* ALSA: scarlett2: Define the maximum preamp input gain per-config-setGeoffrey D. Bennett2024-04-181-8/+12
| | | | | | | | | | Remove the #define SCARLETT2_MAX_GAIN_DB and replace with a per-config-set TLV as the Vocaster has a maximum gain of 70dB vs the 4th Gen 69dB. Signed-off-by: Geoffrey D.

* ALSA: scarlett2: Add additional input configuration parametersGeoffrey D. Bennett2024-04-181-56/+80
| | | | | | | | | | | | | | | | The 4th Gen Scarlett interfaces added software-controllable input gain along with channel select, channel link, auto-gain, and "safe" mode. Vocaster has software-controllable input gain and auto-gain but not channel select, channel link, or safe mode. Add a device info field safe_input_count to indicate how many channels have a safe mode control, and use the presence of the input select and input link switch configuration parameters to determine if those controls should be created.

* ALSA: scarlett2: Add pbuf field to struct scarlett2_configGeoffrey D. Bennett2024-04-181-39/+46
| | | | | | | | | | | scarlett2_usb_set_config() was using size = 0 as a signal to use the parameter buffer. Replace that with an explicit indication (pbuf = 1), as the upcoming Vocaster support has a config item written via the parameter buffer with size = 1 rather than the implicit size of 8.

* Revert "ALSA: usb-audio: Name feature ctl using output if input is PCM"Takashi Iwai2024-03-171-35/+14
| | | | | | | | | | | | | | | | | | | This reverts commit 1601cd53c7e3197181277326dbfc131d20a74e46. This fix is applied globally to all devices, and it may change the existing control names. When the devices are managed with the fixed configuration like UCM, such control name mismatch may lead to significant regressions. For avoiding that kind of regression, we would need to apply such changes conditionally, but it'd take time to settle down. While the original fix is a good thing in general, in order to address the regression, let's revert the change for now.

* ALSA: usb-audio: Name feature ctl using output if input is PCMKenny Levinsen2024-03-041-14/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building feature controls from a unit without a name, we try to derive a name first from the feature unit's input, then fall back to the output terminal. If a feature unit connects directly to a "USB Streaming" input terminal rather than a mixer or other virtual type, the control receives the somewhat meaningless name "PCM", even if the output had a descriptive type such as "Headset" or "Speaker". Here is an example of such AudioControl descriptor from a USB headset which ends up named "PCM Playback" and is therefore not recognized as headphones by userspace: AudioControl Interface Descriptor: bLength 12 bDescriptorType 36 bDescriptorSubtype 2 (INPUT_TERMINAL) bTerminalID 4 wTerminalType 0x0101 USB Streaming bAssocTerminal 5 bNrChannels 2 wChannelConfig 0x0003 Left Front (L) Right Front (R) iChannelNames 0 iTerminal 0 AudioControl Interface Descriptor: bLength 9 bDescriptorType 36 bDescriptorSubtype 3 (OUTPUT_TERMINAL) bTerminalID 5 wTerminalType 0x0402 Headset bAssocTerminal 4 bSourceID 6 iTerminal 0 AudioControl Interface Descriptor: bLength 13 bDescriptorType 36 bDescriptorSubtype 6 (FEATURE_UNIT) bUnitID 6 bSourceID 4 bControlSize 2 bmaControls(0) 0x0002 Volume Control bmaControls(1) 0x0000 bmaControls(2) 0x0000 iFeature 0 Other headsets and DACs I tried that used their output terminal for naming only did so due to their input being an unnamed sidetone mixer. Instead of always starting with the input terminal, check the type of it first. If it seems uninteresting, invert the order and use the output terminal first for naming. This makes userspace recognize headsets with simple controls as headphones, and leads to more consistent naming of playback devices based on their outputs irrespective of sidetone mixers.

* ALSA: usb-audio: More relaxed check of MIDI jack namesTakashi Iwai2024-02-151-48/+25
| | | | | | | | | | | | | | | | | | | The USB audio driver tries to retrieve MIDI jack name strings that can be used for rawmidi substream names and sequencer port names, but its checking is too strict: often the firmware provides the jack info for unexpected directions, and then we miss the info although it's present. In this patch, the code to extract the jack info is changed to allow both in and out directions in a single loop. That is, the former two functions to obtain the descriptor pointers for jack in and out are changed to a single function that returns iJack of the corresponding jack ID, no matter which direction is used. It's a code simplification at the same time as well as the fix.

* ALSA: usb-audio: Ignore clock selector errors for single connectionAlexander Tsoy2024-02-011-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For devices with multiple clock sources connected to a selector, we need to check what a clock selector control request has returned. This is needed to ensure that a requested clock source is indeed selected and for autoclock feature to work. For devices with single clock source connected, if we get an error there is nothing else we can do about it. We can't skip clock selector setup as it is required by some devices. So lets just ignore error in this case. This should fix various buggy Mackie devices: [ 649.109785] usb 1-1.3: parse_audio_format_rates_v2v3(): unable to find clock source (clock -32) [ 649.111946] usb 1-1.3: parse_audio_format_rates_v2v3(): unable to find clock source (clock -32) [ 649.113822] usb 1-1.3: parse_audio_format_rates_v2v3(): unable to find clock source (clock -32) There is also interesting info from the Windows documentation [1] (this is probably why manufacturers dont't even test this feature): "The USB Audio 2.0 driver doesn't support clock selection. The driver uses the Clock Source Entity, which is selected by default and never issues a Clock Selector Control SET CUR request."

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many devices with a single alternate setting do not have a Valid Alternate Setting Control and validation performed by validate_sample_rate_table_v2v3() doesn't work on them and is not really needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 086b957cc17f5 ("ALSA: usb-audio: Skip the clock selector inquiry for single connections") we are already skipping clock selector inquiry if only one clock source is connected, but we are still sending a set request.

| | | | | | | | | | | | | Early firmware for the Scarlett Gen 4 devices has sufficient differences that it is better to enforce a minimum firmware version than to try and work around those differences. Add a minimum firmware version field to the device info struct, and display a message if the firmware version is too old. Only create the Firmware Version and MSD (optional) controls in this case.

| | | | | | | | | | | | | | Gen 2/3 interfaces would only use 0/1 values for input level and phantom power switch controls.

| | | | | | | | | | | | | | | | | | Writing Scarlett Gen 4 parameters differs from Gen 2 and Gen 3: - the values are written into a shared write location - the values are only byte-sized - the read locations now extend beyond 0xFF - a separate NVRAM save step is no longer required This patch implements that alternate write style, triggered by setting the config item size field to zero.
