Have you checked your mixer settings? The command "mixer" provided
by the OS can do this. Example:
Mixer vol is currently set to 75:75
Mixer pcm is currently set to 75:75
Mixer line is currently set to 0:0
Mixer mic is currently set to 0:0
Mixer cd is currently set to 0:0
Mixer rec is currently set to 0:0
Mixer igain is currently set to 0:0
Mixer monitor is currently set to 0:0
Recording source: mic
If the system exposes more than one mixer to the OS, the -f flag
can be used to query and set the various mixers. See "man mixer"

Maybe Linux defaults to a different audio unit? Modern hardware
often does have more than one "sound card" (similar to mixers).
The sysctl "hw.snd.default_unit" can control which unit will be

Allow me to quote the relevant entries:
[rc.conf text/plain (911B)]
Do you have the playback problem from inside a IDE, or does the
problem also appear when you test audio "on bare metal"? How do
you test audio?
[loader.conf text/plain (1.3KB)]
It's okay to comment those entries because the GENERIC kernel
(which you are using as per "uname -a") does already include
the sound driver.

Always check the output of the following commands:
% dmesg | grep ^pcm
% cat /dev/sndstat
Verify that the correct sound driver has successfully been loaded.
Also have a look at the handbook section about sound:
