    This reverts commit 34dedd2a83b241ba6aeb290260313c65dc58660e.

    According to Realtek, volume FU works for line-in.

    I can confirm volume control works after device firmware is updated.

    The USB device (0x17aa:0x1046) that support Lenovo P620 rear panel
    line-in claim to support volume control, but it doens't seem to have an
    AMP, so when line-in volume lowers below 80, nothing gets recorded
    anymore.

    Disable the volume control to workaround the issue.

  • f8c11eb7d   ALSA: usb-audio: Add support for Lenovo ThinkStation P620 ... Browse Code »

    Lenovo ThinkStation P620 is like other TRX40 boards, is equipped with
    two USB audio cards.

    USB device (17aa:104d) provides functionality for Internal Speaker and
    Front Headset. It's UAC v2, so it supports insertion control (jack
    detection). However, when trying to get the connector status of the
    speaker, an error occurs:
    [ 5.787405] usb 3-1: cannot get connectors status: req = 0x81, wValue = 0x200, wIndex = 0x1000, type = 0

    Since the insertion control works perfectly for the headset, the error
    for speaker is probably casued by connecting internally. So let's relax
    the error for a bit if it's a speaker, and always reports it's connected.

    USB device (17aa:1046) is for rear Line-in, Line-out and Microphone.
    The insertion control works for all three jacks. However, there's an
    Function Unit that doesn't work:
    [ 5.905415] usb 3-6: cannot get ctl value: req = 0x83, wValue = 0xc00, wIndex = 0x1300, type = 4
    [ 5.905418] usb 3-6: 19:0: cannot get min/max values for control 12 (id 19)

    So turn off the FU to avoid the error.

    Also, add specific card name for both devices, so userspace can easily
    indentify both cards.

  • 7f5ad9c90   ALSA: usb-audio: Quirks for Gigabyte TRX40 Aorus Master onboard audio ... Browse Code »

    Gigabyte TRX40 Aorus Master is equipped with two USB-audio devices,
    a Realtek ALC1220-VB codec (USB ID 0414:a001) and an ESS SABRE9218 DAC
    (USB ID 0414:a000). The latter serves solely for the headphone output
    on the front panel while the former serves for the rest I/Os (mostly
    for the I/Os in the rear panel but also including the front mic).

    Both chips do work more or less with the unmodified USB-audio driver,
    but there are a few glitches. The ALC1220-VB returns an error for an
    inquiry to some jacks, as already seen on other TRX40-based mobos.
    However this machine has a slightly incompatible configuration, hence
    the existing mapping cannot be used as is.

    Meanwhile the ESS chip seems working without any quirk. But since
    both audio devices don't provide any specific names, both cards appear
    as "USB-Audio", and it's quite confusing for users.

    This patch is an attempt to overcome those issues:

    - The specific mapping table for ALC1220-VB is provided, reducing the
    non-working nodes and renaming the badly chosen controls.
    The connector map isn't needed here unlike other TRX40 quirks.

    - For both USB IDs (0414:a000 and 0414:a001), provide specific card
    name strings, so that user-space can identify more easily; and more
    importantly, UCM profile can be applied to each.

    This is another TRX40 based motherboard with ALC1220-VB USB-audio
    that requires a static mapping table.

    This motherboard also has a PCI device which advertises no codecs. The
    PCI ID is 1022:1487 and PCI SSID is 1022:d102. As this is using the AMD

  • fef66ae73   ALSA: usb-audio: Add connector notifier delegation ... Browse Code »

    It turned out that ALC1220-VB USB-audio device gives the interrupt
    event to some PCM terminals while those don't allow the connector
    state request but only the actual I/O terminals return the request.
    The recent commit 7dc3c5a0172e ("ALSA: usb-audio: Don't create jack
    controls for PCM terminals") excluded those phantom terminals, so
    those events are ignored, too.

    My first thought was that this could be easily deduced from the
    associated terminals, but some of them have even no associate terminal
    ID, hence it's not too trivial to figure out.

    Since the number of such terminals are small and limited, this patch
    implements another quirk table for the simple mapping of the
    connectors. It's not really scalable, but let's hope that there will
    be not many such funky devices in future.

    TRX40 mobos from MSI and others with ALC1220-VB USB-audio device need
    yet more quirks for the proper control names.

    This patch provides the mapping table for those boards, correcting the
    FU names for volume and mute controls as well as the terminal names
    for jack controls. It also improves build_connector_control() not to
    add the directional suffix blindly if the string is given from the
    mapping table.

    With this patch applied, the new UCM profiles will be effective.

    Some recent boards (supposedly with a new AMD platform) contain the
    USB audio class 2 device that is often tied with HD-audio. The device
    exposes an Input Gain Pad control (id=19, control=12) but this node
    doesn't behave correctly, returning an error for each inquiry of
    GET_MIN and GET_MAX that should have been mandatory.

    As a workaround, simply ignore this node by adding a usbmix_name_map
    table entry. The currently known devices are:
    * 0414:a002 - Gigabyte TRX40 Aorus Pro WiFi
    * 0b05:1916 - ASUS ROG Zenith II

    This is Dell usb dock audio workaround.
    It was fixed the master volume keep lower.

    [Some background: the patch essentially skips the controls of a couple
    of FU volumes. Although the firmware exposes the dB and the value
    information via the usb descriptor, changing the values (we set the
    min volume as default) screws up the device. Although this has been
    fixed in the newer firmware, the devices are shipped with the old
    firmware, thus we need the workaround in the driver side. -- tiwai]

  • 42e3121d9   ALSA: usb-audio: Add a more accurate volume quirk for AudioQuest DragonFly ... Browse Code »

    AudioQuest DragonFly DAC reports a volume control range of 0..50
    (0x0000..0x0032) which in USB Audio means a range of 0 .. 0.2dB, which
    is obviously incorrect and would cause software using the dB information
    in e.g. volume sliders to have a massive volume difference in 100..102%
    range.

    Commit 2d1cb7f658fb ("ALSA: usb-audio: add dB range mapping for some
    devices") added a dB range mapping for it with range 0..50 dB.

    However, the actual volume mapping seems to be neither linear volume nor
    linear dB scale, but instead quite close to the cubic mapping e.g.
    alsamixer uses, with a range of approx. -53...0 dB.

    Replace the previous quirk with a custom dB mapping based on some basic
    output measurements, using a 10-item range TLV (which will still fit in
    alsa-lib MAX_TLV_RANGE_SIZE).

    Tested on AudioQuest DragonFly HW v1.2. The quirk is only applied if the
    range is 0..50, so if this gets fixed/changed in later HW revisions it
    will no longer be applied.

    v2: incorporated Takashi Iwai's suggestion for the quirk application
    method
