Find out how far the problem reaches
- Begin with the speaker connections and receiver controls, then compare the available inputs.
- If only one source is quiet, check that device's connection and audio output. If all sources are affected, continue with speaker setup and sound modes.
A TV feed can be quiet while another connected device plays normally through the same system. We'd compare sources before trying replacement speakers, because a TV or set-top box can be responsible for low volume even when the A/V system sounds fine on its own.
These checks apply to speakers connected to a Sony A/V receiver. For a soundbar, use the separate soundbar troubleshooting referral in Sony Canada's receiver guidance (opens in a new tab). That keeps you on the instructions for the equipment you're actually listening through.
Make one change at a time and check for sound after each step, because each is a possible solution. Listen for sound returning or the low level improving before continuing. Once the symptom is resolved, you can stop working through the remaining checks.
Connections and playback controls come first
Check that the receiver and the devices feeding it are turned on. Verify that the speakers are properly connected, following the cables to their connections at both the receiver and the speakers. The physical connections belong in this check even when you've already been through the playback controls.
If your receiver has an A/B speaker selector, match its position to the speaker terminals you're using (opens in a new tab). Speakers connected to the rear A terminals require the selector to be set to A. That requirement still applies when you have only one pair of speakers connected.
Cancel MUTE, try increasing the receiver's volume and disconnect any headphones plugged into the receiver. Where your receiver uses the labels MASTER VOLUME and SPEAKERS, check that they aren't set to VOL MIN and SPK OFF respectively. These are the playback controls to check on receivers with those labels (opens in a new tab).
Does another input play normally?
Select the device you want to hear using your receiver's input control. Where provided, that means pressing the input button on the remote or turning INPUT SELECTOR on the receiver. Use your product's operating instructions for model-specific controls and connections; manuals are also available on your model's support page.
Work through the available input functions, including AM and FM where fitted. For a low-volume problem, compare the original source with another connected device, such as a CD player. You're looking for a useful distinction: whether every source is affected or whether the trouble stays with one.
If the problem occurs only with HDMI inputs, select the receiver's HDMI input and check that HDMI hasn't been assigned to another input name. Sony states that its Elevated Standard (ES) A/V receivers aren't designed to allow HDMI audio to be assigned to other input names. Follow that HDMI input-assignment limit (opens in a new tab) when checking an HDMI-only problem.
Follow the quiet source back to its output
For the affected source, check that its cable connection to the receiver is secure at both ends. Then try another input jack, using your receiver's connection instructions. This comparison checks whether the jack currently in use is involved in the problem.
When a television or set-top box sends audio to the receiver, its output settings may need attention. Depending on the source, you may need to disable its internal speakers or set the TV's audio output to FIXED or VARIABLE. These adjustments concern the source feeding your A/V system.
If you choose VARIABLE for the TV's audio output, increase the TV's own volume too. The TV level remains part of the check even after you've raised the receiver volume. Sony Canada's source-output guidance (opens in a new tab) allows either output setting, with that additional volume adjustment required for VARIABLE.
A speaker-setting mismatch can lower the volume
Check that the receiver's speaker setup matches the speakers connected. Some Sony receivers offer MicroSP, which causes low audio level when selected without Micro speakers attached. Use your model's operating instructions to find the speaker options and correct a speaker-type mismatch (opens in a new tab).
If your receiver has a test-tone function, run it using the instructions for your model and listen for sound. Keep the result available for any later support conversation, alongside which connected sources played normally and which remained quiet or silent.
Sound modes and output choices
Check whether the receiver is set to a surround sound mode, then try a different supported surround mode. Use the choices available on your receiver. This gives you another playback setting to check before moving on to replacement wires or speakers.
If your receiver offers TV+AMP and AMP, try changing TV+AMP to AMP. Keep the consequence in mind at this step: AMP won't output sound through the TV speaker. Judge the result through the speakers connected to the receiver.
The listening goal matters here. Sony's receiver guidance for these output choices (opens in a new tab) specifies TV+AMP when you want TV-speaker sound and suggests AMP when a multichannel audio source won't play. Choose using your model's controls and where you want to hear the sound.
Try replacement wires, then another speaker pair
If the settings and source checks haven't resolved the problem, try replacement speaker wires. Then try connecting a different pair of speakers, following your receiver's operating instructions for the connection. Both substitutions are included in Sony Canada's remaining speaker checks (opens in a new tab).
A change with replacement wires or speakers doesn't by itself establish which internal component needs repair. What you can report is concrete: whether different wires restored playback, whether another speaker pair changed the level, or whether the symptom remained throughout.
Who to contact when the problem remains
If all other input sources sound fine, or the A/V system sounds fine when playing separately, contact the manufacturer of the source that remains quiet. Tell them which device has low volume and which comparison sources play normally, so the request focuses on the affected source.
If the issue remains unresolved after the applicable checks, service may be required. Follow the Product Repair referral in Sony Canada's receiver support article (opens in a new tab). Describe whether all inputs are affected and give the results of the speaker-wire and speaker-pair comparisons.
