I connected the Oticon TV adapter 3.0 to the optical output of the TV. So I expected that the TV volume would not play any role.
But it does!
On the TV (Sony XH 90) I can’t do anything in the settings to change this. So if the rest of the house listens more quietly through the speakers, it’s quiet on my too.
In that case, you probably need to setup the TV to output to Speakers + Optical, so that you can manage volume separately… can’t imagine a Sony TV not having that option
It seems I found the reason why changing the volume on the source affects the volume on the .
I watch TV channels via a cable Move STB device that is connected to the TV with an HDMI cable and to the wi-fi router with an ethernet cable.
For some reason, changing the volume on either the TV or STB remote causes a simultaneous change on both devices (STB and TV).
I assume that the same volume control signal is on both remotes.
Everything is fine with the TV. Changing its volume has no effect on the HA, but there are changes on this STB, which is usually manipulated, while the TV remote is used to turn it on and select the input.
Previously, when this TV had DVB-C (not Move), each remote only affected its own device. It is the same now on the other TV.
The volume result is the product: Set volume on STB x Set volume on TV
So if, for example, the STB is set to 0.5 (50%), and the TV is set to 0.4 (40%), the TV speakers will output 0.5x0.4=0.2, i.e. 20% of the maximum volume.
And in my case, also on the TV adapter.
The maximum sound from the TV adapter goes to the TV. But if the STB is set to 0.5, then the input signal to the TV is halved, so the total maximum is 0.5x1=0.5. If the STB is set to 0, regardless of the TV being set to 1 (100%), the result will be 0!
For this reason, when someone in the house changes the volume with the STB remote, the total sound to the TV adapter, i.e. my hearing aid, also changes.
If the change on the STB had an effect only on the volume from the speakers, and the TV adapter always had the maximum signal from the TV, then I would not depend on whether someone changes the volume on the STB.
As a retired graduate electrical engineer (electronics and telecommunications) with experience in the development and production of audio equipment and a professor of audio electronics, I claim:
STB and TV are in a chain.
STB does not have an audio amplifier, TV does, and its gain (A) is fixed.
The output level on the TV speaker depends on the input level, i.e. approximately, Uout = A x Uin. (I would not mention automatic gain control now)
TV’s Uin is the output signal from the STB.
Both devices have a control that can be used to attenuate the signal, and as in the cascade, the attenuation is the product of the attenuation of both regulators.
The digital (optical) audio output of the TV is maximum (or can be adjusted accordingly, depending on the TV) and does not depend on the TV regulator.
But, if, for example, with the STB you change the input signal level to the TV, this maximum signal at the digital output will also change.
Therefore, if the STB’s audio signal is completely muted (Uin=0), zero times any TV gain is zero! No sound on the speaker!
The same applies to the speaker and if the TV’s sound is muted.
I believe my colleague agrees with this.
The problem I have with the TV adapter is that I don’t have a signal on the optical output that is independent of the settings on the STB!
When someone changes the volume using the STB remote control, the volume in the hearing aid also changes.
When watching TV without the STB, changing the volume on the TV does not affect the volume in the .
I’ve already explained that.
But, here it is again.
The TV adapter is connected to the digital optical output of the TV.
The volume can be changed on both the TV remote and the STB (mostly the household members use it).
Since I installed a new STB with the Move application, the volume controls work like this:
Changing the volume with the TV remote only affects the TV controller. That’s how it should be.
In this case, there is no change on the . That’s how it should be.
However,
Changing the volume with the STB remote affects both controllers, so both are turned up/down.
In this case, the volume is changed in the HA. That’s not right!
Previously, with the classic DBV-C STB (without the Move app), as well as now on my other TVs, the volume is changed only on the device for which I use the remote.
It’s something about how this STB pairs with controlling this TV’s volume. Possibly you can unpair and then re-pair and get a different result or you might find it does the same thing. Have you tried technical support for the STB or to see if they have another model which might work better for you with this TV.
@Speedskater
I’m sorry to say that you don’t think correctly.
As I said, with my TV remote, I change the volume on it. But on the TV adapter it doesn’t change like that, it’s always at maximum!
But with the STB remote, the volume of both the STB and the TV is changed at the same time, i.e. the change is double. This also affects the volume of the TV adapter, i.e. on the .
Yes, you missed that I said the TV adapter is connected with an optical cable.
And it is a fixed volume if manipulated with the TV remote.
But, with the STB remote, you get gain/attenuation and even mute if you set it to zero.
That’s what I have.
Is there something wrong with the STB, I don’t know.
A little over a year later, I came across this thread as I was doing research on the TV Adapter (I just got new Oticons this week; I’m a life long hearing aid user since the age of 2). I kind of got lost in all the acronyms etc (STB???). My new aids has Bluetooth but my Roku TCL TV doesn’t as far as I can tell- thus the research on the TV Adapter. My question is how can I have the TV on mute but sound going to hearing aids. My current set up is a DAI cord from TV headphones jack to my hearing aids. I prefer not to have the TV sound blaring and disturb my family members lol.
I also discovered that my android phone is probably too old to reliably connect to my via Bluetooth (Samsung Galaxy A14)- mainly because Oticon leans heavily to Apple products ). My HP laptop/Windows 11 is the same way… doesn’t have LE audio. It connects for about a second then disconnects. I did see the ConnectClip for that solution but the thing is a bit big/long and would not fit well on my laptop (unless I get a USB hub- which I’ve been meaning to do anyway once I find spare money…if ever).
So might be looking into iPhone- I’m basically an android/Windows duck even though I have a macbook pro (required for the coding bootcamp) and an iPod decades ago.
Why not just get the Oticon TV streamer? Or … if your TV is new enough, you may be able to stream via (not sure which variation) from the TV to your aids. Otherwise, you can stream from, say, a Roku Stick 4K or later from the Stick to your with volume from the TV muted. That would be a lot cheaper than the Oticon TV streamer.
If you search the web on ‘oticon compatibility’ (no quotes), you’ll be able to check your phone. With Intents, you need an accessory to stream music or use the phone hands-free.
Yes I’m looking at the Oticon TV Adapter- holding off a bit as I’m in trial mode right now (potential to try Phonak if I want).
Hmm I have a ROKU TCL TV and a ROKU 4K Stick both of which we got last year (we ordered 2 but for some reason they sent us 3- Roku told us to keep it- free). I will look into how I can get it to stream from the 4K stick. Didn’t see any options related to Bluetooth on the Roku Settings- yet.
For the PC - will get the Easy LE Adapter. Surprised that the HP laptop does not have (Nothing in Windows 11 settings either).
I’ve looked at the Oticon list for phones and concluded that Galaxy A14 is a no-go as that phone only went up to Android 15.
The LE Adapter only work with Oticon Intent and Zeal. For PC you need the connect clip or if you plan on gaming on the PC, use the TV adapter for low latency
