Yes, HDMI carries both uncompressed video and digital audio signals in a single cable; versions 1.3 and later support up to 8 channels of 192 kHz, 24-bit uncompressed audio, and lossless formats such as Dolby TrueHD and DTS-HD Master Audio.
How do I get sound through HDMI?
Enable HDMI audio output in your display or soundbar settings menu; most devices auto-detect the link, but some require manual selection under an HDMI or Audio menu.
On a Samsung 2025–2026 TV, for example, head to Home → Settings → Sound → Expert Settings → HDMI Input Format (PCM) and switch it to “Auto” or “HDMI” instead of “Bitstream.” If you’re using a soundbar, double-check that the HDMI ARC/eARC port is picked in the TV’s audio output menu. After tweaking these settings, power-cycle both devices—turn them off, wait 30 seconds, then turn them back on—to make sure the new setup sticks.
Does HDMI always carry audio?
Yes, HDMI is designed to carry both video and audio; the interface transmits uncompressed video and compressed or uncompressed digital audio over a single cable.
Even the older HDMI 1.0 (2002) and 1.3 (2006) standards include audio support. Newer versions just add better quality—more channels, higher sample rates, and lossless formats like Dolby TrueHD. If you see video but no sound, the problem’s almost always in the audio settings on the source device or display, not the cable itself.
Why is audio not working through HDMI?
Audio fails when the wrong output device is selected, the HDMI cable lacks an audio return channel, or the device is disabled in Windows Sound Settings.
Start with the basics: is the HDMI cable plugged into an HDMI ARC/eARC port on both ends? (Cheap cables sometimes cut corners here.) Next, open Settings → System → Sound → Output (Windows 11) or Control Panel → Sound → Playback (Windows 10) and confirm “Digital Output (HDMI)” is the default device. If it’s listed as “Disconnected” or “Disabled,” right-click it and pick “Enable.” Then, head to the manufacturer’s site (Intel, NVIDIA, or AMD) and grab the latest GPU and audio drivers—outdated drivers break audio more often than you’d think. Finally, reboot; it’s the oldest trick in the book, but it works.
How do I get sound from computer to TV with HDMI?
Connect the computer’s HDMI output to the TV’s HDMI input and set the TV as the default audio device in Windows; no separate audio cable is required.
Here’s the catch: Windows sometimes stubbornly clings to the laptop speakers. If that happens, open Settings → System → Sound (Windows 11) or Control Panel → Sound → Playback (Windows 10), right-click “Digital Output (HDMI),” and choose “Set as Default Device.” Laptops with only one HDMI port? Grab a USB-C-to-HDMI adapter—but make sure it explicitly supports audio passthrough. No sense in adding another cable if it can’t handle sound.
Why is there no sound on my TV when connected to the laptop with HDMI Windows 11?
Windows 11 defaults to the laptop’s built-in speakers unless you manually switch the output device to HDMI; the issue is usually a simple selection error in Settings.
Right-click the speaker icon in the taskbar, pick “Sound settings,” and under “Output,” open the drop-down labeled “Choose where to play sound.” Select your TV from the list (it’ll usually show the model name). If HDMI isn’t an option, right-click the speaker icon again and choose “Open Sound settings.” Scroll down to “Advanced sound options,” then click “More sound settings.” In the “Playback” tab, look for “Digital Output (HDMI)” and set it as default. Still not working? The device might be greyed out. Update your Microsoft and Intel audio drivers, reboot, and try again.
How do I get my computer to play sound through my TV?
Connect the computer’s HDMI or DisplayPort output to the TV, then select the TV as the default playback device in Windows; a second audio cable is unnecessary.
USB-C users, listen up: not all adapters are created equal. You’ll need a certified USB-C-to-HDMI 2.1 cable that explicitly mentions audio passthrough. Plug it in, then open Settings → System → Sound → Output and pick your TV. Still hearing sound from the laptop? Right-click the speaker icon → “Open Sound settings” → “Troubleshoot.” Windows can usually sniff out the problem and fix it automatically—no PhD required.
How do I get sound on my TV from my computer Windows 10?
Set “Digital Output (HDMI)” as the default playback device in Control Panel → Sound → Playback; this routes audio to the TV over the same cable used for video.
Open up Control Panel → Hardware and Sound → Sound → Playback, right-click “Digital Output (HDMI),” and choose “Set as Default Device.” Hit “Apply” and “OK.” Still no sound? Check two things: first, make sure the cable is HDMI 1.4 or newer (older cables can be finicky). Second, verify the TV input is set to the correct HDMI port. If it’s on the wrong one, you’ll get video but no audio—classic.
Why is there no sound on my TV when connected to the laptop with HDMI Samsung?
Samsung TVs require HDMI-eARC or HDMI-CEC to be enabled and the correct input format set to PCM/HDMI; a disabled HDMI audio device or incorrect input selection is the most common cause.
First, grab your Samsung remote and press Home → Settings → Sound → Expert Settings → HDMI Input Format. Pick “PCM” or “HDMI” from the menu. Next, enable Settings → General → External Device Manager → Anynet+ (HDMI-CEC). Finally, on the laptop, open Settings → System → Sound → Output and select your Samsung TV. If it’s greyed out, right-click the speaker icon → “Open Sound settings” → “Manage sound devices” and enable the HDMI output. Still silent? Try swapping in a different HDMI cable—some budget cables skimp on the audio return channel wiring, and that’ll kill your sound faster than you can say “HDMI.”
Why is there no sound on my TV when connected to the laptop with HDMI Windows 11?
The same Windows 11 audio-selection issue repeats across different brands: choose the HDMI device in Settings → System → Sound → Output; a disabled or unselected device is almost always the cause.
Right-click the speaker icon in your taskbar, choose “Sound settings,” and under “Output,” pick the HDMI device. If it’s missing entirely, open Settings → System → Sound → More sound settings → Playback, right-click in the empty space, and check “Show Disabled Devices.” Enable the HDMI device if it appears. Still no luck? Update your drivers and reboot—this problem’s usually tied to outdated audio stacks.
Why is there no sound on my TV when connected to the laptop with HDMI Samsung?
On Samsung TVs, enable HDMI-CEC (“Anynet+”) and set the HDMI Input Format to “PCM” or “HDMI” in the TV’s settings menu; then confirm the HDMI device is enabled and selected in Windows.
Grab that Samsung remote and press Home → Settings → Sound → Expert Settings → HDMI Input Format → PCM. Next, enable Settings → General → External Device Manager → Anynet+ (HDMI-CEC). Now, on the laptop, open Settings → System → Sound → Output and select your Samsung TV. If Windows refuses to recognize it, go to “Manage sound devices” and enable the HDMI output. Still dead air? Swap in a proper HDMI cable—some cheap ones cut corners and omit the audio return channel. That’s the fastest way to kill your sound without realizing it.
