当使用“和谐V2.04”时，当运行“UnvialSalAdioOx解码器”演示应用程序时，我不能从PIC32蓝牙音频开发板（DMS3200）获得任何耳机音频输出。演示GUI显示音频文件正在播放，但是没有声音。演示，但是很好地播放音频文件正确，如果我使用和谐V1.11音频文件保存在USB闪存存储为wav立体声44.1kHz 32位浮动，我已经尝试了其他WAV采样率也没有运气。该D3332是一个原始的董事会，而不是新版本的红色按钮。任何想法，为什么音频播放是失败的和谐2.04和D3332将不胜感激。谢谢。
以上来自于百度翻译 以下为原文 I cannot get any headphone audio output from the PIC32 Bluetooth Audio Development Board (DM320032) when running the "universal_audio_decoders" demo app when using HARMony v2.04. The demo GUI displays that the audio files are being played, but there is no sound. The demo however works fine playing the audio files correctly if I use Harmony v1.11. The audio files saved on the USB flash are stored as WAV Stereo 44.1kHz 32bit float, I have tried other WAV sample rates also without luck. The DM320032 is an original board, not the new version with the red buttons. Any ideas as to why the audio playback is failing with Harmony 2.04 and DM320032 would be much appreciated. Thanks.

首先，UAD不支持32位音频流（既不是V1.XX也不是V2.04）。你能再检查一下你的WAV音频数据深度吗？请注意，如果使用AddioDead打开一个16位的WAV文件，AddioRead显示它是32位浮点数据，但实际上，它是16-BITH。第二，我下载并安装了V2.04和声，编程“红色按钮”版本的蓝牙音频DEV板，我有两个WAV文件玩得很好。这两个都是16位立体声音频文件，一个是16kHz，一个是48千赫。我在网上找到了这个免费的WAV测试文件，我可以在我的板上正确播放，HTTP://FielwaveSAMS.COM/KurZWiIL-K2000双BASS C1，请试试这个，看看它是否在你的板上播放。
以上来自于百度翻译 以下为原文 First off, UAD doesn't support 32bit audio streaming (neither v1.xx nor v2.04). Could you recheck your wav audio data depth? Be aware that if you open a 16-bit wav file using Audacity, Audacity shows it's 32-bit float data, but in fact, it's 16-bit. Second, I downloaded and installed v2.04 harmony, programmed "red button" version bluetooth audio dev board, I have two of my wav files playing just fine. both of them are 16-bit stereo audio file, one is 16Khz, one is 48Khz. I found this free wav test file online, which I can play correctly on my board, http://freewavesamples.com/kurzweil-k2000-dual-bass-c1 please try this one see if it is playing on your board. |

感谢JCUI在你的板上回复和运行演示。你是正确的，Advices将WAV文件作为32位浮点来报告，不管它是什么-多么令人讨厌。所以我使用VLC媒体播放器进行检查，并将WAV文件报告为16位。我也尝试了免费测试文件的链接，它也没有播放。正如我所提到的，文件在正确的V1.11下播放，所以我不怀疑WAV文件。有趣的是，你的新的“红色按钮”板在和谐V2.04下工作，因为我阅读修改需要得到“UnvialSaldioOx解码器”演示来与这个新的板一起工作。http://www.MICHCHIP.COM/FUMMS/M96098ASPXIT似乎已经将这些MODS应用于V2.04，以防止旧的M332432板（我有）工作正常。我将尝试和谐V2.03B。
以上来自于百度翻译 以下为原文 Thanks jcui for replying and running the demo on your board. You're right Audacity reports the WAV files as 32bit float irrespective of what it really is - how annoying. So I checked using VLC media player and it reports the WAV files as 16bit. I also tried the link to the free test file and it did not play either. As I mentioned the files are playing correctly under Harmony v1.11 , so I don't suspect the WAV files. It is interesting that your new "red button" board works under Harmony v2.04, as I read modifications are required to get the "universal_audio_decoders" demo to work with this new board. http://www.microchip.com/forums/m996098.aspx It seems these mods have been applied to v2.04, preventing the older DM3230032 board (which I have) from working correctly. I will try with Harmony v2.03b. |

“UnvialSalAdioOx解码器”演示与和谐V2.03B和原来的DMS3200板工作。我在V2.03B和V2.04之间做了不同的改动，Microchip似乎发生了很多变化。不幸的是，V2.04中的这些更改打破了原M3332板用户的音频回放。下面的代码恢复到DrvpPMPySt.c没有解决问题……有什么想法吗？
以上来自于百度翻译 以下为原文 The "universal_audio_decoders" demo works with Harmony v2.03b and the original DM320032 board. I did a diff between v2.03b and v2.04 and there seem to many changes made by Microchip. Unfortunately these changes in v2.04 break the audio playback for original DM320032 board users. The following code reversion to drv_pmp_static.c does NOT fix the problem... PLIB_PMP_WaitStatesStrobeSelect(PMP_ID_0, PMP_STROBE_WAIT_1); // PMP_STROBE_WAIT_2 in v2.04 PLIB_PMP_WaitStatesDataHoldSelect(PMP_ID_0, PMP_DATA_HOLD_3); // PMP_DATA_HOLD_2 in v2.04 Any ideas? |

