问：
Anyone have issues playing 5.1 AC3 audio?
My setup is Pi to Samsung TV via HDMI and streaming media from NAS. Pass-through AC3/DTS are turned off and output 2.0 to all speakers is on.
When I play a file with 5.1 it freezes every 3-10 seconds for a second and then resumes.
It's not a network issue as I can stream other 720p and 1080p video without issues.
I assume it is struggling to decode the audio quick enough?
Is there anything else I can try besides remuxing all my files?
Also, what dirty region settings do people find best to use with Raspbmc?
任何人有5.1 AC3音频播放的问题？
我的设置是PI三星电视通过HDMI和NAS的流媒体。直通AC3/DTS关闭，所有扬声器输出2.0是对的。
当我玩5.1的文件，它冻结了第二次，然后恢复每3-10秒。
这不是网络的问题，我可以没有问题，其他的720p和1080p视频流。
我以为它正在努力解码音频的速度不够快？
还有什么我可以尝试除了remuxing我的所有文件？
此外，什么脏的区域设置人们找到最好与Raspbmc使用吗？
答：
The ARM is not really powerful enough to decode multichannel audio.
Using audio passthrough would fix your problem.
I generally find lower bitrate files (e.g. 720p web-dl) are normally okay with ARM decoding 5.1 channel audio, but 1080p is too much.
Overclocking will help (but not enough to play high bitrate 1080p with ARM decoding audio).
Hopefully there will be a codec pack available soon which allows the GPU to decode the audio, and that will be another solution.
ARM是不是真的足够强大的多声道音频解码。
使用音频直通，将解决您的问题。
总的来说，我发现较低的比特率的文件（例如720p的网页DL）通常与ARM解码5.1声道音频没关系，但1080实在是太多了。
超频将有助于（但没有足够的ARM解码音频播放高码率的1080p）。
但愿会有一个编解码器包即将上市，让GPU解码的音频，这将是另一种解决方案。 |
