I guess this workflow is most appropriate for car/handheld devices but I use this headset on my PC where I'd prefer to have better quality voice audio (my VOIP client will allow me to pump audio through the speakers, and it is noticeably better sounding than headset). But such is life.
While using dconf. it temporarily removes but always reappear or reset and these media player sit just under sound menu. Ubuntu sound menu option looks like dogs tail. Never gonna be straight. I have tried several alternative method but all of them just temporary. VLC, Rhythmbox comes again under sound icon on Ubuntu 14.04

iPhone XR, ios 14 - The volume on my iPhone XR (normally set on maximum level) keeps lowering on its own all the way down to zero. Pressing the 'volume up' button on the side of the phone shows the volume at max, but when viewed in 'settings/sound and haptics' it shows all the way down. I can then raise it all the way up again in 'sound and haptics, but at some point it goes down to zero again (even though the side volume buttons show the volume at max. In 'settings/sound and haptics' I keep the 'change with buttons' function turned off. This happens on a daily basis. I discover the issue when I miss calls or texts.
the problem we're having is that it isn't configured properly for older devices, it views our car bluetooth as a pair of headphones, then listens to the sound coming out, and then adjust thinking the sound is WAY to loud, because obviously they're not actually headphones.
Also, have you checked to see if this might be explained by Attention Aware features? You can test turning that off under Settings > Face ID & Passcode: About Attention Aware features on your iPhone X or iPad Pro
it both instantly distracts you while driving and requires attention to rectify, cause the volume gets turned down so much so, that sound isn't audible at all. If you're running any form of navigation at the time it's really a big oof..
This has all been done you cannot it off . Apple said they were addressing this problem with the next software update 14.03 it is worse now and it definitely is not only air pods it is in car in home it is ridiculous you pay 800 for a phone and pay Apple Music and they turn sound down 4 times a today .
Yes yes yes have tried everything it is a glitch in apples software on the iPhones only as my iPad is the same as phone but I only have sounds and it never turns my music down come on s as pole address it
Ten clinically normal 6-month-old infants were presented with a series of sound stimuli while their behavior was simultaneously videotaperecorded and assessed live by 2 sound-masked observers. Two weeks later the same observers assessed the behavior from the videorecords. In both situations observers were permitted to see the babies for 13 sec at each trial. The first 5 sec formed a prestimulus observation period and the following 8 sec possibly contained a sound stimulus. Between trials the observers were allowed 20 sec in which to not (1) prestimulus activity, (2) confidence in response, and (3) facial, digit, and limb movements and "wholistic"impressions (e.g., "stilling"). The agreement between the live and video situations was modest for prestimulus activity and confidence in response, and fair to good for movement item. The outcome was rather similar to that of our earlier work on neonates and 6-week infants, although it did suggest a small loss of information with the videorecording of 6-month infants.
While sound moves at a much faster speed in the water than in air, the distance that sound waves travel is primarily dependent upon ocean temperature and pressure. While pressure continues to increase as ocean depth increases, the temperature of the ocean only decreases up to a certain point, after which it remains relatively stable. These factors have a curious effect on how (and how far) sound waves travel.
The area in the ocean where sound waves refract up and down is known as the "sound channel." The channeling of sound waves allows sound to travel thousands of miles without the signal losing considerable energy. In fact, hydrophones, or underwater microphones, if placed at the proper depth, can pick up whale songs and manmade noises from many kilometers away.
Hi All, I'm putting a decoder in my TT scale loco and was thinking about consisting it with a stationary sound decoder so I could add a sub woofer and speakers under the table. The loco is so small I don't want to add an onboard decoder right now but it seems like it should be pretty easy to rig up a spare soundtraxx under the table? Does anyone know how I should connect one? Would the decoder need some kind of load on the motor wires to work correctly? How should I connect the decoder sound output to a sub woofer/speaker setup? Any input would be greatly appreciated......DaveB
A small layout would be fine with one sound module and a set of speakers. It would have the advantage of giving you a strong base not found with onboard sound. With a large room filling layout, you might need multiple systems so that the sound can follow the train.
