What I have noticed since the updates is not poor reception but better reception for certain sites. I have 2 sites in a P25 trunked system that are not simulcast but depending on conditions would not usually come in to have traffic. They would occasionally get better at night or certain days. Or if I messed with the antenna. I had left them in since for the most part they were silent. I now see that they show up with traffic more often. Traffic when they come in is readable for the most part, I am guessing 90% of the time. The other 10% when traffic comes on those sites it may be 'garbled'. This has not happened often but something I did notice. If I skip to another site that is stronger and has that traffic it is fine. When you experience the garbled audio is it on a site you normally would not be hearing the audio on and were not getting before? Of course, this may have nothing to do with the updates and everything to do with conditions and propagation and is a coincidence.
