Bug#801428: pulseaudio: on stock workstation with normal left/right speakers, bass is stripped, unless using headphones jack

[Stephen Dowdy]

Felipe,

progress :)

sdowdy at resonance$ aptitude search --disable-columns -F '%p %v' ~ilibpulse
~ipulseaudio | column -t
libpulse-mainloop-glib0  7.0-1~bpo8+1
libpulse0                7.0-1~bpo8+1
libpulsedsp              7.0-1~bpo8+1
pulseaudio               7.0-1~bpo8+1
pulseaudio-utils         7.0-1~bpo8+1

I installed these and rebooted, and it appears the bass is working with
this setup, at least for my aging ears. (i don't have a frequency analyzer,
just listening to music through my crummy desktop speakers)

If i switch the port to "headphones" in pavucontrol, it continues to play
out line-out (where i have the jack for the external speakers), but the
volume drops from 68% to 57%. (it was altering the volume a slight amount
before, and maybe there's a save volume on a per-port basis that is being
recalled?)  Anyway, the equalization doesn't appear to be altered, so the
bass stays consistent, which is good.

In 'veromix', if i add the multi-band EQ plugin, it has no effect on sound,
however.   I was only playing with that earlier in an effort to determine
what was wrong with the bass.  probably not something i'll be playing with
personally, but thought i'd add that bit.  (i don't know if it was working
or not in stock pulseaudio).

I have not re-installed stock packages, rebooted, and confirmed that the
bass "disappearance" bug reverts.   I'll check that later.

thanks,
--stephen
