg etc) was set to use the Default Video Player and not the Internal one.
    Result!!!
