[dialer-app] During a live call, volume adjustment doesn't work in earpiece

[Christina Li]

Current situation:
Can't adjust the voice volume during a live call, making it difficult to hear the receiver

Desired:
Can adjust volume during a live call (Eg using the volume buttons on the device)

I marked ofono (Ubuntu) as "Invalid", as call-volume is something that needs to be handled by an external component.

Although the high-level ofono API provides a call-volume feature, RIL does not ( it only offers mute ), and thus call volume must be driven by the higher layers ( most likely telepathy-ofono ) either via PulseAudio, or the Android audio HAL interface.

I think there are two bugs here. The current code sets the voice volume to maximum.

I'm currently looking into how to change that volume from PulseAudio.

However, if your problem is that it's "difficult to hear the receiver", it sounds like the volume needs to be higher than it is today. Can you clarify this, and if so, which device is it that is having the problem (N4 or GN?), and does it occur both on earpiece, speakerphone and headphone modes?

[Christina Li (christina-li)]

I'm on Nexus 4.

Volume set today is too soft to hear. The same problem occurs for earpiece. Haven't tested with speaker phone yet.

[David Henningsson (diwic)]

That's a little weird - I have tested Nexus 4 today (with an image from a few days ago), and I think the call volume is quite ok.
(But it's difficult to verify when you're calling yourself for the testing.)

[Christina Li (christina-li)]

This was actually tested between two Nexus 4 between myself and another designer on the team. We tested it on 4 Sept's image.
We both had problems hearing each other.

Status changed to 'Confirmed' because the bug affects multiple users.

[David Henningsson (diwic)]

This should now be fixed on Mako (Nexus 4) - you can use the sound indicator to change the volume while you're on a call. Anybody wants to verify?

Still not working on Maguro (Galaxy Nexus), I don't know why. It looks like the relevant call to Android is working as expected.

@diwic
What's the plan to fix on Galaxy Nexus? Changing status back to confirmed until that is addressed.

[David Henningsson (diwic)]

@bfiller, something is wrong on the Android side, inside the proprietary blob somehow. rsalveti to investigate further.

[Christina Li (christina-li)]

@everyone- I tested the volume on Nexus 4 today. While on a call, the volume is now fine at maximum, however the same volume (maximum) is too soft when switched to speaker phone.

[Bill Filler (bfiller)]

just tested on Utopic build 157 and volume adjustment during call doesn't seem to control the volume of the earpiece, only the speaker phone. And turning the volume all the way down even when the speakerphone is on doesn't turn off all the sound as I expected, it just lowers it to a certain point.

This was fixed last week in image 203
