Subject: [PATCH v2 2/2] ALSA: usb-audio: Simplify DJM mixer quirks
Date: Thu, 4 Feb 2021 03:44:32 +0000 [thread overview]
Message-ID: <20210204034432.15504-3-livvy@base.nu> (raw)
In-Reply-To: <20210128160338.dac4vrj7wjiykcxm@base.nu>
More DJM devices are due to be addded to Mixer quirks. This removes some
of the device-specific duplication by doing the following:
1. Don't specify wIndex on each value, just specify it on the
control.
2. Lookup the control labels dynamically based on the wValue.
3. Shorten the namespace prefix to "snd_djm_"

/*
* Pioneer DJ DJM Mixers
*
* These devices generally have options for soft-switching the playback and
* capture sources in addition to the recording level. Although different
* devices have different configurations, there seems to be canonical values
- * for specific capture/playback types:
- *
- * Capture | Playback
- * ================================|===========
- * Control Tone Line 0x00 | Ch1 0x00
- * Control Tone CD/Line 0x01 | Ch2 0x01
- * Control Tone Phono 0x03 | Aux 0x04
- * Post Fader 0x06 |
- * Cross Fader A 0x07 |
- * Cross Fader B 0x08 |
- * Mic 0x09 |
- * Aux 0x0d |
- * Rec_Out 0x0a |
- * None 0x0f |
- * Ch1 Post Fader 0x11 |
- * Ch2 Post Fader 0x12 |
- *
- * The wValue for configuring playback/capture type also contains the channel
- * the input type should apply to:
- * CHANNEL NUMBER 0xff00
- * INPUT TYPE 0x00ff
- * e.g. Channel 2 set to 'Control Tone Phono' will have wValue 0x0203
- *
- * The wIndex values are below:
- * CAPTURE 0x8002
- * CAPTURE LEVEL 0x8003
- * PLAYBACK 0x8016
- *
+ * for specific capture/playback types: See the definitions below.
