通常，在手机上浏览内容比通过电视上的内置浏览器(built-in browser)更容易。Chromecast是一种流媒体设备，只需轻轻一点，就可以直接从手机投射到电视上，但它也存在潜在的音频问题。
例如，您可以将电视的音量设置在 15 左右——但这个音量级别太安静了，在投射时无法分辨出任何声音，因此您必须将其调高至 30。当您停止投射时，您几乎会用音量。本文将介绍如何解决这些Chromecast音频问题等。
修复 Chromecast 音频问题的 9 种方法(9 Ways to Fix Chromecast Audio Issues)
有很多潜在的Chromecast音频问题，从太安静的音量到根本没有音量。
检查连接(Check the Connection)
最简单的解决方法是检查Chromecast插入的HDMI端口。如果不是安全连接，您的音频可能会失真。将Chromecast牢固地推入端口并检查它是否摆动。
如果连接稳定，请尝试使用其他HDMI端口。在继续执行其他步骤之前，请先排除电视的硬件问题。例如，如果您只有一个HDMI端口，请插入另一台设备并测试其音频以排除Chromecast本身有问题。
重新启动您的媒体(Restart Your Media)
有时，您的音频问题是一个小故障。试试那句古老的格言：把它关掉再重新打开。关闭媒体播放器、Hulu、YouTube、Netflix，并停止投射。完全关闭后，继续投射。
这可以纠正许多最常见的问题。有时，像暂停和恢复这样简单的事情就可以解决它——但您可能需要重新启动演员表。
检查您设备的音频设置(Check Your Device’s Audio Settings)
如果您从手机或平板电脑投射，Chromecast可能会默认使用您设备的声音设置，而不是电视的声音设置。当您投射时，它会接管电视上的音量。尝试调整手机的音量，看看是否有影响。
有时手机的音量和电视的音量会脱节。甚至将音量更改一分都可以强制Chromecast同步并将音频级别更正到应有的水平。
连接到 5GHz 网络(Connect to the 5GHz Network)
如果您的 Wi-Fi 网络广播多个频段，请直接连接到 5GHz 频段而不是 2.4GHz 频段。这将提供最高带宽并帮助解决屏幕上的音频/视频同步问题。
更新您的浏览器(Update Your Browser)
如果您直接从Chrome投射，请确保您使用的是最新版本的浏览器。过时版本的Chrome cast 会导致流质量下降和音频问题。
选择 50Hz HDMI 模式(Select the 50Hz HDMI Mode)
根据您正在观看的内容，您可能需要启用 50Hz HDMI模式。某些特定内容（如体育广播）以该频率编码。
- 打开Google Home应用。
- 从设备列表中选择您的 Chromecast。
- 选择右上角的齿轮图标。
- 点击视频(Video)。
- 点击切换开关以启用 50Hz 模式。
这仅在您的电视允许此模式时才有效，但它可以轻松解决烦人的问题。
重新启动您的 Chromecast(Reboot Your Chromecast)
同样，答案可能在于“将其关闭并重新打开”。您可以直接从Google Home应用中执行此操作。
- 打开Google Home应用。
- 从设备列表中选择您的 Chromecast。
- 选择右上角的齿轮(gear) 图标。(icon)
- 选择右上角的三个点。
- 选择重新启动(Reboot)。
您的Chromecast(Chromecast)可能需要几分钟时间才能完全重启并重新连接到Wi-Fi，然后再进行投射。这通常会解决任何现有的声音问题。
延迟组连接(Delay Group Connection)
如果您通过一组扬声器播放声音，您的音频可能无法在每台设备上正确同步。Google Home应用具有可帮助您调整输出的内部设置 。
- 打开Google Home应用。
- 从设备列表中选择您的 Chromecast。
- 点击右上角的齿轮(gear) 图标(icon)。
- 选择音频(Audio)。
- 选择群(Group) 延迟(delay) 校正(correction)。
- 将滑块向左或向右移动，直到您的音频同步。
这不是一个自动化的过程，可能需要一些试验和错误。当您这样做时，最好在扬声器上播放歌曲作为音频的参考点。
恢复出厂设置 Chromecast(Factory Reset Chromecast)
如果一切都失败了，请将您的Chromecast 恢复(Chromecast)出厂设置。您可以通过Google Home应用中的设置菜单执行此操作。
- 打开Google Home应用。
- 从设备列表中选择您的 Chromecast。
- 选择齿轮(gear) 图标(icon)。
- 选择右上角的三个点。
- 点击恢复出厂(Factory) 设置(reset)。
- 点击重置(Reset)。
完成此操作后，您需要重新设置Chromecast - 但恢复出厂设置将解决许多问题。
Chromecast是一种将任何电视（只要它有HDMI端口）变成智能电视的简单方法。尽管您可能会在这里和那里遇到一些错误，但大多数都很容易修复 - 只需按照前面的步骤来解决您可能遇到的任何音频问题。
9 Ways to Troubleshoot Chromecast Audio Issues
Often, it’s eаsier to browse contеnt on your phone than through a built-in browser on a TV. Chromecast is a streaming device that makes it possible to cast directly from your phone to the TV with just a tap, but it comes with its share of potential audio issues.
