Are you using external AVR?
See if you are using an external AVR. This may be one of the reasons for the‘no audio’ issue. Change it to your internal speakers and this may well fix itfor you.
Check bass speaker audio cable
Check if you have an audio cable from the TV which is connected to the bassspeaker that has buttons for different sources. If you don’t have, connect anoptical line from the TV to the speaker so that it can choose a differentsource for audio.
Try TV audio On and Off
Click Menu on your TV remote. In your audio settings, alternate betweensurround sound ‘on’ and ‘off.’ You may leave it on while you alternate them.Then go to Sound Leveling and turn it off. Your audio may just work fine.
Why HDMI Sound Does Not Work
There are several reasons why your HDMI sound might not be working. Theproblem could be anywhere from your PC, the HDMI cable, to your monitor or TV.Start by plugging your HDMI to another PC. If the issue persists, then thecable or your monitor/TV is likely to be the issue; if not, then the PC mightbe the issue. Also, try using another HDMI cable that is known to befunctioning. If the problem remains, then your PC or your monitor/TV might bethe issue. You can also use try using another TV/Monitor to narrow down theproblem further.HDMI cables can easily be replaced. However, if the PC is the issue, thenthere might be different reasons for the problem. It might be caused by anincompatible or wrong driver or even a selection of the wrong playback device.Your internal speakers’ soundcard might have been set as the default devicehence the PC is unable to switch from speakers to HDMI audio output. Youmonitor or TV might also not have been configured to receive the HDMI audio.This problem has also been seen in conflicting drivers where drivers thatdepend on each other had been disabled hence the sound card was not able tofunction properly. Below are the solutions to the problem. But before movingon, keep the cable plugged in and restart the devices. Also, make sure thecable is not faulty. Do not forget to check your Graphics Card e.g. NvidiaControl Panel for any wrong configuration. Do note that pre-GeForce 200 seriesNvidia cards don’t support HDMI audio. Realtek drivers are known to have thisissue.
Method 1: Enable and Make Your HDMI the Default Playback Device
Windows easily lets you switch from your speakers to your HDMI audio outputfrom the system tray. However, by making your speakers the default playbackover your HDMI output, the computer will not be able to switch to the HDMIoutput whenever it is plugged in. This is quite common whenever a PC has morethan one graphics or sound card. 1. Press Windows + R Key to open Run 2. Type mmsys.cpl and hit enter to open the sound and audio device settings window.Run mmsys.cpl command 3. Go to the playback tab. Now plug in your HDMI cable. It should appear on the list usually with the name of the monitor or TV. If not, right-click anywhere on the list and make sure that the “Show Disabled Devices” and the “Show Disconnected Devices” options are checked.Show Disabled Devices 4. If there is an HDMI audio device that is disabled, right-click on it and select “Enable”Enable HDMI Audio Device 5. Now click on your HDMI output device to select it. At the bottom click “Set as default” to bring it online whenever it is connected. Click OK to exit.Set HDMI Device as Default
Method 6: Change your monitor or TV audio settings
Besides changing the obvious things like setting your TV input source to thecorresponding HDMI input port and making sure that the cable is seatedcorrectly and firmly or that the TV is not on mute, you can also try tweakingthe TV/Monitor sound properties. 1. Go to your TV/Monitor menu > Settings > audio and try changing the audio coding to automatic or to HDMI. Make sure that your audio is automatic or HDMI audio is enabled.Change Audio Connector to HDMI 2. You can also try toggling the ‘Dolby Volume Mode’ to OFF and see if it helps (known issue in some TVs) 3. Try toggling the ‘Audio Range’ between WIDE and NARROW or any other setting you have (stereo, mono, standard, etc.).Change Audio Output to StereoThe HDMI graphics card may support HDMI Video, but may not support HDMI Audio;if your HDMI video card does not support audio, you may need to connectadditional audio cables between the PC and TV.
The Benefit of HDMI ARC
HDMI ARC transfers audio from a TV to a home theater receiver with the sameHDMI connection that transfers video from the home theater receiver to the TV.With HDMI ARC, you can hear TV audio through a home theater audio systeminstead of the TV’s speakers without also connecting analog or digital opticalaudio cables between the TV and home theater system.
