Call Volume - again

[dertimaushh]

Hi Ted,

I finally nailed down the issue with my call volume. Running the latest FW 1.1.17.

Calls came in very quiet - even when previous Bluetooth Audio was very loud and the phones volume was maxed out.

In order to raise the call volume I had to turn the volume knob at least 20 time before anything changed. It took 100 turns in order get the desired call volume which makes adhoc adjustments in a call almost impossible.

It feels like BlueBus has issues listening to the command inputs of the volume knob when in call mode.

Again for Audio all is fine.

Any ideas?!

Best regards, Tim

I have the same issue. Audio is good, but when a call comes in, I have to crank up the volume to hear anything. In my 2001 E46 330i Touring the call sound comes from the speaker below the steering column.

You have an E38, right? Does it have the DSP Amplifier or not?

When this issue crops up, are you in Bluetooth mode or AM/FM/CD/TAPE?

@blackfoton

I've never seen a car with the speaker on the bottom of the steering column but I know they're out there (I bought one such speaker to test during development). I'm guessing this is a Non-Nav car as well?

Hi Ted,

no DSP, in Bluetooth mode.

Hey Ted, yes Non-Nav car. I'll test it a bit further, if this only affects classic phone calls, or VIOP also (Facebook Messenger etc) and report back.

@dertimaushh,

Any change I can get a log of you making a call and changing the volume? There's no reason that audio should only increment slowly in Bluetooth mode. https://github.com/tedsalmon/BlueBus/wiki/Gathering-a-Log

@blackfoton

Weird. You should NOT be getting audio from that speaker when you take calls in Bluetooth mode -- they should play over all speakers. Outside of Bluetooth mode, the system will likely use the single speaker.

Thanks! -Teed

Will give it a try.

It doesn't matter what mode i am initially in when I make or get a call.

The volume behaviour is always the same - as described above.

Btw is there a way to route calls via all speakers?

BR, Tim

@dertimaushh,

It should always route through all speakers if you're in Bluetooth mode, that's why I am a bit confused and want a log :)

Issue Update after a quite evening in my car.

Calls get routed via all Speakers in Bluetooth Mode and via a single Speaker outside of Bluetooth mode. Never realized before.

In calls outside Bluetooth mode all is good - I can increase and decrease the call volume ad hoc and all works fine.

The issue is only present in Bluetooth mode - which I am using like 99% of time.

Still need to capture a log for that.

Best regards, Tim

@dertimaushh,

Did you happen to retrofit a Siemens CID radio from the E8x into your car? Those radios don't respond to volume changes while in TCU mode -- a bug I'm working on separately :)

Thanks! -Ted

[dertimaushh]

No, using a normal BM54 with flat pins.

Hi Ted!

Yes, it's a non-nav car.

Tested it today:

• calls are always routed to all speakers (I was wrong before: the speaker below the steering column doesn't do anything now)
• no matter how the call is made –incoming or outgoing, phone call or VOIP( tested Facebook Messenger)–, the call volume (set to max on phone) is always way lower than the music volume
• my voice volume was fine on the other side

Hi Ted,

Wanted to log my problem - and for some reason decided to re-flash the latest firmware.

And now everything is working fine - lol. 😅

Will drive my car down to the Cote D'Azur next month - so plenty of testing time.

Best regards, Tim

@dertimaushh Hey Tim,

Great to hear! Please let me know if the issue reoccurs.

Thanks! -Ted
