2024-05-12ALSA: scarlett2: Increase mixer range to +12dBGeoffrey D. Bennett1-4/+5
The values loaded into the mixer are 16-bit values, with 8192 representing 0dB, going up to a current maximum of 16345 (+6dB). All supported interfaces have no problem going up to 32612 (+12dB), so update SCARLETT2_MIXER_MAX_DB and scarlett2_mixer_values[] to allow for this. Tested with: - Scarlett 2nd Gen 6i6, 18i8, 18i20 - Scarlett 3rd Gen 4i4, 8i6, 18i8, 18i20 - Scarlett 4th Gen Solo, 2i2, 4i4 - Clarett+ 2Pre, 4Pre, 8Pre - Vocaster One and Two Signed-off-by: Geoffrey D.

Add S/PDIF Source/Digital I/O Mode selection controls for the Scarlett 3rd Gen 18i8/18i20 and Clarett 4Pre/8Pre interfaces. These models have both coax S/PDIF and optical inputs, and the optical inputs are switchable between being used as S/PDIF and ADAT inputs. The Scarlett 3rd Gen 18i20 also has a "Dual ADAT" mode for 8-channel audio at 88.2/96kHz. Signed-off-by: Geoffrey D.

The Focusrite Scarlett Gen 4 Solo has Air and Phantom Power controls on analogue input #2 (the Gen 3 Solo had these controls on analogue input #1). Add air_input_first and phantom_first device info options to cater for this. These options are similar to the level_input_first option that was added for the Gen 3 Solo, but these new options do not require adjusting the index of the control. Signed-off-by: Geoffrey D.

2023-12-29ALSA: scarlett2: Remove repeated elem->head.mixer referencesGeoffrey D. Bennett1-3/+4
Use a local variable *mixer rather than repeating elem->header.mixer in scarlett2_direct_monitor_ctl_get() and scarlett2_meter_ctl_get(). Signed-off-by: Geoffrey D.

2023-12-29ALSA: scarlett2: Split direct_monitor out from monitor_otherGeoffrey D. Bennett1-131/+158
The notification value for monitor_other on the large interfaces is the same as the notification value for direct_monitor on the 3rd Gen small interfaces. Add a separate scarlett3a_notifications array and split out the direct_monitor handling. Signed-off-by: Geoffrey D.

2023-12-29ALSA: scarlett2: Split input_other into level/pad/air/phantomGeoffrey D. Bennett1-58/+140
Gen 2/3 devices have a single notification value for "input other" changes. Gen 4 has separate notification values for level, pad, air, and phantom power changes. Therefore, split the input_other_updated field and the scarlett2_update_input_other() function into the four components so that they can be handled separately later. Signed-off-by: Geoffrey D.

2023-12-29ALSA: scarlett2: Rename db_scale_scarlett2_gain to volumeGeoffrey D. Bennett1-3/+3
db_scale_scarlett2_gain is the TLV for the output volume controls. Gen 4 has software-controllable input gain controls, so rename this to db_scale_scarlett2_volume so we can use that name for the inputs. Signed-off-by: Geoffrey D.

2023-12-29ALSA: scarlett2: Allow for interfaces without per-channel volumeGeoffrey D. Bennett1-28/+40
Currently-supported interfaces with a mixer have per-channel volume controls, but this changes in Gen 4. Add a check so that the Playback Volume and associated controls don't get created unless the SCARLETT2_CONFIG_LINE_OUT_VOLUME config item is present. Signed-off-by: Geoffrey D.

2023-12-29ALSA: scarlett2: Remove line_out_hw_vol device info entryGeoffrey D. Bennett1-49/+96
By splitting config set gen2 into gen2a/b (for 6i6/18i8 vs 18i20), and gen3b into gen3b/c (for 4i4/8i6 vs 18i8/18i20), we can use scarlett2_has_config_item() instead of the per-device line_out_hw_vol. As Gen 4 has a master volume control but no SW/HW switches, check for both SCARLETT2_CONFIG_MASTER_VOLUME and SCARLETT2_CONFIG_SW_HW_SWITCH as needed, even though for Gen 2 and Gen 3 the former implies the latter.

2023-12-29ALSA: scarlett2: Split dim_mute_update from vol_updatedGeoffrey D. Bennett1-21/+42
Scarlett Gen 2 and Gen 3 devices combine volume and dim/mute notifications. The Scarlett 4i4 Gen 4 has volume change notification but no dim/mute control so split dim_mute_update out from vol_update.

2023-12-29ALSA: scarlett2: Remove struct scarlett2_usb_volume_statusGeoffrey D. Bennett1-69/+61
The struct scarlett2_usb_volume_status matched the config space layout of a few volume controls that could be read together and were in fixed locations between Gen 2 and Gen 3 devices. Gen 4 devices have removed, moved, and new related controls, so this needs to be cleaned up. By adding SCARLETT2_CONFIG_MASTER_VOLUME (the only config item that didn't already have its own entry, because it is read-only), we can remove: - struct scarlett2_usb_volume_state, - #define SCARLETT2_USB_VOLUME_STATUS_OFFSET, and - scarlett2_usb_get_volume_status() and replace with calls to scarlett2_usb_get_config().
