TX-SR494 - Troubleshooting: Audio
Please use the following to troubleshoot and resolve audio issues with the TX-SR494 AV Receiver.
Before you start...
- Make sure that the speaker setup microphone is no longer connected.
- Confirm that the connection between the output jack on the connected device and the input jack on this unit is correct.
- Make sure that none of the connecting cables are bent, twisted, or damaged.
- If the MUTE indicator on the display blinks, press on the remote controller to cancel muting.
- While headphones are connected to the PHONES jack, no sound is output from the speakers.
- When "4. Source" - "Audio Select" - "PCM Fixed Mode" in the Setup menu is set to "On", no sound is played if signals other than PCM are input. Change the setting to Off.
No sound from the TV
Change the input selector on this unit to the position of the terminal to which the TV is connected.
If the TV does not support the ARC function, along with the connection by an HDMI cable, connect the TV with this unit using a digital optical cable.
No sound from a connected player
Change the input selector on this unit to the position of the terminal to which the player is connected.
Check the digital audio output setting on the connected device.
- On some game consoles, such as those supporting DVD, the default setting may be off.
- For some DVD-Video discs, you need to select an audio output format from a menu.
A speaker produces no sound
Make sure that the polarity (+/-) of the speaker cables is correct, and that no bare wires are in contact with the metal part of speaker terminals.
- Make sure that the speaker cables are not shorting out.
Check to see if the speaker connections have been made correctly. Settings for the speaker connection
environment need to be made in "Speaker Setup" in Initial Setup.
Depending on the input signal and listening mode, not much sound may be output from speakers.
- Select another listening mode to see if sound is output.
If surround back speakers are installed, be sure to install surround speakers as well.
A maximum of 5.1 ch playback is possible when Bi-Amping connection is used.
- Be sure to remove the jumper bar on the speakers when using Bi-Amping connection.
The subwoofer produces no sound
If the setting of the front speakers is "Full Band", the low range elements will be output from the front speakers instead of from the subwoofer during 2 ch audio input of TV or music. To output the sound from the subwoofer, make one of the following settings.
1. Change the setting for the front speakers to a setting of crossover frequency value other than "Full Band".
The range below the specified frequency will be output from the subwoofer instead of from the front speakers. If your front speakers have a high low-range reproduction capability, changing this setting is not recommended.
2. Change "Double Bass" to "On".
The low range elements of the front speakers will be output from both the front speakers and the subwoofer. Due to this, the bass sound may be emphasized too much. In such a case, do not change the setting, or make the setting with the above option 1.
- If the input signals do not contain subwoofer audio elements (LFE), the subwoofer may produce no sound.
Noise can be heard
Using cable ties to bundle audio pin cables, power cords, speaker cables, etc. may degrade the audio performance. Do not bundle the cords.
An audio cable may be picking up interference. Change the position of the cables.
The beginning of audio received by an HDMI IN cannot be heard
Since it takes longer to identify the format of an HDMI signal than it does for other digital audio signals, audio output may not start immediately.
Sound suddenly reduces
When using the unit for extended periods with the temperature inside the unit exceeding a certain temperature, the volume may be reduced automatically to protect the circuits.

sub still will not work
Greetings,
On my TxSR494 with 7.1 setup, I am unable to get sound from the Height speakers. Testing the speakers separately and they are in continuity and work. In setup Height speakers are not highlightable. I am not able to set 7.2 and am not using the outlet going to a second amp. Need health.
Thx
Terry Hatch
Hello Terry,
I'm sorry but I don't understand, if you are able to get sound or even test tones through the Height speakers then they should be highlighted since it was setup for the 7.1 speaker configuration. If you could please send us a photo of what you are showing in Speaker configuration and also the front panel of the receiver when you are not in the setup so we can we can see what could be preventing the height speakers from not showing. You can send this information at service@11tradingcompany.com for further troubleshooting.
Thank you
Jennifer
Hello
Can I use the TxSR without doing the initial setup?
Hello Rares,
You have to go through the initial setup to a point so that you can select the Never Show again option. Because if you terminate midway through the initial setup and turn off the receiver an back on it will come back. Here is the reference in the manual pg 85 https://assets.onkyo-av.com/product-manuals/TX-SR494_En_2022-11-02-192722_bapn.pdf.pdf?v=1734916776.
Thank you
