Hello,<br>
<br>
I'm using the equalizer sink for PulseAudio 4.0 under SolydK so that
my subwoofer emits sound only about 80 Hz and below in my 5.1 sound
system. (I wanted to try another solution to do this, as I wrote in
my post on Stackexchange <a href="http://unix.stackexchange.com/questions/138810/low-pass-filter-on-lfe-using-pulseaudio" target="_blank">here</a>,
but it wasn't successful.) Also, I'm using gstreamer.<br>
<br>
One problem is that every time I reboot, the settings in qpaeq don't
seem to take effect. Even if I open qpaeq and start moving the
scales, the change is not reflected in the sound at all. However, if
I enter <i>pulseaudio -k</i> and then <i>pulseaudio -D</i> in the
terminal, I can hear that equalization is applied.<br></div></blockquote><div> </div><div>Hi,<br><br></div><div>Re the equalizer, this sounds very odd, perhaps somehow one of the modules is not loaded when your desktop environment starts pulse? Could you try using pacmd list-modules and look for module-dbus-protocol and module-equalizer-sink on such conditions? Are you sure applications are being routed through the equalizer? A good way to check is pavucontrol.<br>

Another problem is that when the equalized sink is the default sink,
sound stutters when watching a video on YouTube with Firefox and
Flash or playing an mp3 with VLC. However, there is stuttering only
at the beginning or the end of playing (when I select stop) or
jumping to a particular position while playing a video in SMplayer,
Mplayer, VLC, or listening to music in Clementine.<br></div></blockquote><div><br></div><div>These are buffering issues manifesting with flash and others with events causing a rewind (start/stop/seek) when multiple sources are active - my advice for now is to not use flash and the equalizer together and instead have flash content go directly to the device sink. The rewind issues on multiple sources is another long standing issue to fix but if you do not have multiple sources active, it will not manifest. For what its worth, they are problems I want to look into to characterize better and fix but I am months out from having the luxury of time to do it.<br>
