  • 59ec4b57b   ALSA: hda - Fix headset mic detection problem for two dell machines ... Browse Code »

    One of the machines has ALC255 on it, another one has ALC298 on it.

    On the machine with the codec ALC298, it also has the speaker volume
    problem, so we add the fixup chained to ALC298_FIXUP_SPK_VOLUME rather
    than adding a group of pin definition in the pin quirk table, since
    the speak volume problem does not happen on other machines yet.

    On Acer Veriton machines, codec with subsystem-id 0x1b0a01b8 the port at
    0x15 is configured by default as an Internal Speaker (0x90170120).
    However, no physical is speaker installed on-board. This patch adds a quirk
    which disables the physical connection on this pin.

    We have a Dell AIO on which we can't adjust its speaker's volume.
    The problem is it is connected to a Audio Output node without Amp-out
    capability. To fix it, we change it to be connnected to a node with
    Amp-out capability.

  • 275353bb6   ALSA: echoaudio: purge contradictions between dimension matrix members and total number of members ... Browse Code »

    Currently, sound device drivers for PCI cards produced by Echo Audio
    support dimension parameter of element information. But the information
    has contradictions to the number of members of each element. I guess that
    this comes from the assumption that these sound cards are used only by
    'echomixer' in userspace. But ideally, they should be used with usual ALSA
    control applications.

    This commit removes the contradiction. As a result, 'Monitor Mixer Volume'
    and 'VMixer Volume' elements are shown in usual ALSA control applications
    such as 'amixer' and 'alsamixer' in series.

    'commpage_bak' is allocated with 'sizeof(struct echoaudio)' bytes.
    We then copy 'sizeof(struct comm_page)' bytes in it.
    On my system, smatch complains because one is 2960 and the other is 3072.

    This would result in memory corruption or a oops.

  • fabc16fe9   ALSA: hda - Turn off loopback mixing as default ... Browse Code »

    So far, we enabled the loopback mixing control as default, as this
    behavior made somewhat compatible with the earlier HD-audio drivers
    for Realtek & co. However, it's getting annoying as we've got more
    and more bug reports about the noise coming from the loopback route.
    Since the loopback mixing is used fairly rarely and often harmful
    (e.g. using PA), let's get rid of the default turn-on lines.

    Pull ACPI updates from Rafael Wysocki:
    "The new features here are ACPI 6.1 support (and some previously
    missing bits of ACPI 6.0 support) in ACPICA and two new drivers, a
    driver for the ACPI Generic Event Device (GED) feature introduced by
    ACPI 6.1 and the INT3406 thermal driver for display thermal
    management. Also the value returned by the _HRV (hardware revision)
    ACPI object will be exported to user space via sysfs now.

    In addition to that, ACPI on ARM64 will not depend on EXPERT any more.

    The rest is mostly fixes and cleanups and some code reorganization.

    Specifics:

    - In-kernel ACPICA code update to the upstream release 20160422
    adding support for ACPI 6.1 along with some previously missing bits
    of ACPI 6.0 support, making a fair amount of fixes and cleanups and
    reducing divergences between the upstream ACPICA and the in-kernel
    code (Bob Moore, Lv Zheng, Al Stone, Aleksey Makarov, Will Miles)

    - ACPI Generic Event Device (GED) support and a fix for it (Sinan
    Kaya, Paul Gortmaker)

    - INT3406 thermal driver for display thermal management and ACPI
    backlight support code reorganization related to it (Aaron Lu, Arnd
    Bergmann)

    - Support for exporting the value returned by the _HRV (hardware
    revision) ACPI object via sysfs (Betty Dall)

    - Removal of the EXPERT dependency for ACPI on ARM64 (Mark Brown)

    - Rework of the handling of ACPI _OSI mechanism allowing the
    _OSI("Darwin") support to be overridden from the kernel command
    line among other things (Lv Zheng, Chen Yu)

  • 639db5961   ALSA: au88x0: Fix zero clear of stream->resources ... Browse Code »

    There are a few calls of memset() to stream->resources, but they all
    are called in a wrong size, sizeof(unsigned char) * VORTEX_RESOURCE_LAST,
    while this field is a u32 array. This may leave the memories not
    zero-cleared.

    Fix it by replacing them with a simpler sizeof(stream->resources)
    instead.

  • 396692254   ALSA: hda - Fix regression on ATI HDMI audio ... Browse Code »

    The HDMI/DP audio output on ATI/AMD chips got broken due to the recent
    restructuring of chmap. Fortunately, Daniel Exner could bisect, and
    pointed the culprit commit [739ffee97ed5: ALSA: hda - Add hdmi chmap
    verb programming ops to chmap object].

    This commit moved some ops from hdmi_ops to chmap_ops, and reassigned
    the ops in the embedded chmap object in hdmi_spec instead.
    Unfortunately, the reassignment of these ops in patch_atihdmi() were
    moved into an if block that is performed only for old chips. Thus, on
    newer chips, the generic ops is still used, which doesn't work for
    such ATI/AMD chips.

    This patch addresses the regression, simply by moving the assignment
    of chmap ops to the right place.
