Understanding the Audio Landscape in 2024
Before diving into connection methods, let‘s examine why this matters in today‘s streaming environment.
Recent data shows streaming has officially surpassed cable TV viewership, with 34.8% of households now primarily using streaming services versus 34.4% for cable. Fire TV Stick, with over 50 million active users globally, represents a significant portion of this market. However, research from Consumer Reports indicates that 65% of streaming device users report dissatisfaction with their TV‘s built-in audio.
The soundbar market has responded accordingly, growing at 13% annually, with sales expected to reach $8.2 billion by 2026 according to Market Research Future. This growth reflects consumers‘ increasing recognition that quality audio is essential to the streaming experience.
Fire TV Stick Models and Their Audio Capabilities

| Fire TV Stick Lite | 1080p | Dolby Audio (pass-through) | 5.0 | HDMI 1.4 |
| Fire TV Stick (3rd Gen) | 1080p | Dolby Atmos (pass-through) | 5.0 | HDMI 1.4 |
| Fire TV Stick 4K | 4K | Dolby Atmos, Dolby Digital+, 7.1 surround | 5.0 | HDMI 2.0 |
| Fire TV Stick 4K Max | 4K | Dolby Atmos, Dolby Digital+, 7.1 surround | 5.0 + LE | HDMI 2.1 |
| Fire TV Cube (2nd Gen) | 4K | Dolby Atmos, Dolby Digital+, 7.1 surround | 5.0 + LE | HDMI 2.1 |
Understanding your specific Fire TV model is crucial when choosing the optimal connection method for your soundbar.
Why Connect Your Fire TV Stick to a Soundbar?
Modern TVs are remarkably thin, which is great for aesthetics but terrible for sound quality. There‘s simply not enough physical space inside a slim TV to produce full, rich audio. This is particularly noticeable when watching action movies, concert footage, or playing games where the audio experience is central to enjoyment.
The Audio Quality Gap
Technical measurements tell the story clearly:
- Average TV speakers frequency response: 300Hz-10kHz
- Average soundbar frequency response: 50Hz-20kHz
- Human hearing range: 20Hz-20kHz
This means TV speakers miss approximately 35% of the audible frequency spectrum that soundbars can reproduce, including much of the bass that gives sound its depth and impact.
Measurable Benefits of Soundbar Connection
A soundbar offers several advantages:
- Improved clarity – Dialogue becomes clearer and easier to understand
- Enhanced bass response – Feel the rumble of explosions or the depth of music
- Wider sound stage – Experience more immersive audio that seems to fill the room
- Dolby Atmos/DTS:X support – Many soundbars support 3D audio formats (compatibility varies)
- Simplified setup – Much easier to install than a multi-speaker surround system
Testing by audio engineers shows that even budget soundbars ($100-200 range) outperform the built-in speakers of premium TVs ($1,000+) in blind listening tests, with 92% of participants preferring the soundbar audio.
Understanding Connection Options: The Technical Breakdown
Before choosing a connection method, it helps to understand what you‘re working with. Fire TV Sticks themselves have limited connection options—they plug directly into an HDMI port on your TV or receiver. The connection to your soundbar, therefore, often happens either:
- Through your TV (Fire TV Stick → TV → Soundbar)
- Through direct connection using adapters or splitters
- Via wireless methods like Bluetooth
Your choice depends on the available ports on your devices and your priorities regarding audio quality, convenience, and budget.
Audio Format Compatibility by Connection Type
| Audio Format | HDMI ARC | HDMI eARC | Optical | Bluetooth | RCA |
|---|---|---|---|---|---|
| Stereo PCM | ✓ | ✓ | ✓ | ✓ | ✓ |
| Dolby Digital 5.1 | ✓ | ✓ | ✓ | ✗ | ✗ |
| DTS 5.1 | ✓ | ✓ | ✓ | ✗ | ✗ |
| Dolby Digital+ | ✗ | ✓ | ✗ | ✗ | ✗ |
| Dolby Atmos | ✗ | ✓ | ✗ | ✗ | ✗ |
| DTS:X | ✗ | ✓ | ✗ | ✗ | ✗ |
| 7.1 PCM | ✗ | ✓ | ✗ | ✗ | ✗ |
This compatibility chart clearly shows why HDMI eARC represents the gold standard for audio connections, especially if you want to experience the latest immersive audio formats.
Method 1: Connect via HDMI ARC/eARC (The Premium Option)
HDMI ARC (Audio Return Channel) and its newer version eARC (enhanced Audio Return Channel) represent the gold standard for connecting your Fire TV Stick to a soundbar. This method delivers the highest audio quality, including support for advanced formats like Dolby Atmos and DTS:X.
The Technical Edge of HDMI ARC/eARC
To understand why HDMI ARC/eARC is superior, let‘s examine the bandwidth specifications:
- Standard HDMI: Audio only travels from source to display
- HDMI ARC: 1 Mbps audio bandwidth (supports compressed 5.1)
- HDMI eARC: 37 Mbps audio bandwidth (supports uncompressed 7.1 and object-based audio)
This 37x increase in bandwidth with eARC is what enables the transmission of high-resolution, uncompressed audio formats.
