Audio has started to causes buffering of video playback
#1
I have a dedicated windows HTPC running xbmc. It has served me faithfully for a couple of years.
Details about my setup:
XBMC 13.2
Windows 7 SP1 64-bit
CPU: Intel® Core™ i3-2120T CPU @ 2.60GHz
GPU: AMD HD4650
8 GB RAM
SSD local OS drive
Media streamed from server via SMB shares connected with Gigabit network.
Connected with HDMI to my Panasonic 42" plasma
Desktop Resolution: 1920x1080 32Bit at 50Hz

Suddenly, at about two weeks ago using XBMC became unberable. I have constant bufferings pausing playback.

I have verified that my shares are not the problem, it's a dedicated zfs server with a lot of processing and performance headroom, just for fun i verified that i could at least start 6 separate streams of raw Blu-ray rips using VLC from this server without any issues så streaming a compressed episode of "Louie" should compare to idle.

From my non-expert view of logfiles it seems to me like it is somehow audio troubles causing buffering.
I have a fairly simple setup, hdmi connected to my Panasonic plasma, audio is two channel analog going from my plasma to a simple a two channel amplifier.

After searching for a loong time after other problems i found a hint that audio might be the reason for my trouble.
A wiki here at KODI states that AMD users should use WASAPI and AMD HDMI as output and not WASAPI and Realtek HDMI like I was currently using. (A bit unsure about why this had worked before, or if it hade magically changed).

Anyhow, it seemed to work, I could watch an entire episode of homeland, skip back and forth, everything was smoothe again Smile

But, the day after, same settings, buffering was back again Sad Tried every other audio output, but to no avail.
Finally I even plug a mini jack right into my pc, configured it correctly in windows, selected this as my output in xbmc, and still, no dice !!! XBMC was still buffering.

Any thoughts or insights is highly appreciated. I am seriously considering both upgrading the OS on my box to win 8.1(was planning to wait for 10), updating from XBMC 13.2 to Kodi RC but since I have a centralized library with mySQL I am a bit hesitant about the "one way upgrade".

The log say's you're using the analog DIRECTSOUND: Speakers (Realtek High Definition Audio), so please explain exactly how everything is connected together and how you want the audio routed, also post a screenshot of all your audio settings.

Sorry about that, the attached log file belonged to my last attempt to use a mini jack and connect connected from pc and directly to amplifier using analoge REALTEK speaker output. Note, vlc worked fine also with this version.

Anyhow, here is some screenshots and a logfile from my normal setup. The logfile shows startup and playback off an episode of Treme until it starts buffering. Note, I have cut away some parts of the logfile to reduce size, but the parts I cut away was mostly related to movie scraping, scanning etc.

Brief description of my setup:

PC->AMD 6450HD gpu->HDMI->Panasonic Plasma display(some years old)-> stereo analog output from TV->Creek 2 channel amplifier

Hope this is enough to dig deeper into this issues.

Info about drivers. Before my buffering problems began I had simply used drivers from windows update. As part of the debugging/troubleshooting process I have installed the latest AMD drivers "amd-catalyst-14-9-win7-win8.1-64bit-dd-ccc-whql". Did not make any difference.

Should I consider locating and downloading the latest realtek audio drivers as well, or are the drivers from windows sufficient?

Yeah, they do. I think you're trying to post a truncated URL.
