This is probably not the time and place, but the things you describe happened to me when it comes to the new radio in the sim. Sometimes when people talk on any channel it sounds like it have higher priority than my engine. Never happened when my spotter talks, but I might have been lucky.
I heard people say the sound in iRacing is so good, compared to eg GT5, but I can't seem to hear that. I think it's way to loud and I don't mean I can't turn my volume down, but the sounds seem to be compressed so it will be audible on the worst of PC speakers. But it seems to be overdone. In most cases when I clip a curb the sound from the engine is already maxed out so the sound from the wheel hitting the curb is distorted and only produce a scraping sound in my speakers. And it doesn't help to turn the volume down, because it's not my amplifier or speakers that are maxed out.
To explain I will move over to the music industry, because it happening a lot here as well. And it's here it all started!
Here is a video explaining it
I noticed this when playing sounds from other programs on my computer when I drove. Like TeamSpeak. When pressing ALT+TAB to adjust the iRacing volume in sound mixer in Windows I ended up all the way down on 50% before it was at the same level as TeamSpeak witch tell me somebody played to hard with their sound compressor in iRacing. Also backed up with distorted sound in the sim.
And to information my hobby before iRacing was High End sound systems and I took that hobby further than most so I learned a lot. Any questions I' gladly respond.
So playing this loud Left888 will most likely kill your hearing or your speakers.
iRacing made it this way because they want it to audible on the the cheapest kind of speakers. I think their policy is to make the sim work on low end equipment, and I understand that. But buying high end equipment to try repair the sound is waste of money, because high end equipment only amplify the mistakes done to it.
It's like buying a 1 million dollar stereo and put Britney spears into the CD slot.. Not to talk bad about Britney, but you will get way better sound of it from your TV.. Because the high end system will only reveal the crappy production.
EDIT:
Doh forgot to say what I did to make it better.
Like I said I went into windows when the sim is running, ALT+TAB when in the sim. Turned the volume down to 50% in the sound mixer(optional), and I went into option to turn the sounds way down. Not sure the values, but it's about 50% of their adjusting band in option screen.
Then turn your volume up on your receiver instead if you feel the sound is too weak
Still sound's a bit digital in my opinion, but the sound clipping is down to a minimum
