Has anyone else had this issue? No matter what I do I can't get the media volume to increase. With headphones or without. I've muted and unmuted the sound.
Help?
I have the same thing on my N4 and my N7 and I've tracked it down to happening when i power up the device while headphones are plugged in. I can plug in headphones and restart 10x's in a row and my volume is crossed out and won't go up. Unplug the headphones and restart while they are unplugged and it magically works again. I'd venture a guess this is what's going on. Since it occurs on my N7 and N4, which are made by different manufacturers but have the same (relatively) image, it's a software problem in AOSP. I haven't taken the time to see if it's reported through bug tracker because it's not a huge deal for me.
Wow! I thought you might be on to something, but I just tried this and did not get the same result. So, maybe there is still an app involved in some way?
Right now I'm just test driving my N4 for 30 days so I only have iheartradio, speedtest.net, and tapatalk installed. No other apps, other than the standard GAPPS. To limit it even further of those 3 i only have iheartradio and tapatalk on my N7. I'm guessing not everyone has those apps installed so it's possible theres an issue with an API that multiple apps are using which causes this issue to happen.
