A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1909> ====================================================================== Reported By: andersin Assigned To: Clemens Ladisch ====================================================================== Project: ALSA - driver Issue ID: 1909 Category: USB - usb-audio Reproducibility: always Severity: text Priority: normal Status: assigned Distribution: Kernel Version: ====================================================================== Date Submitted: 03-11-2006 16:33 CET Last Modified: 08-04-2006 18:59 CEST ====================================================================== Summary: Labelling of controls for SB Extigy is confusing Description: The controls for the SB Extigy are all labelled as Master. The names should reflect the channel(s) that they control. Amixer shows this information (albeit its mapping of controls to actual channels is off). Additionally a Master 1 control exists that changes the volume of all channels. ====================================================================== ---------------------------------------------------------------------- Raymond - 08-03-06 11:43 ---------------------------------------------------------------------- Syntax: SOURCE [DIRECTION] FUNCTION The following controls appear in capture view of alsamixer because it miss the 'Playback' direction Simple mixer control 'Bass',0 Capabilities: volume volume-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 96 Mono: 48 [50%] Simple mixer control 'Treble',0 Capabilities: volume volume-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 96 Mono: 48 [50%] The following control should only appear in capture view of alsamixer, because the control name did not follow Syntax: SOURCE [DIRECTION] FUNCTION Simple mixer control 'Capture Input Source',0 Capabilities: enum Items: 'Input 0' 'Mic' 'Mixer' Item0: 'Input 0' Simple mixer control 'Digital In',0 Capabilities: volume volume-joined pswitch pswitch-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 200 Mono: 200 [100%] Playback [on] These control also not follow the syntax.

Please post the output of "lsusb -v" for this device.
