Thread: MythTV HDMI Sound Problems

-

i have motherboard integrated nvidia hdmi output both video , sound htpc. of mythtv wiki , other forums, managed sound working through hdmi output (outside of mythtv). thing have sound working enable switch "iec958 1", or run command
code:
amixer set iec958,1 on
after that, sound works fine.

now, i'm trying working in mythtv , having problems.
i've tried using allen's digital audio howto (allensdigitalaudiohowto - mythtv).

i've tried setting /etc/asound.conf of suggestions, haven't been successful yet. hdmi card 0, device 3, got following command work:
code:
mplayer -ao alsa:device=hw=0.3 -afm hwac3 test.mp3

mythtv settings follows:
code:
audio output device: alsa:default  passthrough output device: default  max audio channels: stereo (must set stereo of 6/2/2009 passthrough work)  upmix: passive  enable ac3 spdif passthrough checked  enable dts spdif passthrough checked  aggressive sound card buffering off  use internal volume controls off

...but have tried many other configurations / combinations. seems 4 possibilities asound.conf file, 8 or possible combinations mythtv settings, can't possibly try every one!



aplay -l gives:
code:
**** list of playback hardware devices ****  card 0: nvidia [hda nvidia], device 0: alc883 analog [alc883 analog]    subdevices: 0/1    subdevice #0: subdevice #0  card 0: nvidia [hda nvidia], device 1: alc883 digital [alc883 digital]    subdevices: 1/1    subdevice #0: subdevice #0  card 0: nvidia [hda nvidia], device 3: nvidia hdmi [nvidia hdmi]    subdevices: 1/1    subdevice #0: subdevice #0


suggestions on how proceed great.

ATmega2560-Arduino Pin Mapping

hi community, in last days working on project using arduino mega 2560. on planning pin using found bugs in atmega2560-arduino pin mapping . if right there labels (such pwm) in 'mapped pin name' @ wrong row ( mixed pin numbers right one...) in attachment openoffice calc , pdf file corrected table. ( hope ;-) ) i post here tab separated table : code: [select] arduino mega 2560 pin mapping table atmega 2560 pin out arduino mega function nr name function function function mapped pin name function function datasheet 1 pg5 oc0b digital pin 04 pwm 2 pe0 rxd0 pcint8 digital pin 00 rx0 (usart0 receive pin, programming data input or pin change interrupt 8) 3 pe1 txd0 digital pin 01 tx0 (usart0 transmit pin or programming data output) 4 pe2 xck0 ain0 (usart0 external clock  input/output) 5 pe3 oc3a ain1 digital pin 05 pwm 6 pe4 ...

Crossfader Arduino Tutorial

hello i'm super newb please don't bash me much. i'm using led's , i've connected them correctly (finally) , wondering why program here ( http://www.arduino.cc/en/tutorial/colorcrossfader ) doesn't work? say's haven't declared crossfade. read directions on top , said crossfade needs used list order of colors. isn't declared in main part (void loop() )? or need declared before? nevermind void on bottom , needed before voidloop. lol anyways playing rgb led's wondering if has specific way of making them fade in , out different colors? (brightness , color mixing) code: [select] /* * code cross-fading 3 leds, red, green , blue (rgb) * create fades, need 2 things: *  1. describe colors want displayed *  2. list order want them fade in * * describing color: * color array of 3 percentages, 0-100, *  controlling red, green , blue leds * * red red led @ full, blue , green off *   int red = { 100, 0, 0 } * dim white 3 l...
