[alsa-devel] [PATCH] ALSA: hda/realtek - add two more pin configuration sets to quirk table
by Hui Wang 17 Apr '19
by Hui Wang 17 Apr '19
17 Apr '19
We have two Dell laptops which have the codec 10ec0236 and 10ec0256
respectively, the headset mic on them can't work, need to apply the
quirk of ALC255_FIXUP_DELL1_MIC_NO_PRESENCE. So adding their pin
configurations in the pin quirk table.

Hi Takashi,
Our AE told me, that EAPD turn on timing which need to set pin out first.
It's the safe application. It could avoid pop noise via speaker.
So, could I do the modify as below patch.
BR,

[alsa-devel] [PATCH 1/2] ALSA: emu10k1: Drop superfluous id-uniquification behavior
by Takashi Iwai 16 Apr '19
by Takashi Iwai 16 Apr '19
16 Apr '19
The emu10k1 driver tries to create a unique id string by itself when
it's copied from the card list, but it's rather superfluous, as the
same thing will be done in ALSA core side at the card registration.
Let's drop the code. This allows us removing snd_cards export.

[alsa-devel] [PATCH] ASoC: rockchip: Select DMA_PL330 by RK3399 audio
by Alyssa Rosenzweig 16 Apr '19
by Alyssa Rosenzweig 16 Apr '19
16 Apr '19
Without the appropriate DMA controller selected, the RK3399 audio
drivers compile but fail immediately. Accordingly, selecting the RK3399
audio without the corresponding PL330 controller is an invalid
configuration. Prevent errors (otherwise forcing the driver to unload at
runtime) by an appropriate `select` directive in the Kconfig.

Hi,
syzkaller hilariously spotted some possible races via its usb
fuzzing. I thought it were specific to USB-audio stuff, but no it's
in the ALSA core side. So below is the resultant fixes.
