I was keeping track of where I was at with Myth on my home wiki, but then figured I might as well share it here!
Contents
My Setup
MythBuntu 9.10 with separated front-end/backend
- Live TV/TV recording Free to air HD/SD (from Sydney, Australia)
- Multi-rec
- DTS/AC3 passthrough including 5,1 surround digital out
- VDPAU
- MythMusic
- MythGallery
- MythVideo
- Suspend + Wake On USB
Backend
Hardware
- HDDs totalling 1.2Tb
- Intel S775 Core 2 Q6600 Quad-Core CPU
- Gigabyte S775 GA-G33M-S2 Motherboard
- 4GB RAM
- DNTVLive LP Tuner
- PCI Hauppauge Nova-T-500 MCE(OEM) Dual DVBT tuner
Software
- Ubuntu 9.10 64bit
- MythWeb on Jetty rather than apache including the WAP version on the BlackBerry!
- Shepherd XMLTV grabber
- NFS server for music/images
- TFTP server for MiniMyth
Configuration
- DVICO used device id 17de:a8a6 for two distinct devices requiring different drivers. Need to set "options cx88xx card=19" in /etc/modprobe.d to force use of Conexant reference drivers. Fortunately the Hauppauge tuner is a USB device so we can override the auto detection rather than patch the v4l dvb drivers to override it.
Frontend
Hardware
- ZOTAC ionitx-d-e board, 2G memory
- Szrealan E-2011 case (tiny!)
- External DVD player
- 1Tb external e-Sata drive
- BenQ PE8700 DLP Projector
- Samsung LCD Television
- CambridgeAudio AV receiver
- MCE Remote
Software
- MythBuntu 9.10 64bit
- Synergy to allow laptop to be the keyboard/mouse.
Configuration
Enable Wake on USB
We need to enable USB0 in /proc/acpi/wakeup
Note if USB2 is also enabled, then the board immediately wakes up regardless, unsure if this is due to another USB device
/etc/rc.local
/usr/local/bin/set_wakeup.sh
/usr/local/bin/set_wakeup.sh
#!/bin/sh #set wake via remote WAKEUP="" if [ -f /etc/default/wakeup ] ; then . /etc/default/wakeup fi for device in $WAKEUP do enabled=`cat /proc/acpi/wakeup | grep "$device" | awk {'print $3}'` if [ "$enabled" != "enabled" ] then logger -t "wakeup" "Enabling wakeup for $device" echo "$device" > /proc/acpi/wakeup fi enabled=`cat /proc/acpi/wakeup | grep "$device" | awk {'print $3}'` logger -t "wakeup" "$device $enabled" done
/etc/default/wakeup
WAKEUP="USB0"
Auto-start X Server
- disabled GDM in /etc/X11/default-display-manager
- Simple mingetty startup with a tty definition and a startx script in the console
- user .xsession linked to /usr/share/mythbuntu/session.sh so we get the same xfce startup.
/etc/init/tty7.conf
# tty7 - mingetty for MythTv # # This service maintains a mingetty on tty7 from the point the system is # started until it is shut down again. start on runlevel 2 stop on runlevel 0 stop on runlevel 1 stop on runlevel 4 stop on runlevel 5 stop on runlevel 6 respawn exec /sbin/mingetty --autologin=<user> tty7
~mythtv/.profile
Appended to detect if we are on tty7, in which case we start-up X with an optional layout specified in ~/.mythrc
Note that when X is stopped we automatically logout and respawn
start-frontend() { MYTHRC="$HOME/.mythrc" if [ -r $MYTHRC ] ; then . $MYTHRC fi LAYOUT_SPEC= [ ! -z "$LAYOUT" ] && LAYOUT_SPEC="-layout $LAYOUT" startx -- $LAYOUT_SPEC -logverbose 5 logout } tty | grep tty7 && start-frontend
xorg.conf
For PE8700 Samsung LCD. See also the tips for the NVidiaProprietaryDriver
The FX5200 cards were the cause of my DVI problems on my projector. Apparently they freak out a PCB component causing the EDID data to become corrupt. (a Gigabyte card lasted from Aug 2006 to Dec 2007. Fortunately the new nvidia driver allow you to use a CustomEDID to load the data from a file.
Option ExactModeTimingsDVI is also important for the projector.
Option "UseEDIDDpi" "false" or some equivalent control of DPI is important for the Samsung television otherwise you get really small fonts (fixed in 0.21)
There are two layouts, the default uses outputs via VGA to a Samsung LCD television, the second uses DVI to the PE8700 projector.

~mythtv/.mythtv/session
Start a ruby program that listens to /dev/lircd and manages -
- mythtv via updating the database + network control port
- the AV receiver via RS232 - volume/mute, power on/off, input type
- alsa via calls to amixer - volume/mute, digital/analog outputs
- suspend on lirc idle or power button
- restart specifying TV or Projector layout
#!/bin/sh #store our dbus session and display where our kill script can pick it up export | egrep "DBUS_SESSION_BUS_ADDRESS|DISPLAY" > ~/.xsession-export #Run unclutter to hide the cursor after resume - not required - see HWCursor in xorg.conf #unclutter -display $DISPLAY & #run our main lirc control program /home/mythtv/bin/audiomodeswitch/main.rb &

~mythtv/bin/kill_mythtv.sh
Script is called by the ruby program, but also useful to restart from ssh

LIRC Remote Control
Standard mythbuntu setup for MCE remote.
Sound
Onboard sound
~/.asoundrc
Could probably do better 48/44kHz switching on the analog output between music and video but if that is important we just go digital passthrough and let the receiver do the work.
In myth config, you can see that default sound device is ALSA:myth-video, the passthrough device is ALSA:myth-passthru, and mythmusic uses ALSA:myth-music. the AC3PassThru and DTSPassThru settings are managed by the ruby program
#First line comment pcm.myth-music { type copy slave.pcm "default" } ctl.myth-music { type hw card 0 } pcm.myth-video { type copy slave.pcm "default" } ctl.myth-video { type hw card 0 } pcm.myth-passthru { type copy slave.pcm = "spdif" } ctl.myth-passthru { type hw card 0 }
minimyth.conf
TODO - Works nicely through the WRT310N router etc, but we have a hard drive have decided to stick with Mythbuntu for now.
