Sound problem with Z5

[khelben]

When I play a music either via headphone or via Bluethoot speakers I hear sound deformations / noise / Sizzles
Some time I also have the problem when I call.
I've restarted the phone and I still have the problem.

HI,

I've changer my Xperia Z5 with a new one, but I still have the problem.
The problem happens also in SAFE MODE.

I've 2 other phone at home (Nexus 5 and HTC One M8) and I don't have the problem with them so I'm sure that the problem is the Z5.
There is a problem with Z5 bluetooth.

I have the same problem with my z5 compact. A kind of crackling sound when using every kind of headphones. It is very noticeable especially at low volumes

I am not alone

Yes. I'm facing the same issue on the Z5 Dual I jst bought today.
I'm using my MDR-XB950BT Bluetooth Headphones and facing the same distortion issue.
I hope a software update will fix this.

You are not alone, I also encounter the same problem with my Xperia Z5 playing music through LG HBS 730 when the phone was on the initial firmware.

The update 32.0.A.6.152 appears to resolve this problem.

[khelben]

After last firmware is working better but is still not acceptable, i hope that Sony will fix this problem with a future firmware

[khelben]

After the update do you have reserted the phone? do you have created again the bluethoot connection?

I have the same exact problem. I use my phone to listen podcasts and talkshows so this has been bothering me very much. Especially in lower volumes you can hear that sizzling sound very clearly. Almost threw my phone because I was so annoyed of it. The problem is so bad for me that I'm thinking of returning this phone. Has sony addressed this problem and are they gonna do something about it?
