[alsa-devel] [PATCH] ASoC: davinci-mcasp: Add clocking option
by Stefan Müller-Klieser 01 Aug '16

01 Aug '16

The AHCLKX clock output of the McASP can be used as audio MCLK, even if the McASP runs in slave mode. Add a DT binding to make this option available in a simple-card setup.

[alsa-devel] [PATCH] ALSA: hda - On-board speaker fixup on ACER Veriton
by Shrirang Bagul 01 Aug '16

01 Aug '16

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.

[alsa-devel] [PATCH] ALSA: hda/realtek - Can't adjust speaker's volume on a Dell AIO
by Hui Wang 01 Aug '16

01 Aug '16

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.
