N8 / Belle / Car BT Audio - random problem with au...

Question

I updated my N8 to Belle when it was first released.  Ever since, I've been experiencing random problems with audio volume and how it is being output from the phone.
I have paired my N8 with my car (2012 Subaru Legacy) which allows me to make phone calls via the car and stream music to the car via BT from the N8.  Everything works fine most of the time, but there are some anomalies.
For example:  In the morning on way to work, I used Music Player to listen to songs in the car.  Later on during lunch break, I made two phone calls from the car.
After work, I turned on Music Player and started listening to songs, but realized that the audio is being played from N8's loudspeaker, and not the car speakers, even though the phone was paired with car BT.  
I restarted the application but nothing changed. I then turned-off BT on phone, turned it on again, and this time the audio was still output via the loudspeaker, but I could now see the song details on the car stereo display and skip to next song using car controls.
Another example:  I've also noticed that sometimes after using BT Audio in car, when I later play songs, the volume coming from N8's loudspeaker is maybe at 20% of what it should be and the volume buttons have to control over it.   It seems almost as if the phone still thinks it is connected to car and is letting the car stereo do the amplification. 
I tried different settings, but I can't pinpoint any specific cause of this behavior.
Has anyone experienced the same?  Solutions? 

Answer 1

For the song details to appear on the screen of car stereo you have to make sure your .MP3s have the ID3 info stored in them.  You can do that with programs like Winamp/MediaMonkey/others.  But I found that only works in my car when it wants to; it is never consistent, and most of the time it doesn't work.  I blame the phone software for that.
As far as sound quality with my BT Audio I couldn't ask for better.  It is very clear.  I have most of my MP3s encoded at 192Kbps; I found the lower rates not to be very clear.  I have not tested FM Transmitter in the Subaru (because BT works so good), but in my previous car it did not work well at all.  It would only work in one spot (under dash in the foot area) and even then it wasn't very clear.
