choosing different sound input and output devices

[Marek Zarychta]

Dear subscribers,

I tried to deploy the Chromium browser run on FreeBSD CURRENT to work 
with Microsoft Teams and it almost works fine except for audio settings. 
To use USB microphone I have changed sysctl hw.snd.default_unit and was 
able to use my microphone, but it broke the playback. Is it possible to 
use different audio input and output devices ? Any clues, especially 
with regard to www/chromium will be appreciated.


Perhaps the list I am posting this question on was not carefully chosen, 
but haven't found any sound/audio specific mailing lists.


With kind regards,

Hi,

Virtual OSS from ports can do this for you. Now also via the command 
line tool virtual_oss_cmd

Just out of curiosity: Going to chrome://settings/content/microphone
won't allow you to select the input device to use? (it seems like having
the select box in there is platform specific).

Best,
Michael

Thank you for the clue. I should have put more effort into finding this 
on FreeBSD Wiki pages.


With Virtual OSS  (audio/virtual_oss) installed and configured 
teleconferencing on Microsoft Teams platform works fine with Chromium 
native FreeBSD package (www/chromium) installed - as far as I have 
tested it.

-p and -B are not related.

-p deals with changes needed for a correct run of installworld (see above).

-B uses a freshly built world to speed up the tree comparison; although no
flags work fine here as well, so -B is not necessarily required.


Technically -B speeds up generating the tree to compare against as it assumes
/usr/obj is up to date and uses that instead of rebuilding some files
generated by buildworld normally.  The actual tree comparison isn't affected.

Hmm, how did you initially install this machine?  Release images should
generally include a pre-populated /var/db/etcupdate so that etcupdate
works.  If you don't have one of those, you will have to perform an
initial bootstrap of etcupdate (only once) by running 'etcupdate extract'.
If you do this before you update /usr/src then 'etcupdate' will later
work fine.  If you are doing this after you have already updated
/usr/src, you will need to run 'etcupdate diff' after 'etcupdate extract'
and fix any unexpected local differences in the generated patch, e.g.
by copying files from /var/db/etcupdate/current/etc to /etc.  Once
you have done this, 'etcupdate' will work fine on the next upgrade.

However, I'm curious how you didn't get the etcupdate bootstrap when
you initially installed.
