[Bug 672420] Re: Changing volume to 0% breaks channel ballance
The point is gnome-media seem does not keep the setting of volume e.g. when you increase the volume to over 100% , log out and login , you will find the volume change to 100% -- Changing volume to 0% breaks channel ballance https://bugs.launchpad.net/bugs/672420 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-media in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 672420] Re: Changing volume to 0% breaks channel ballance
Can we fix this bug with ballance? Or it must be fixed in pulseaudio? And what can we do for add support surround4.1, 5.1, 7.1 and other configurations? Because configuring different volumes per channel in surround systems needs more often than in only stereo system. I think better is to store each volume per-channel, instead of ballance. I have create the bug in pulseaudio about this: http://pulseaudio.org/ticket/874 ** Bug watch added: PulseAudio sound server #874 http://pulseaudio.org/ticket/874 ** Also affects: gnome-media via http://pulseaudio.org/ticket/874 Importance: Unknown Status: Unknown -- Changing volume to 0% breaks channel ballance https://bugs.launchpad.net/bugs/672420 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-media in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 672420] Re: Changing volume to 0% breaks channel ballance
Using 4 controls : Volume , Balance, Fade and Bass to control six or
eight channels is not easy especially when gnome-media cannot
save/restore the settings of this four controls
This bug is in pa_cvolume_set_balance() since left and right will be zero when
you set the volume to 0%
655 get_avg_lr(map, v, left, right);
656
657 m = PA_MAX(left, right);
658
659 if (new_balance = 0) {
660 nright = (new_balance + 1.0f) * m;
661 nleft = m;
662 } else {
663 nleft = (1.0f - new_balance) * m;
664 nright = m;
665 }
666
667 for (c = 0; c map-channels; c++) {
668 if (on_left(map-map[c])) {
669 if (left == 0)
670 v-values[c] = nleft;
671 else
672 v-values[c] = (pa_volume_t) PA_CLAMP_VOLUME(((uint64_t)
v-values[c] * (uint64_t) nleft) / (uint64_t) left);
673 } else if (on_right(map-map[c])) {
674 if (right == 0)
675 v-values[c] = nright;
676 else
677 v-values[c] = (pa_volume_t) PA_CLAMP_VOLUME(((uint64_t)
v-values[c] * (uint64_t) nright) / (uint64_t) right);
678 }
679 }
680
pa_cvolume_get_balance() return 0 when
623 if (left == right)
624 return 0.0f;
