Equalizer setting is forgotten until PA is restarted and sound stutters

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

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 here 
<http://unix.stackexchange.com/questions/138810/low-pass-filter-on-lfe-using-pulseaudio>, 
but it wasn't successful.) Also, I'm using gstreamer.

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 
/pulseaudio -k/ and then /pulseaudio -D/ in the terminal, I can hear 
that equalization is applied.

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.

You can see at the end of this message the content of my default.pa 
(placed in ~/.pulse).

Any help would be appreciated.

Yours,
Zsolt
