First up, many thanks for any help and for your time.
I am running CM 11 Nightlies (currently at 20140517) but this issue has been happening ever since I installed CM 11.
I use Apollo for music. The player will play fine for a period (sometimes more than an hour and sometimes just five minutes) and then suddenly the sound will disappear while the player keeps playing. I then have to reboot the phone for the sound to come back as manually shutting the app down does not work.
I don't believe it is an Apollo issue but think it is a sound issue as this happens with Google Music as well as Ginkgo Audio player as well (which I use for audiobooks).
I have already searched the net and the forums but haven't found anything yet.
Would be grateful for any advice.
