ASoC: doc: Fix undefined SND_SOC_DAPM_NOPM argument

2024-02-23T07:12:48Z

[ Upstream commit 67c7666fe808c3a7af3cc6f9d0a3dd3acfd26115 ] The virtual widget example makes use of an undefined SND_SOC_DAPM_NOPM argument passed to SND_SOC_DAPM_MIXER(). Replace with the correct SND_SOC_NOPM definition.

ALSA: hda/realtek - Remove now-unnecessary XPS 13 headphone noise fixups

2020-04-17T08:48:45Z

commit f36938aa7440f46a0a365f1cfde5f5985af2bef3 upstream. patch_realtek.c has historically failed to properly configure the PC Beep Hidden Register for the ALC256 codec (among others). Depending on your kernel version, symptoms of this misconfiguration can range from chassis noise, picked up by a poorly-shielded PCBEEP trace, getting amplified and played on your internal speaker and/or headphones to loud feedback, which responds to the "Headphone Mic Boost" ALSA control, getting played through your headphones. For details of the problem, see the patch in this series titled "ALSA: hda/realtek - Set principled PC Beep configuration for ALC256", which fixes the configuration. These symptoms have been most noticed on the Dell XPS 13 9350 and 9360, popular laptops that use the ALC256. As a result, several model-specific fixups have been introduced to try and fix the problem, the most egregious of which locks the "Headphone Mic Boost" control as a hack to minimize noise from a feedback loop that shouldn't have been there in the first place. Now that the underlying issue has been fixed, remove all these fixups. Remaining fixups needed by the XPS 13 are all picked up by existing pin quirks. This change should, for the XPS 13 9350/9360 - Significantly increase volume and audio quality on headphones - Eliminate headphone popping on suspend/resume - Allow "Headphone Mic Boost" to be set again, making the headphone jack fully usable as a microphone jack too.

ALSA: doc: Document PC Beep Hidden Register on Realtek ALC256

2020-04-17T08:48:44Z

commit f128090491c3f5aacef91a863f8c52abf869c436 upstream. This codec (among others) has a hidden set of audio routes, apparently designed to allow PC Beep output without a mixer widget on the output path, which are controlled by an undocumented Realtek vendor register. The default configuration of these routes means that certain inputs aren't accessible, necessitating driver control of the register. However, Realtek has provided no documentation of the register, instead opting to fix issues by providing magic numbers, most of which have been at least somewhat erroneous. These magic numbers then get copied by others into model-specific fixups, leading to a fragmented and buggy set of configurations. To get out of this situation, I've reverse engineered the register by flipping bits and observing how the codec's behavior changes. This commit documents my findings. It does not change any code.

Merge tag 'asoc-v4.19' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2018-08-13T10:12:31Z

ASoC: Updates for v4.19 A fairly big update, including quite a bit of core activity this time around (which is good to see) along with a fairly large set of new drivers. - A new snd_pcm_stop_xrun() helper which is now used in several drivers. - Support for providing name prefixes to generic component nodes. - Quite a few fixes for DPCM as it gains a bit wider use and more robust testing. - Generalization of the DIO2125 support to a simple amplifier driver. - Accessory detection support for the audio graph card. - DT support for PXA AC'97 devices. - Quirks for a number of new x86 systems. - Support for AM Logic Meson, Everest ES7154, Intel systems with RT5682, Qualcomm QDSP6 and WCD9335, Realtek RT5682 and TI TAS5707.

ASoC: doc: Replace open code with params_set_format()

2018-07-26T16:09:05Z

The example code in dpcm.rst contains an open code calling snd_mask_set(), and this can be better represented with params_set_format() instead. This automatically fixes the sparse warning about snd_pcm_format_t handling, too. Signed-off-by: Takashi Iwai Signed-off-by: Mark Brown
