Hi,
I am experiencing the following issue on my Xperia V, both with 9.1.A.1.140 and 9.1.A.0.490.
When plugging in my headphones, the loud speaker is automatically disabled - which is good. But then when I unplug the headphones, it is not always enabled again. So sometimes I end up without any sounds. This is very critical, because in this case I won't hear neither calls nor alarm clock - nothing.
Also the Function Validation app confirms that the loud speaker doesn't work.
Two ways to bring the speaker back to life: (1) reboot the phone; (2) plug and unplug the headphones again.
I am using SmartConnect with "Music on the go" profile - that is, when I plug my headphones in, it automatically starts Walkman and starts playing. When I unplug the headphones, it stops Walkman. These actions always happen - even when the speaker is not enabled. So the phone "notices" that I unplug the headphones. Therefore it doesn't seem to be a hardware issue (like if the headphone input is broken, so the device doesn't detect when headphone disconnects). It seems to be a software issue.
I also tried to disable the SmartConnect profile - still the issue remains.
I noticed that the issue happens when I unplug my headphones close to the end of the track (within last 10 seconds). But I am not sure that this observation is 100% correct - need to test more.
Did anybody experience this behavior?
