[alsa-devel] [PATCH] ASoC: AMD: constify regulator_desc structure
by Julia Lawall 05 Nov '18

05 Nov '18

The regulator_desc structure can be const as it is only passed as the second argument of devm_regulator_register and the corresponding parameter is declared as const. Done with the help of Coccinelle.

[alsa-devel] [PATCH] ASoC: omap-mcbsp: On OMAP1 and OMAP2420 only 16bit format is supported
by Peter Ujfalusi 05 Nov '18

05 Nov '18

For samples sizes of 20/24/32 bit the DRR2/DXR2 registers must be used to receive or transmit the most significant part of the 32bit sample. We can not trick the system by using the DRR2/DXR2 register offset and use 32bit element size since these (and other McBSP) registers are 16bit ones. We would need support for port_window in cyclic mode from the sDMA driver, but it is not straight forward as we would need to have the sDMA frame to cover the 32bit (DRR2+DRR1/DXR2+DXR1), but the frames must cover the ALSA period to be able to receive periodic interrupts. Since the 32bit samples are not working (DMA timeout), just remove it in case we have McBSP with reg_size of 2.

[alsa-devel] [PATCH] ASoC: intel: cht_bsw_max98090_ti: Add quirk for boards using pmc_plt_clk_0
by Hans de Goede 05 Nov '18

05 Nov '18

Some boards such as the Swanky model Chromebooks use pmc_plt_clk_0 for the mclk instead of pmc_plt_clk_3. This commit adds a DMI based quirk for this. This fixing audio no longer working on these devices after commit 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL") that commit fixes us unnecessary keeping unused clocks on, but in case of the Swanky that was breaking audio support since we were not using the right clock in the cht_bsw_max98090_ti machine driver.

Hi, I have the Rolands TD-30 edrum module that includes a USB sound card in it. The card lists but no capture or recording devices work, although they are listed. I am new to audio device drivers and for that reason need some guidance to contribute to such driver. A full log can be found at: www.alsa-project.org/db/?f=e1a28cbd7e9f1201d3b0cbe44d8ec1908272a1d4 Looking forward to ear from you. Best regards, Cupertino Miranda