How an Audio Return Channel Works
If you receive TV signals over an antenna, audio from those signals goesdirectly to your TV. To get the audio from those signals to a home theaterreceiver, connect an extra cable (either analog stereo, digital optical, ordigital coaxial) from the TV to the home theater receiver.However, with Audio Return Channel, the HDMI cable connected to the TV and thehome theater receiver can transfer audio in both directions. In addition,audio sources connected directly to the TV using internet, digital, analog,and, in some cases, HDMI inputs may also be accessed using the Audio ReturnChannel function.Specific HDMI ARC features are provided at the manufacturer’s discretion.Check the user manual for the specific HDMI ARC-enabled TV for details.HDMI.org
How to Activate Audio Return Channel
The TV and home theater receiver must be equipped with HDMI version 1.4 orlater to use Audio Return Channel. Also, the TV and home theater receivermanufacturer must have included it as an option within their implementation ofHDMI.To determine if a TV or home theater receiver has Audio Return Channel, see ifany HDMI inputs on the TV and the HDMI output of the home theater receiverhave an ARC label in addition to the input or output number. It will beassigned to one HDMI input on the TV and one HDMI output on a home theaterreceiver.To activate the Audio Return Channel, go into the TV’s audio or the hometheater receiver’s HDMI setup menu and choose the appropriate setting option.In some cases, Audio Return Channel is automatically enabled when HDMI-CEC isactivated on the home theater receiver.The appearance of the HDMI-ARC setup menu and activation steps in TVs or hometheater receivers may vary. The example shown above is for a Roku TV.
eARC (Enhanced Audio Return Channel) was developed and incorporated into HDMIversion 2.1 to overcome the limitations of ARC. eARC began to be implementedon TVs and home theater receivers in 2019.eARC adds the ability to transfer immersive audio formats, such as DolbyAtmos, DTS:X, and 5.1/7.1 channel uncompressed PCM audio from HDMI-connectedsource devices, as well as all audio from smart TV streaming apps. This meansthat on TVs with eARC, you can connect all audio and video sources to the TV.The audio from those sources can then be transferred from the TV to an eARCcompatible home theater receiver through a single HDMI cable connection.HDMI LicensingTV makers don’t always publicize which audio formats are supported on each TV.With both Audio Return Channel and Enhanced Audio Return Channel activation,steps may also vary. Check your user guide or contact tech support for theexact activation steps and features.TVs and home theater receivers that aren’t HDMI 2.1 compatible cannot beupgraded to accommodate eARC.
The power of HDMI ARC
ARC, along with help from CEC, can simplify your home theater system in twoimportant ways. The first and most useful feature HDMI ARC brings to casualusers is the ability to use one remote for all of your audio devices’ mostcommon functions. For this example, you may need to go into your TV’s settingsand activate CEC, usually found in the general settings. Depending on whatbrand of TV you own, the CEC menu option may instead go by its brand-centricsubtitle (Anynet+, Bravia Sync, etc.).Once everything is set up, your TV remote should power on a range of devicesfrom A/V receivers to soundbars like the Sennheiser Ambeo at the same time asyour TV and control volume as well. Simplicity is the name of the game here.In some cases, HDMI ARC also automatically sends your TV’s audio to your soundsystem without you having to deactivate your TV’s onboard speakers. In othercases, though, you’ll need to go into the settings in your TV’s menu toactivate “External Speakers” or “Receiver” to send sound out from the ARC portto your audio device. (More on that below.)The HDMI ARC port can also be handy for connecting outboard components likestreaming devices, making controlling them easier. Plugging a GoogleChromecast into your TV’s ARC port, for instance, may allow you toautomatically switch sources or even turn on your TV when you click the casticon on your phone or tablet. You may find similar results with othercomponents as well, including Blu-ray players and set-top boxes.Your exact level of functionality largely depends on each individual piece ofthis convenience puzzle. Not all TVs, disc players, media boxes, and audiosystems interact with each other in exactly the same way. As a general rule ofthumb, matching brands should give you the best overall experience, and thosegoing the heterogeneous route will want to search for any potentialcompatibility issues before making all the necessary purchases.
