[alsa-devel] [PATCH 1/1] intel hda: add model dell-m6 quirk for the Dell Studio 15 (1537)
by Andy Whitcroft 02 Dec '08

02 Dec '08

Sort out the headphone connections for the Dell Studio 15 (1537), by default there is no sound from this socket. This seems to have the same wiring as a dell-m6. Automatically detect and select that model.

[alsa-devel] [PATCH] ASoC: TWL4030: Add capture source selection and mic gain control
by Grazvydas Ignotas 02 Dec '08

02 Dec '08

The TWL4030 codec device has two ADCs. Both of them can have several inputs routed to them, but TRM says that only one source can be selected for every ADC, even though every source has a dedicated bit in the registers. This patch adds controls for capture source controls. When a microphone is selected, handlers automatically enable bias power (disable when deselected). The patch also adds microphone gain control. Microphone and line input recording tested on OMAP3 pandora board.

[alsa-devel] ASoC: TWL4030 codec: Multiple DAC nameing
by Peter Ujfalusi 02 Dec '08

02 Dec '08

Hello, Now I have some working prototype for the TWL4030 codec DAPM playback routing. But before I send the patches I want to clear out something: Since the TWL has four DACs and I want to map all of them, what would be the correct SND_SOC_DAPM_DAC naming for them? At the moment I have these: /* DACs */ SND_SOC_DAPM_DAC("DACR1", "Right Front Playback", TWL4030_REG_AVDAC_CTL, 0, 0), SND_SOC_DAPM_DAC("DACL1", "Left Front Playback", TWL4030_REG_AVDAC_CTL, 1, 0), SND_SOC_DAPM_DAC("DACR2", "Right Rear Playback", TWL4030_REG_AVDAC_CTL, 2, 0), SND_SOC_DAPM_DAC("DACL2", "Left Rear Playback", TWL4030_REG_AVDAC_CTL, 3, 0), Are these are OK, or should I just use "Right Playback" for both DACR1 and DACR2? Btw: the 'dynamic' routing and switching now works (no user visible power control for the DACs and APGAs) in a way, that if the output is configured to take the audio from one of the DAC, than the corresponding chain (APGA, DAC) will be powered on only. Thanks, Péter

[alsa-devel] (SoC) Does i.MX27's SSI work as I2S clock master?
by ngc＠drvlabo.jp 01 Dec '08

01 Dec '08

Hello, lists. Now I'm porting WM8728 driver with i.MX27ADS, based on Freescale's BSP kernel(2.6.22) and refering to ALSA SoC git repository. I'm connecting the WM8728 to the SSI2 controller via SSI-3 signal set. Then, my ADS board has altered: i.MX27 WM8728 --------------------- SSI3_CLK BCLKIN SSI3_FS LRCIN SSI3_TXDAT DIN TOUT/SSI2_MCLK MCLK Of course, I added some codes to configure GPIO pins as appropriate into board specific sources. Then, I'm trying to play sounds via WM8728 and have not hear any sounds yet. I checked SSI-3 signal set with an oscilloscope, no clock signal appears on SSI3_CLK. I tried the various SSI setting, I2S normal, I2S master, asychronous/synchronous, normal mode/network mode, ... But, I can't see clock signal, yet. I want to know an example setting to act i.MX' SSI as I2S clock master. Regards, -------------- NOGUCHI Hiroshi ngc(a)drvlabo.jp
