Created attachment 112054 [details] Sound indicator and alsamixer in one picture Hi, I'm using a Bose Companion 5 set of speakers, but I'm having a problem with setting the volume in pulseaudio. In 'alsamixer', the volume indicator is correct, but in the control center and or sound indicator, the volume is incorrect. If I remember correctly(this has been happening for years, but I stopped using my speakers), when I was using `mocp', 90% in pulseaudio would be where the volume starts. 91% was 10%, 92% was 20%, etc. etc. Any known workaroudns in the meantime? Thanks,

Created attachment 112083 [details] lspci verbose4 Here is lspci -vvvv (It doesn't seem to contain anything about the speakers?) I wasn't sure if you wanted me to also post it here, since your second comment just said lspci -vvvv. Thanks
Created attachment 112084 [details] root lspci verbose 4 I probably should have run that as root. Here's the root version.
your usb audio only support 6 channel and has pcm playback volume control with very small dB range from -3.12 dB to 0dB the work around is ignore dB range by specify ignore_dB=1 http://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Modules/#index53h3 USB Mixer: usb_id=0x05a71020, ctrlif=0, ctlerr=0 Card: Bose Corporation Bose USB Audio at usb-0000:00:14.0-1, full speed Unit: 3 Control: name="PCM Playback Volume", index=0 Info: id=3, control=2, cmask=0x0, channels=1, type="S16" Volume: min=-801, max=-1, dBmin=-312, dBmax=0 Unit: 3 Control: name="PCM Playback Switch", index=0 Info: id=3, control=1, cmask=0x0, channels=1, type="INV_BOOLEAN" Volume: min=0, max=1, dBmin=0, dBmax=0 post output of your usb audio device lsusb -vvvv
Created attachment 112086 [details] lsusb -vvvv run as root Mm. Sorry about that. I misread it as lspci.
ignore_dB=1 works a treat. Thanks a lot! :) Should I close the kernel.org bug report? Or is it still valid?(i.e sending the wrong dB) Thanks
control.3 { iface MIXER name 'PCM Playback Volume' value 100 comment { access 'read write' type INTEGER count 1 range '0 - 100' dbmin -312 dbmax 0 dbvalue.0 0 } } it only aupport 6 channels and dB range need to be fixed since -3.12 seem not enough Bus 001 Device 012: ID 05a7:1020 Bose Corp.
