<div dir="ltr"><p class="gmail-_1qeIAgB0cPwnLhDF9XSiJM">I have a question about how
Pulseaudio functions between sound hardware and applications in Linux
and spins. I noticed both Firefox and Chromium internally report many hardware details, including the sound output chipset and connected Bluetooth devices (with unique identifiers).</p><p class="gmail-_1qeIAgB0cPwnLhDF9XSiJM">I
assumed that Pulseaudio behaved as an opaque interface between software
and hardware, in other words, applications send and receive inputs and
outputs to Pulseaudio, which in turn mixes and exclusively communicates
with sound hardware. Instead, I have noticed many instances where
browsers exhibit unintended control over sound outputs, for instance,
playing a youtube video will sometimes abruptly disconnect a Bluetooth
headset.</p><p class="gmail-_1qeIAgB0cPwnLhDF9XSiJM">Is this behavior by design? Is it possible to sandbox applications from the sound hardware so that they only communicate and have a view of Pulseaudio, rather than the underlying hardware? Could something like Jack accomplish this?</p></div>
