Description a3987928 (reporter) 2014-05-19 14:46:23 UTC
SOFTWARE VERSION: 
21.2011.38-1Smaemo6.1

EXACT STEPS LEADING TO PROBLEM: 
1. Answer phonecall or make a call
2. Have a couple of minutes conversation.
3. End the call.

EXPECTED OUTCOME: 
No cpu usage for pulseaudio while the phone is not used.

ACTUAL OUTCOME: 
pulseaudio process stuck permanently active at 24% cpu
rate.

REPRODUCIBILITY: 
nearly 5/10

EXTRA SOFTWARE INSTALLED:

open media player, cutetube

OTHER COMMENTS:

"powertop" , before killing pulseaudio, shows:

37% interrupt : DMA
34% interrupt : i2c_omap
21% interrupt : gp timer
2% i interrupt : mmc1

and "top" shows cpu usage around 24% for /usr/bin/pulseaudio -- system
--high-priorit (user=pulse)

killing tonegend is not killing pulseaudio like said in similar closed bugs

similar issue reported for N9 on tmo
