[PATCH] ALSA: usb-audio: Pass JOINT_DUPLEX info flag for implicit fb streams
by Takashi Iwai 07 Oct '21

07 Oct '21

When a stream is in the implicit feedback mode, it's more or less tied with a capture stream. Passing SNDRV_PCM_INFO_JOINT_DUPLEX may help for user-space to understand the situation.

[PATCH] ASoC: soc-acpi: add alternative id field for machine driver matching
by Brent Lu 06 Oct '21

06 Oct '21

Current design to support second headphone driver in the same machine driver is to duplicate the entries in snd_soc_acpi_mach array and board configs in machine driver. We can avoid this by adding an id_alt field in snd_soc_acpi_mach structure to specify alternative ACPI HIDs for machine driver enumeration and leave the codec type detection to machine driver if necessary.

[PATCH] ALSA: hda/realtek: Add quirk for TongFang PHxTxX1
by Werner Sembach 06 Oct '21

06 Oct '21

This applies a SND_PCI_QUIRK(...) to the TongFang PHxTxX1 barebone. This fixes the issue of the internal Microphone not working after booting another OS. When booting a certain another OS this barebone keeps some coeff settings even after a cold shutdown. These coeffs prevent the microphone detection from working in Linux, making the Laptop think that there is always an external microphone plugged-in and therefore preventing the use of the internal one. The relevant indexes and values where gathered by naively diff-ing and reading a working and a non-working coeff dump.
