I have a rather old Motorola Droid Razr Maxx. A week or so ago it was having some serious problems which rendered it fairly useless, so I installed CyanogenMod on it.
Since then, sound will randomly completely stop from all sources. Various apps, music, even phone calls. Nada.
I'm fairly certain this is a software issue as the sound worked fine before flashing CyanogenMod and a reboot temporarily fixes the problem (and is so far the only solution I've found).
I'm fairly sure it doesn't have to do with the headphone state as neither speaker nor headphones works when the sound is broken, yet both work immediately after a reboot.
Constantly rebooting my phone so I can actually receive calls is rather sub-optimal. What can I do?
