pa 0.9.12 uses the decibel information exported by the sound card and extends the volume range if necessary in software. Could you please dump "amixer -c 0 scontents"? % amixer -c 0 scontents Simple mixer control 'Master',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 14 [45%] [-25.50dB] [on] Front Right: Playback 14 [45%] [-25.50dB] [on] Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [off] Simple mixer control 'IEC958 Default PCM',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] Simple mixer control 'Capture',0 Capabilities: cvolume cswitch Capture channels: Front Left - Front Right Limits: Capture 0 - 15 Front Left: Capture 0 [0%] [0.00dB] [off] Front Right: Capture 0 [0%] [0.00dB] [off] Simple mixer control 'Input Source',0 Capabilities: cenum Items: 'Mic' 'Front Mic' Item0: 'Mic' The mixing issue should be fixed now in upstream git commit ea82dec. I will push this into rawhide soon. The offset in the percentage values is because PA now always uses the dB info and ignores the integer scale of the sound card. We want to present a unified user interface to the user where the mapping between volume percentages and dB is always the same. Thus, we trust only the dB and do the percentage transformation ourselves. Fixed in 0.9.13-1 Confirmed fixed in 0.9.13-1, thanks... |