What You‘ll Need:
- Fire TV Stick
- TV with HDMI ARC/eARC port
- Soundbar with HDMI ARC/eARC port
- High-quality HDMI cable (HDMI 2.1 recommended for eARC)
Step-by-Step Instructions:
Identify the HDMI ARC ports – Look for an HDMI port labeled "ARC" or "eARC" on both your TV and soundbar. On most TVs, only one HDMI port supports ARC functionality (usually HDMI 1 or 2).
Connect your Fire TV Stick – Plug your Fire TV Stick directly into an available HDMI port on your TV (not the ARC port, which we‘ll use for the soundbar).
Connect your soundbar – Using a high-quality HDMI cable, connect the HDMI OUT (or HDMI ARC) port on your soundbar to the HDMI ARC port on your TV.
Enable HDMI-CEC on your TV – This feature, sometimes branded as Anynet+ (Samsung), SimpLink (LG), or Bravia Sync (Sony), allows devices to control each other over HDMI. Navigate to your TV settings to enable this feature.
TV Brand CEC Menu Location CEC Brand Name Samsung General > External Device Manager Anynet+ LG General > SIMPLINK SIMPLINK Sony Settings > Watching TV > BRAVIA Sync Settings BRAVIA Sync TCL System > Control Other Devices (CEC) T-Link Vizio System > CEC CEC Configure your TV audio output – Go to your TV‘s audio settings and select "External Speakers" or "Audio System" as the output. Make sure ARC is enabled.
Set up your soundbar – Set your soundbar‘s input to "TV ARC" or "HDMI." Refer to your soundbar‘s manual for specific instructions.
Configure Fire TV audio settings – On your Fire TV, go to Settings > Display & Sounds > Audio > Dolby Digital Output and select "Dolby Digital Plus" or "Dolby Digital" depending on your soundbar‘s compatibility.
Brand-Specific HDMI ARC Setup Notes
For Samsung TVs and Soundbars
Samsung uses the term "Anynet+" for HDMI-CEC. On newer models, both features are turned on by default. If using a Samsung soundbar with Samsung TV, you may benefit from their proprietary "Samsung Q-Symphony" feature, which allows the TV speakers and soundbar to work together.
For Sony TVs and Soundbars
Sony uses "BRAVIA Sync" for HDMI-CEC control. When using Sony soundbars with Sony TVs, look for the "Sound mode sync" feature in the BRAVIA settings menu for optimized performance.
For LG TVs and Soundbars
LG uses "SIMPLINK" for their HDMI-CEC implementation. LG soundbars may offer an "LG Sound Sync" feature that enhances communication between LG TVs and soundbars.
HDMI Cable Quality Matters
Not all HDMI cables are created equal, especially for eARC connections. Here‘s what to look for:
- For HDMI ARC: High-speed HDMI cable (18 Gbps, HDMI 2.0)
- For HDMI eARC: Ultra High-Speed HDMI cable (48 Gbps, HDMI 2.1)
In testing, we‘ve found that low-quality cables are one of the most common causes of HDMI ARC/eARC failures and audio dropouts. Investing in a quality cable (typically $10-20) can prevent numerous headaches.
Advantages of HDMI ARC/eARC:
- Superior audio quality – Supports high-resolution audio formats
- Single remote control – HDMI-CEC allows you to control volume with your Fire TV remote
- Reduced cable clutter – Eliminates the need for separate audio cables
- Automatic device switching – Your system can automatically switch to the correct input
Compatibility Notes:
Regular HDMI ARC supports:
- Dolby Digital
- DTS
- 2-channel PCM
HDMI eARC (on newer devices) adds support for:
- Dolby Atmos
- DTS:X
- 7.1 PCM
- Higher bitrates overall
If you‘re using an older Fire TV Stick model (pre-2018) or older TV, you might be limited to standard HDMI ARC capabilities.
Method 2: Connect via Bluetooth (The Wireless Solution)
If HDMI ARC isn‘t an option or you prefer a wireless setup, Bluetooth provides a cable-free way to connect your Fire TV Stick audio to your soundbar.
Bluetooth Audio Quality: The Technical Reality
Bluetooth audio has improved significantly but still involves compression. Here‘s how different Bluetooth codecs compare:
| Codec | Max Bitrate | Latency (ms) | Quality Comparison |
|---|---|---|---|
| SBC (Default) | 328 kbps | 170-270 | MP3-like |
| AAC | 250 kbps | 160-220 | iTunes quality |
| aptX | 352 kbps | 70-100 | Near CD quality |
| aptX HD | 576 kbps | 70-100 | Better than CD |
| LDAC | 990 kbps | 160-220 | Hi-Res Audio |
Fire TV Stick primarily uses SBC and AAC codecs, which are adequate for most content but not audiophile quality.
What You‘ll Need:
- Fire TV Stick (all models support Bluetooth)
- Bluetooth-enabled soundbar
Step-by-Step Instructions:
Put your soundbar in pairing mode – The process varies by brand. Usually, you‘ll press and hold a Bluetooth or pairing button until an indicator light flashes. Consult your soundbar‘s manual for specific instructions.
Soundbar Brand Typical Pairing Procedure Sonos Press and hold the Connect button until the light flashes white Bose Press and hold the Bluetooth button until the light blinks blue Samsung Press and hold the Source button until "BT PAIRING" appears on display Sony Press and hold the Bluetooth button until "PAIRING" appears on display Vizio Press and hold the Bluetooth button until LED indicators flash Access Bluetooth settings on your Fire TV Stick – Navigate to Settings > Controllers & Bluetooth Devices > Other Bluetooth Devices.
