No subwoofer output

SootierMovie249 · Jul 12, 2016

I can't seem to get my Xbox one to output to my sub. Here are the things I've tried so far:

1. Tried bitstream and 5.1 in display and sound, each followed by a system reboot.

2. Enabled surround sound in tv& one guide, followed by a system reboot.

3. Confirmed another device worked on the same receiver channel.

4. Swapped HDMI cables with the working device.

5. Set video output to HDMI instead of automatic in display and sound, followed by a system reboot

Any thoughts on what to try next would be greatly appreciated!!

:)

Certain Apps Don't Support .1 Audio Support (Subwoofer)

I recently purchased a Sony str-dn840 audio receiver along with front speakers and a subwoofer. The FR/FL speakers work fine with all applications, and I've had no problems whatsoever in that area.

The subwoofer is a BIC PL-200 powered subwoofer. It works fine for most uses thus far. I've tested it directly with the receiver via a bluetooth connection to my phone. I've also watched movies on xbox video and the xbox netflix app. In both cases, movies
played fine with subwoofer output.

However, when I use several other apps, the subwoofer has no output - this is without changing any settings on the receiver compared to other applications that I mentioned above which work fine. The xbox apps specifically that DO NOT work with the subwoofer
are as follows: youtube, vimeo, and the IE browser app (I tried pandora via the IE app). I have yet to try it with the HBO go app

I've searched google and these forums and found nothing related, so anything on this topic would be helpful at this point.

Audio output setting

LPCM means Linear Pulse Code Modulation and is effectively non-compressed digital sound. 48 in this case means a sampling frequency of 48 kHz, which is pretty much standard now (CD audio uses 44.1 kHz).

The Xbox 360 can only send out 2-channel LPCM for technical reasons. But other devices such as Blu-ray Disc players may be able to send multi-channel LPCM. So LPCM in itself does not imply any set number of channels. The number of channels received should be
indicated some other way by the receiver.

The Xbox 360 switches between Dolby Digital and LPCM based on content. Video content that has 2-channel sound is output in LPCM even if Dolby Digital is enabled. It shouldn't do this switching mid-game though.

LFE means Low Frequency Effects and is the dedicated low-bass reinforcement channel in multi-channel sound (the .1 in e.g. 5.1).

If there is no output from the subwoofer with Dolby Digital 5.1, you need to check the bass management in the receiver and set it up with respect to the performance of your speakers. Usually you'll set the size of the speakers (small or large), the bass output
(front, subwoofer, both) and the crossover frequency (in some receivers you're able to set this independently for the front, center and surround channels).

If a speaker is set to large, the bass will be retained in that channel. If it's set to small, the bass will be filtered out at the selected crossover frequency and sent out to the selected bass output, such as the main left and right speakers, the subwoofer,
or both in combination.

From your problem description it seems that the center speaker is set to small but the main left and right speakers are set to large. With 5.1 input this will put most of the bass in the main speakers except for the LFE. With 2-channel input and Dolby Pro Logic
II or similar enabled, much of the bass ends up in the center and is sent from there to the subwoofer.

Unless you have really beefy left and right speakers you may want to set them to small as well to send their low bass to the subwoofer (keep in mind that this means the subwoofer will work harder).

Hey Sottier!!

Could you explain a little better how you have the sub woofer connected to the Xbox as far as routing is concerned? Also is it a full surround sound system or just a sub and sound bar?

This link might help you out just a bit to kinda of guide you to make sure everything is hooked up in the correct order.

Hi Andrew. My name is Kyle and I'm an independent advisor.

If the soundbar works fine for apps on your TV but not your console, you may need to configure your TV's settings to enable Dolby Digital for HDMI devices. This should be in your TV's audio settings, listed as "Digital Audio Setting" or something similar.

You can also try setting up audio passthrough to see if that helps: https://support.xbox.com/help/hardware-network/display-sound/audio-passthrough

I've got a hdmi to vga component cable that's outputting my audio through a small 3.5mm port on the side (standard personal headphone jack) that's connected to my pc subwoofer which outputs to the rest of the speakers which works fine so i am sure you'll
be able to find one that has red/white on it or a converter for a single 3.5 to r/w.

I got mine off ebay, cheap, cheerful and delivered next day.

If the vibrations from the Subwoofer are that excessive, you might consider moving the subwoofer. Damage caused by excessive vibration while the system is running is not covered under the Xbox 360 warranty.