For example, you might keep your TV’s volume set around 15 — but this volume level is too quiet to make out anything when casting, so you have to turn it up to 30. The moment you stop casting, you nearly blow out your speakers with the volume. This article will cover how to troubleshoot these Chromecast audio issues and more.
9 Ways to Fix Chromecast Audio Issues
There are a lot of potential Chromecast audio issues, from too-quiet volume to no volume at all.
Check the Connection
The simplest fix is to check the HDMI port your Chromecast is plugged into. If it’s not a secure connection, your audio might be distorted. Push the Chromecast firmly into the port and check that it doesn’t wiggle.
If the connection is steady, try a different HDMI port. Rule out hardware problems with your TV first before proceeding to other steps. For example, if you only have one HDMI port, plug another device in and test its audio to rule out a faulty Chromecast itself.
Restart Your Media
Sometimes the problem with your audio is a glitch. Try the age-old adage: turn it off and back on again. Close the media player, Hulu, YouTube, Netflix, and stop casting. After you have shut it down completely, resume casting.
This can correct many of the most common issues. Sometimes, something as simple as pausing and resuming can fix it — but you may need to restart the cast.
Check Your Device’s Audio Settings
If you’re casting from your phone or a tablet, Chromecast might default to your device’s sound settings rather than your TV’s. When you cast, it takes over the volume level on your television. Try adjusting the volume on your phone to see if it makes a difference.
There is sometimes a disconnect between the volume level on your phone and that of the TV. Changing the volume even by one point can force Chromecast to sync and correct the audio levels to what they should be.
Connect to the 5GHz Network
If your Wi-Fi network broadcasts multiple bands, connect directly to the 5GHz band rather than the 2.4GHz band. This will provide the highest bandwidth and help resolve audio/video sync issues on-screen.
Update Your Browser
If you’re casting directly from Chrome, make sure you are using the latest version of the browser. Out-of-date versions of Chrome cast result in lower-quality streams and audio problems.
Select the 50Hz HDMI Mode
Depending on the content you’re watching, you might need to enable the 50Hz HDMI mode. Some specific content (like sports broadcasts) is encoded at this frequency.
- Open the Google Home app.
- Select your Chromecast from the device list.
- Select the gear icon in the top-right corner.
- Tap Video.
- Tap the toggle to enable 50Hz mode.
This will only work if your TV allows this mode, but it can be an easy fix for an irritating problem.
Reboot Your Chromecast
Again, the answer might lie in “turn it off and back on.” You can do this straight from the Google Home app.
- Open the Google Home app.
- Select your Chromecast from the device list.
- Select the gear icon in the top-right corner.
- Select the three dots in the top-right corner.
- Select Reboot.
It can take several minutes for your Chromecast to completely reboot and reconnect to Wi-Fi, then cast to it. This will often resolve any existing sound issues.
Delay Group Connection
If you’re playing sound through a group of speakers, your audio might not be synced properly across each device. The Google Home app has internal settings that help you adjust the output.
- Open the Google Home app.
- Select your Chromecast from the device list.
- Tap the gear icon in the top-right corner.
- Select Audio.
- Select Group delay correction.
- Move the slider to the left or the right until your audio syncs.
This isn’t an automated process and can take some trial and error. It’s a good idea to play a song over the speakers while you do this as a reference point for the audio.
Factory Reset Chromecast
If all else fails, factory reset your Chromecast. You can do this through the settings menu within the Google Home app.
- Open the Google Home app.
- Select your Chromecast from the device list.
- Select the gear icon.
- Select the three dots in the top-right corner.
- Tap Factory reset.
- Tap Reset.
Once you do this, you’ll need to set up your Chromecast all over again – but the factory reset will fix many problems.
Chromecast is an easy way to turn any TV (as long as it has an HDMI port) into a smart TV. Although you might run into a few errors here and there, most are easy to fix – just follow the previous steps to straighten out any audio problems you might encounter.
