Description 3draven 2013-10-30 02:18:54 UTC 
To repeat the bug should:
1. If shift the balance between the output channels in the the left direction by 50%.
2. Try typing the command
pactl set-sink-volume 0 -- -10%
pactl set-sink-volume 0 +10%

As a result, +10 will be decreased volume! Just when shifted the balance of the channels may be other unexpected results adjustment of the sound.

Comment 4 Raymond 2013-11-01 15:53:51 UTC 
but your speaker volume are at 100% on both output

headphone and HDMI are not plugged and your USB audio have no playback volume control

Simple mixer control 'Speaker',0
  Capabilities: pvolume pswitch penum
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 42
  Mono:
  Front Left: Playback 42 [100%] [0.00dB] [on]
  Front Right: Playback 42 [100%] [0.00dB] [on]


post output of

pactl list sinks

after you change the balance and volume
Comment 5 3draven 2013-11-01 17:23:55 UTC 
Balance 25% to left
Volume 50%

Comment 7 3draven 2013-11-01 17:30:16 UTC 
I must clarify that I am using the following commands

For jack audio (pulse->jack)

pactl set-sink-volume jack_out -- -10%

For clean pulseaudio:

pactl set-sink-volume 0 -- -10%
or sink 1
Comment 8 Raymond 2013-11-02 06:19:12 UTC 
do you select jack_out in sound preference as default sink when you change the balance and volume ?

seem pulseaudio only use software volume for jack_out

how do pulseaudio know the jack server use which sink or source since you can specify playback and capture on different alsa cards/devices ?

your jack server can even use alt analog device of vt1802 (independent headphone) or your USB emu 0204

Comment 9 3draven 2013-11-02 13:30:02 UTC 
I switch off EMU device and jack server. To simplify the problem.
1. set balance to 25% left
2. pactl set-sink-volume 1 +10%
3. sound decreased

http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/utils/pactl.c

if volume of each channel can really be adjusted by percentage, it should not use pa_volume_avg

static void volume_relative_adjust(pa_cvolume *cv) {
    pa_assert((volume_flags & VOL_RELATIVE) == VOL_RELATIVE);

    /* Relative volume change is additive in case of UINT or PERCENT
     * and multiplicative for LINEAR or DECIBEL */
    if ((volume_flags & 0x0F) == VOL_UINT || (volume_flags & 0x0F) == VOL_PERCENT) {
        pa_volume_t v = pa_cvolume_avg(cv);
        v = v + volume < PA_VOLUME_NORM ? PA_VOLUME_MUTED : v + volume - PA_VOLUME_NORM;
        pa_cvolume_set(cv, 1, v);
    }