To answer some of the comments: Russ, My room is small so I'm hoping about 4 speakers spread around under the benchwork( plus one sub woofer) will let me hear the sound as if it is near the loco. I'd rather not wear headphones will operating so will try to adapt Lance's system to speakers. Looks like the audio amp was the part Rick was concerned about? Does anyone know if the decoder can sound right with nothing hooked to the motor leads, or does it need a load on there to make the sound match the speed and acceleration of the model? Now let's see how many were tying while I typed this :> ).......DaveB
I'm planning on building a "Lance style" sound "box" for my small 10ft x 12ft layout. Mine will be different in that it will contain a rotary switch (3 position) and three decoders (EDM 567, Alco 251, and GE 16 cylinder) so that I can use it for a larger number of my locos. I already have my wireless headphone, decoders, and the rest of Lance's suggested parts. I do need to get the rotary switch.
Why, btw? I am looking forward to using the BlueRail trains decoder via my cell phone and it doesn't come with onboard sound. Consisting a stationary sound decoder and transmitting via Bluetooth may be the ticket to making this work.
One of the links on the first page( thanks Rich) was to a youtube video of a sound system just like I want to make, all I need is to figure out where to get the small pre-amp that goes between the decoder and the sound system. If it sounds ok then I'd like to find a way to add freight car rumbling/wheel clacking, and flange squeal :> ) .....DaveB
The reason the audio transformer is in the circuit is to reduce the output voltage of the sound decoder. The decoder has a power amplifier that is meant to directly drive a speaker. That's too much for headphones and the like.
From your description, it sounds like you've found a 3.5mm "line level" IN> BT transmitter Out adaptor unit?
Any make/model details available? I've seen reference to some "no-namo"/"acme" branded units online but nothing resembling actual operational or audio specs.
Prof - you may be correct although I don't have a BR receiver to experiment with. I do wonder if anyone has experimented with using JMRI transmitting via Bluetooth? That might allow computer generated sound to remote speaker locations.
Another thought would be to simply use a sound decoder in line with a wireless receiver, such as Tam Valley, and then consist to the under table decoder which, if desired, could be broadcast via Blutooth to remote speakers.
I agree with Gino, if you are already of a mind to "go BlueRail", then simply pair to a decent BlueTooth speaker while also paired to the loco in question, and place the BT speaker where you need the sound to be.
Trying to kludge any form of BlueRail (motion/control) + DCC sound together at this time is Fool's Folly.
(Sounds great in theory, and a "merging of the best of both worlds",
which will only end in frustration, tears, and a loss of much hair for the foreseeable future...)
- Once you have control (and Power!) getting to the Stationary sound decoder, and an analog --> BT adaptor/transmitter kludged on the output,
you're looking to try and pair the one transmitter to _multiple_ discrete BT speakers. This is not easy, and many devices simply do not support such "One to many" BT pairing + Audio routing configurations.
(The cheaper and simpler the BT adaptor/device, the less functionality you can expect,
NOTE that the original "standard BT spec" is only capable of transmitting a single stereo-pair datastream of audio).
- ...and the result will be that as-many/all paired BT speakers will be attempting to force the same air-pressure audible "soundwave" signal into the room, with unknown/unpredictable/very-likely-annoying-as-all-getout acoustic results.
(No, running multiple stationary speakers will not create "doppler" effects in and of themselves,
and without extreme acoustic modelling of the room there is no way to predict any anomalies or phase-relationship collisions between the sources...)
To wrap:
- The "stationary sound" solution is certainly a way to get "bigger" sound from a typical DCC sound decoder.
- However, the sheer laws of physics governing the acoustic performance of stationary speakers, esp when fed by the sonically-limited source signal which is a typical DCC sound decoder, make it far more suitable for "single scene"/small-layout application than "room-filling" missions.
- No matter how many speakers you add, such a basic system is just that, basic. It has no knowledge of train position, listener position, speaker position, or the constantly-changing relationship between these elements, let alone the kind of audio matrixing/routing/Mixing/Panning required to emulate and track such relationships
- Using Headphones resolves a number of these issues, as the audio and listener positions are guaranteed "coincident". However, the "in-cab" perspective such a system provides may not match the Users/Modeller's desires/requirements.
