I'm seeing the same problem with my Dell touchpad since upgrading to
16.04. /proc/bus/input/devices shows my touchpad as:
I: Bus=0011 Vendor=0002 Product=0007 Version=01b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input5
U: Uni
Public bug reported:
When playing sound from an application that uses libao on Ubuntu 12.04
(for example, pianobar), it blocks any other sound-playing application
from playing audio (for example, Firefox on YouTube). A little digging
showed that /etc/libao.conf sets default_driver=alsa, changing
Happens on my x86_64 system, too. Ubuntu 11.04, snd_hda_intel driver.
