I can't get web browsers to recognise USB microphones.
USB output (e.g. to my headphones) is OK.
USB input (e.g. from the microphone part of the headphones) is not.
Any suggestions?
Firefox uses "pulse-rust" cubeb backend *by default* if "pulseaudio"
package is installed. getUserMedia is supposed to preset a dropdown menu
to select a microphone. Make sure pulseaudio actually recognizes the
desired microphone e.g., debug via "pactl list" and "parec".
I don't have a mic but, looking at the code, only pulse-rust or pulse
backends on Linux/FreeBSD support selecting non-default audio device.
It maybe possible to use other backends but if audio device used for
output and input are different that'd require routing defaults which can
be done via config file (e.g., ~/.asoundrc) or externally via virtual_oss.
pcm3: <USB audio> (play/rec) default
pcm4: <USB audio> (rec)
Are these distinct physical devices?
Yes.
hw.snd.default_unit: 3
Have you tried using 4?
I did, but decided that the device previously at 4 (Alctron USB700
<https://www.alctron-audio.com/EN/microphones/USB/USB700.html>) probably
has a hardware fault.
Worth noting: if I attempt to suspend the system whilst the device at 3
(SteelSeries Siberia 350 headphones with integral microphone
<https://steelseries.com/gaming-headsets/siberia-350>) is physically
connected, suspend sometimes fails; it becomes necessary to force off
the computer.
If I start the system with the headphones connected, then the microphone
at 3 is usable at e.g.
<https://www.podcastinsights.com/online-mic-test/> and
<https://talky.io/> (see <https://i.imgur.com/Ch3SuZn.png>) but not in
Microsoft Teams.
If I disconnect the headphones (to minimise the risk of failure to
suspend), then reconnect, the system seems unable to reuse the
headphones (see <https://i.imgur.com/8Of5MUK.png>); a restart is required.
In Microsoft Teams, neither 2 nor 3 is detected; there's only 1 (see
<https://i.imgur.com/13HmxKi.png>) and after allowing use of /dev/dsp1
it 'disappears', leaving only the camera in use (head of
<https://i.imgur.com/k5ak2jL.png>).
