GUI Based

Utilities - dsbmixer
Source Path - /usr/ports/audio/dsbmixer/

Features

Before checking audio feature go through the reference link at the end
Default pcm0 device selected by a audio driver, user can switch the device by running the below comments

test:~$ mixer -d pcm*

Equalization setting

Enable the equalization on sound system, add the below line in the configuration file

test:~$ vim /boot/loader.conf
hint.pcm.0.eq=1

` * Note: Default 0 is setted to equalizer, after adding below line reboot the system. Base & treble controls added to the sound device

Example :

test:~$ mixer
   pcm0:mixer: <Conexant CX20590 (Analog 2.0+HP/2.0)> on hdaa0 (play/rec) (default)
      vol       = 0.53:0.53     pbk
      bass      = 0.50:0.50     pbk
      treble    = 0.50:0.50     pbk
      pcm       = 1.00:1.00     pbk
      speaker   = 1.00:1.00     pbk
      mic       = 0.00:0.00     rec
      rec       = 0.01:0.01     pbk
      monitor   = 0.42:0.42     rec src

Low latency setting

Default value is 2, based on requirement adjust the latency value . Support (0-10)

test:~$ sysctl hw.snd.latency=0

Profile is optimized for the lowest possible latency. Support (0, 1)

test:~$ sysctl hw.snd.latency_profile=0

To Adjust the Volume

min 0 to max 100 can set on device
For a same user can set other feature level of the deivce using “rec”, “mic”, “speaker”.

test:~$ mixer vol=+5%

pcm0:mixer: <Conexant CX20590 (Analog 2.0+HP/2.0)> on hdaa0 (play/rec) (default)
      vol       = 0.58:0.58     pbk
      pcm       = 1.00:1.00     pbk
      speaker   = 1.00:1.00     pbk
      mic       = 0.00:0.00     rec
      rec       = 0.01:0.01     pbk
      monitor   = 0.42:0.42     rec src

To Record Audio

test:~$ ffmpeg -f oss -i /dev/dsp0 output.wav
