ALSA: ice1724: Use linear scale for AK4396 volume control.

2012-10-02T16:47:23+00:00

commit 3737e2be505d872bf2b3c1cd4151b2d2b413d7b5 upstream.

The AK4396 DAC has a linear-scale attentuator, but
sound/pci/ice1712/prodigy_hifi.c used a log scale instead, which is
not quite right.  This patch restores the correct scale, borrowing
from the ak4396 code in sound/pci/oxygen/oxygen.c.

ASoC: wm9712: Fix microphone source selection

2012-09-14T17:00:37+00:00

commit ccf795847a38235ee4a56a24129ce75147d6ba8f upstream.

Currently the microphone input source is not selectable as while there is
a DAPM widget it's not connected to anything so it won't be properly
instantiated. Add something more correct for the input structure to get
things going, even though it's not hooked into the rest of the routing
map and so won't actually achieve anything except allowing the relevant
register bits to be written.

ASoC: wm8994: Ensure there are enough BCLKs for four channels

2012-08-09T15:27:53+00:00

commit b8edf3e5522735c8ce78b81845f7a1a2d4a08626 upstream.

Otherwise if someone tries to use all four channels on AIF1 with the
device in master mode we won't be able to clock out all the data.

ALSA: mpu401: Fix missing initialization of irq field

2012-08-09T15:27:53+00:00

commit bc733d495267a23ef8660220d696c6e549ce30b3 upstream.

The irq field of struct snd_mpu401 is supposed to be initialized to -1.
Since it's set to zero as of now, a probing error before the irq
installation results in a kernel warning "Trying to free already-free
IRQ 0".

ALSA: snd-usb: fix clock source validity index

2012-08-09T15:27:53+00:00

commit aff252a848ce21b431ba822de3dab9c4c94571cb upstream.

uac_clock_source_is_valid() uses the control selector value to access
the bmControls bitmap of the clock source unit. This is wrong, as
control selector values start from 1, while the bitmap uses all
available bits.

In other words, "Clock Validity Control" is stored in D3..2, not D5..4
of the clock selector unit's bmControls.

ALSA: hda - Add support for Realtek ALC282

2012-08-09T15:27:35+00:00

commit 4e01ec636e64707d202a1ca21a47bbc6d53085b7 upstream.

This codec has a separate dmic path (separate dmic only ADC),
and thus it looks mostly like ALC275.

ASoC: tlv320aic3x: Fix codec pll configure bug

2012-07-16T15:47:39+00:00

commit c9fe573a6584034670c1a55ee8162d623519cbbf upstream.

In sound/soc/codecs/tlv320aic3x.c

        data = snd_soc_read(codec, AIC3X_PLL_PROGA_REG);
        snd_soc_write(codec, AIC3X_PLL_PROGA_REG,
                      data | (pll_p << PLLP_SHIFT));

In the above code, pll-p value is OR'ed with previous value without
clearing it. Bug is not seen if pll-p value doesn't change across
Sampling frequency.

However on some platforms (like AM335x EVM-SK), pll-p may have different
values across different sampling frequencies. In such case, above code
configures the pll with a wrong value.
Because of this bug, when a audio stream is played with pll value
different from previous stream, audio is heard as differently(like its
stretched).

ALSA: hda - Add Realtek ALC280 codec support

2012-07-16T15:47:35+00:00

commit befae82e2906cb7155020876a531b0b8c6c8d8c8 upstream.

This chip looks very similar to ALC269 and ALC27* variants. The bug reporter
has verified that sound was working after this patch had been applied.
