RE: AudioEngine testers - Linux only - Forsaken - 2012-07-19 I'm also having issues with DTS-HD and TrueHD pass-through with Intel built-in graphics on a i3 540 to a TX-NR709 receiver: DTS-HD: no sound TrueHD: noise xbmc seems to detect it correctly, I'm using latest xbmc from git.

Regular DTS/DD works fine through the amp, I don't have a TV though so I can't connect directly (only projector).

Why ? The driver supports it and it worked when I was testing with this patch: http://forum.xbmc.org/showthread.php?tid=96316 RE: AudioEngine testers - Linux only - furii - 2012-07-19 (2012-07-19, 21:00)Forsaken Wrote:(2012-07-19, 20:50)furii Wrote: dts-hd and truehd are only working with nvidia fermi cards under linux. if you want HD audio on intel or amd you'll need to switch to windows. search the thread and you'll see plenty of posts saying it doesn't work. don't ask me why, i'm not a developer. just relaying the current state of things. RE: AudioEngine testers - Linux only - bobb0 - 2012-07-22 Not sure if this is known (or if its only me) -- I searched trac and the forums and didn't find what I am looking for though I found an old (fixed) bug that was similar but not quite the same. Whenever (and only when) I experience a buffer underrun event (video pauses and dialog appears in upper right to indicate buffering progress), playback does not recover, becomes choppy (slo-mo) 3.x-4FPS with no audio. The log fills with the following message: Code: 10:37:00 T:2783955776 DEBUG: CDVDPlayerAudio:: Discontinuity - was:2765237553.364334, should be:2764052333.333333, error:-1185220.031000 Here is a pastebin of my full debug log: http://pastebin.com/x1Pb7X6g It doesn't matter if playback is using passthrough or pcm, streaming via SMB or from the internet (http/rtmp). Once the underrun occurs, playback does not recover.

Let me know :) RE: AudioEngine testers - Linux only - abudabi - 2012-07-22 Finally got around to hooking my machine up. Running Precise with Jul 13 build with latest nvidia driver from x-swat (302.17) into a yamaha RX-V767. I've chucked a whole bunch of files from demo-world.eu at it and everything bar one has worked flawlessly. DTS-HD MA : Check DTS-HD HR : Check TrueHD : Check Dolby Digital + : Not Check Don't think I've ever come across a media file that contains DD+ so I'm not too bothered. Let me know if I must include a debug log file. Keep up the great work guys! RE: AudioEngine testers - Linux only - abudabi - 2012-07-24 I see none of the audio devs (Daniela/DDDamien/Gniff) have logged in to the forums lately (1.5 to 2 months). Did someone else take over? Or are they still on the party yacht sipping margaritas after completing Eden RE: AudioEngine testers - Linux only - davilla - 2012-07-24 See android branch, the vampire AE gets a stake driven through it's heart and takes a dirt nap RE: AudioEngine testers - Linux only - abudabi - 2012-07-25 lol davilla I have a clip that AE cannot seem to lock onto the audio stream. The display of my AVR keeps on flashing. Video plays fine but no audio. If I look at the codec info using VLC in windows, it defines it as "A52 Audio (aka AC3) (a52)" If I let xbmc decode it, I can hear the audio just fine but passthru is not working. Let me know if you guys want more info / a debug log etc. RE: AudioEngine testers - Linux only - krip - 2012-07-27 Hi guys, Im having trouble playing some 2 channel, 44.1khz, 16bit flac files, while others work fine. On the troublesome files my receiver acts as if the audio signal is lost or changed every 2 - 10 seconds. My setup is debian squeeze with xbmc 12.0-ALPHA4 Git:20120724-8d978da. Hardware is intel core2duo, nvidia 210 gfx card. Audio out is onboard intel HDA connected through coax spdif to rotel rsp 1066 pre-amp. The files seems pretty similar: Code: xbmc@inez:~/tmp$ file fail/fail.flac okay/okay.flac aplay -l Code: xbmc@inez:~$ aplay -l aplay -L Code: xbmc@inez:~$ aplay -L I have audiophile and allow 44 transcode activated in advancedsettings.xml, but i tried disabling both options, it didnt fix the issue Code: <audio> Just for the record, the files i play are located on NFS, since my htpc has no local storage. It is pxe-booted and mounts root via nfs. I see the same issue when files are played through smb/cifs. Here is the debug log while playing the failing file: http://xbmclogs.com/show.php?id=5657 And here is the debug log while playing the okay file: http://xbmclogs.com/show.php?id=5658 I can play the failing file without problems using mplayer: Code: xbmc@inez:~/tmp/fail$ mplayer -ao alsa:device=default fail.flac It also plays fine directly out through the spdif: Code: xbmc@inez:~/tmp/fail$ mplayer -ao alsa:device=iec958 fail.flac If necessary I can provide a sample of the failing file .. and ofcause any other useful debug information that can help Thanks in advance. RE: AudioEngine testers - Linux only - direx - 2012-07-30 I have some additional Intel-related information for you guys: In theory, both Intel graphics cards (Sandy Bridge and newer) and the Intel Linux drivers are capable of supporting passthrough of HD audio (HBR). The Intel driver even reports the capabilities of a connected amp correctly, including Dolby TrueHD and DTS-HD. There is one issue though: it does not work. This is not XBMC's fault, it is due to a bug in the Intel driver. Status for Intel Sandy Bridge (and newer):
If you want to have this changed please complain to the Intel driver developers about broken HBR support through their mailing list. There also already is a bug report about this, so if you have any helpful information you may add it there. @wingrunr21: It would be nice if you could add some Intel-related information to the first post. - direx RE: AudioEngine testers - Linux only - solidsatras - 2012-07-30 @direx That was very interesting to read, thank you for the links. I´m eager to know when this will be solved.

What about the second big pull request for AE there has been no activity either.. :-( |
