Error when changing volume

[alan_smithee]

I'm changing the volume with the dropdown-list and within scenes.
I've got a Pioneer VSX-921 and running Homeseer in Linux with Mono 5 (mono 3+4 also had this issue).

Hi, are you changing the volume using the HomeSeer volume device or using your remote control on your receiver? What type of receiver do you have?

[alan_smithee]

Hi Ultra, could you give response?

When I change the volume I get the following message.

Error	System.ArgumentException: Argument 'Expression' cannot be converted to type 'System.Int64'. at Microsoft.VisualBasic.Conversion.Val (System.Object Expression) [0x000b3] in :0 at HSPI_ULTRAPIONEERAVR3.hspi_pioneeravr.GetPioneerAVRVolumeLimt (System.String pavr_uuid, System.String vol_limit, System.Double vol_limit_default) [0x000ae] in <894c3e585f8143159c90dc33c5e4e986>:0

Error	System.ArgumentException

The volume does change but I get the error
