Issue description
UserAgent: Mozilla/5.0 (X11; CrOS x86_64 9592.42.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.52 Safari/537.36
Platform: 9592.42.0 (Official Build) beta-channel cave
Steps to reproduce the problem:
1. connect a bluetooth speaker
2. use it with other devices throughout the day
3.
What is the expected behavior?
no 100% load on CPU
What went wrong?
cras process uses 100% cpu emitting heat and draining battery
repeated calling:
ppoll([{fd=19, events=POLLIN}, {fd=21, events=POLLIN}, {fd=24, events=POLLIN}, {fd=3, events=POLLIN}, {fd=12, events=POLLIN}, {fd=17, events=POLLIN}, {fd=18, events=POLLIN}, {fd=15, events=POLLIN}, {fd=13, events=POLLIN}, {fd=27, events=POLLIN}], 10, NULL, NULL, 8) = 1 ([{fd=27, revents=POLLERR|POLLHUP}])
clock_gettime(CLOCK_MONOTONIC_RAW, {267188, 846186799}) = 0
immediately enters 100% load state after connecting the device and/or killing the process.
Will try to catch the full trace log later.
Did this work before? N/A

"2. use it with other devices throughout the day". What were the other devices?

I will be able to check if it is still the issue the next week; Steps to reproduce (I suspect other reproducers possible): 1. have a BT speaker that supports multiple devices (e.g. JBL Xtreme) 2. connect the speaker to chromebook 3. play some sounds 4. use another device to play music with BT speaker -. Observe the CPU load on chromebook gone to 100%, chromebook overheated and powered down -. restarting cras does not help to fix the issue, the sound output to BT speaker is laggy but working -. to fix the issue you must switch off BT on chromebook -. whenever BT is back again (if the chromebook survived overheating) - the issue returns immediately after chromebook connects to the speaker

I tried Bose QuietComfort35 with eve M64 tot (synced on last week IIRC). I could reproduce this.