新的版本（“红色按钮”）BT音频DEV板显示工作需要PMP的改变。所有新版本的BT音频DEV板都与V2.04和声一起工作，而不需要你入侵和声源代码。我用我的旧板测试过，它也与V2.04和声一起工作。所以我建议你做一个新的。安装V2.04和谐，程序通用音频演示框外，不做任何重新配置，看看这是否适用于你。
以上来自于百度翻译 以下为原文 the pmp changes are required to make the new version ("red button") bt audio dev board display work. All the new version of bt audio dev board works with v2.04 harmony without you hacking into harmony source code. I tested with my old board, it works with v2.04 harmony too. So I suggest you do a fresh install of v2.04 harmony, program universal audio demo out of box without doing any reconfigurations, see if this works for you. |

一个新的安装和构建的和谐V2.04 -仍然不与我的DM3200 32。但与和谐贝塔V2.03B一起工作。

这很奇怪，你的显示器效果好吗？当播放WAV时，两个音频DAC LED在播放吗？你能不能调试一下，看看有没有从I2S到DAC的数据？你能在另一个蓝牙音频开发板上测试吗？
以上来自于百度翻译 以下为原文 that's odd, does your display work good? Are the two Audio DAC LEDs on when playing wav? Could you debug to see if there has data from I2S to DAC? Could you test it on another bluetooth audio dev board? |

“红色”按钮（新）板和“黑色”按钮（旧）版本的D3332板应与MH V2.04。只有一个小区别是显示控制器。MH V2.04认识到这一事实，应该与任何董事会合作。
以上来自于百度翻译 以下为原文 Both the "red" button (new) board and "black" button (old) version of the DM320032 board should work with MH V2.04. There is only a minor difference is the display controller. MH V2.04 recognizes this fact and should work with either board. |

你好，只是想让你知道，靳是这个应用的开发者。她与图形化团队紧密合作，建立了驱动程序来对这个板进行修改。完全有可能我们错过了一些东西，因为我们无法对所有硬件进行物理测试。可能存在生产差异。我们最近的变化是专门处理这些变化，我们发现在我们的硬件生产。在2017年4月之前，该驱动程序被修改以处理两个较老版本，并从那时起建立新版本。在OTM显示控制器上有一个细微的差别，但希望对你来说是透明的。我的观点是，这是我们帮助你的过程（也希望是别人的）。因此，你能提供的信息越多，我们越有可能得到解决方案。不幸的是，我们没有得到你的结果与我们手边的董事会。我意识到这看起来像是一个缓慢的过程，但是如果我们不能重复你的结果，它会让我们猜测你的系统的差异。
以上来自于百度翻译 以下为原文 Hello, Just want to let you know, Jin is the developer of this application. She works closely with the graphics team that built the driver to make changes to this board. It is entirely possible that we missed something, as we cannot physically test all hardware. There may be production variations. Our recent changes are specifically to handle some of these variations that we found in our hardware production. The driver was modified to handle both the older versions out in the field prior to April 2017, and newer versions build since then. There is a subtle difference in the OTM display controller on the board, but hopefully that is transparent to you. My point is, this is our process of helping you (and hopefully others). So the more information you can supply the more likely it is we can get to a resolution. Unfortunately we do not get your results with the boards we have on hand. I realize this can look like a slow process, but if we cannot repeat your results, it leaves us guessing about differences in your system. |

我尝试再次加载和声，这一次显式卸载V2.04并删除其余文件夹，然后重新安装。在此之后，我很高兴地报告V2.04“UnvialSalAdioOx解码器”演示与我原来的D3332 -这是一个神话般的新闻！我有一个相当旧的DM3200（2014），注意到V2.03B和V2.04之间的许多框架变化，这最初使我相信旧的板不再支持100%。然而，在靳、C夹和迈克的原始的黑色按钮D3332与V2.04一起工作之后，我重新确认了我的和声安装。令人欣慰的是，和谐V2.04在各种版本的D3332上都得到了广泛的应用。谢谢你花时间帮助解决这个问题。
以上来自于百度翻译 以下为原文 I tried loading Harmony again, this time explicitly uninstalling v2.04 and deleting the remaining folders, prior to reinstalling. After which I am pleased to report that the v2.04 "universal_audio_decoders" demo is working with my original DM320032 - which is fabulous news! I have a fairly old DM320032 (Jan 2014) and noticed many framework changes between v2.03b and v2.04 which initially led me to believe that older boards were no longer 100% supported. However after helpful conclusive confirmation from Jin, Clip and Mike that the original black button DM320032 works with v2.04, I revisited my Harmony install. It is refreshing to learn that Harmony v2.04 works universally across the various releases of DM320032. Thanks for spending your time helping solve this. |

你好，很高兴听到它现在正在工作。顺便说一下，靳和“剪辑”都是为我们的32位师工作的工厂应用工程师，专门从事音频团队。随时可以使用公司支持系统提供支持票。但我们也定期监控并尝试对论坛做出回应。
以上来自于百度翻译 以下为原文 Hello, Glad to hear it is working now. By the way, Jin and 'clip' are both factory applications engineers working for our 32-bit division and specialize on the audio team. Always feel free to put in a support ticket using the corporate support system. But we do regularly monitor and try to respond to the forums as well. |
