Some of you sound worse than those that are so called complaining. Ugh.
My issue is that on my second Focus (first stopped charging and replaced by ATT) will not play music (no sound) after I unplug from my car then plug in headphones after getting into the office. It's very frustrating to perform a reset everytime for this situation and if I want to reset everytime, I would go back to my Blackberry Tour.
When unplugging it from your car:
- Pause music
- Turn volume down to 0
- Unplug
- Turn volume up to 10+
- Resume music (see if it plays, if so continue below)
- Pause music
- Turn volume down to 5 (don't want tinnitus right?)
- Plug-in earphones
- Resume music (see if it plays)
If you hear absolutely nothing when playing through the built-in speaker after unplugging the device from your car, I would perform a full reset, then if still no good take the device back (the Focus seems to be plagued with issues).
If you can hear music after unplugging from the car, but still hear nothing through the earphones when plugging them in, take them out your ear and turn the volume all the way up as sometimes the volume can 'magically' be quieter per volume level (especially after playing games) so the device might be playing music, but it may be quieter than usual.
If you simply can hear nothing, I would attempt to fully reset your device and start from scratch, if the problem persists, I would return the device.
