Hi everyone,

Since iOS 15 (until iOS 17), it is not possible to increase or decrease volume from device while casting with Chromecast.

I opened a ticket to Bitmovin Support 19 months ago and that was the answer I got:

> We noticed that It’s a limitation in the Google cast SDK itself for iOS 15+ devices. Please see the below info from the Google cast website.

> **[GCKCastOptions Class  |  Google for Developers](https://developers.google.com/cast/docs/reference/ios/interface_g_c_k_cast_options#a74d509ff761dda7cf91e05e6e2c2e589)**

`- (BOOL) physicalVolumeButtonsWillControlDeviceVolume readwritenonatomicassign`  
A flag indicating whether the sender device’s physical volume buttons should control the session’s volume.

Is there a way to enable this flag from the Bitmovin Player iOS SDK? If not, is this feature planned in the roadmap?

Thank you in advance for your time,

EDIT: According to [this comment](https://issuetracker.google.com/issues/202423437#comment33) on IssueTracker, it should have been fixed on **iOS Sender 4.8.0**. This version has been included into Bitmovin Player iOS SDK [3.44.0](https://developer.bitmovin.com/playback/docs/release-notes-ios#3440) but it still doesn’t not work on the latest version (3.50.0)

We’re very interested in this functionality as well, seems like a small amount of work

There is currently no option to specify `physicalVolumeButtonsWillControlDeviceVolume`.

However, we **always** set `GCKCastOptions.physicalVolumeButtonsWillControlDeviceVolume` to `true`.

I quickly tested it with Google Cast SDK 4.8.0 and iOS Player SDK 3.50.0, and for me, this is working as expected (on iOS 17.2). I do see/hear a change in the receiver’s volume when using the volume buttons on the sender device.

Would it be possible for you to share any additional insights? Maybe a sample application?
