Hello, I have tried everything and as a last resort have decided to bug my fellow ALSA users via this mailing list in the hope that someone can help me with this problem. :) I am using ALSA on my MythTV (Knoppmyth) box. I have digital audio working ALMOST perfectly for everything except AC3 passthrough. DTS passthrough works fine and PCM works via SPDIF (however I am having some issues there which I will describe later) The computer is running an Asus M2NPV-VM with an onboard Nvidia MCP51 sound chip which uses Alsa's snd-hda-intel driver. When I attempt to play content (i.e. a DVD or a downloaded AC3 file) with AC3 passthrough turned on, it appears to work, there are no error messages in the logs of any of the programs I'm using (mplayer / xine / vlc / mythfrontend), and the light indicating Dolby Digital shows up on my audio receiver when I play AC3 content, but there is silence.. When I play DTS content the DTS light lights up, and it works perfectly in beautiful surround sound. The computer is running an Athlon64 4200+ chip and has 2GB ram. Here is the information collected from my system by ALSA: http://www.alsa-project.org/db/?f=018a14b26ebf14c181a9bd064c77c5d05bfaa92b The other problem I am having is with PCM audio. It seems that PCM audio only sounds "correct" on my digital receiver if I set up an .asoundrc file that forces the bit-rate to 44100Hz. 48000Hz results in the audio sounding slowed down and causes mythfrontend to generate Buffer Underrun errors when I test with it. Does anyone have the correct settings for this card? I know my receiver supports AC3 and DTS in 48000 so it should be able to take a PCM signal at that rate... :/ FYI the receiver on the other end is an LG HE903PAW. Does anyone have any tips? I have tried everything including replacing ALSA completely, and I feel like I am very close to getting this working 100%.
