ASoC: doc: Fix undefined SND_SOC_DAPM_NOPM argument

2024-02-05T20:14:26+00:00

[ 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: emu10k1: add separate documentation for E-MU cards

ALSA: emu10k1: more documentation updates

2023-08-26T07:25:08+00:00

- Clarify the data flows. For SB Live! I fixed only the most obvious point ("from" vs. "for"). - Mention 7.1 side channels on Audigy. - Be unspecific about the output DACs on Audigy, as lots of variants actually exist (see emu_chip_details table).

ALSA: emu10k1: de-duplicate audigy-mixer.rst vs. sb-live-mixer.rst

2023-08-26T07:24:59+00:00

Let the MANUALS/PATENTS section of the former simply refer to the latter - there is no point in duplicating this information with little value to end users.

The USB MIDI 2.0 gadget driver is now supported for 6.6 kernel, and here we show a brief instruction how to enable and use it. Link: https://lore.kernel.org/r/20230824075108.29958-5-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: doc: Update description for the new PCM copy ops

2023-08-18T10:19:19+00:00

Update the documentation about the PCM copy callbacks. The update was kept minimalistic, just correcting the use of copy_user ops with the single copy ops, and drop/update the text mentioning the copy_kernel.

ALSA: compress: allow setting codec params after next track

2023-06-21T05:28:31+00:00

For gapless playback it is possible that each track can have different codec profile with same decoder, for example we have WMA album, we may have different tracks as WMA v9, WMA v10 and so on Or if DSP's like QDSP have abililty to switch decoders on single stream for each track, then this call could be used to set new codec parameters. Existing code does not allow to change this profile while doing gapless playback. Reuse existing SNDRV_COMPRESS_SET_PARAMS to set this new track params along some additional checks to enforce proper state machine. With this new changes now the user can call SNDRV_COMPRESS_SET_PARAMS anytime after setting next track and additional check in write should also ensure that params are set before writing new data.

Merge branch 'topic/midi20' into for-next

2023-06-13T05:37:59+00:00

As the updated MIDI 2.0 spec has been published freshly, this is a catch up to add the support for new specs, especially UMP v1.1 features, on Linux kernel. The new UMP v1.1 introduced the concept of Function Blocks (FB), which is a kind of superset of USB MIDI 2.0 Group Terminal Blocks (GTB). The patch set adds the support for FB as the primary information source while keeping the parse of GTB as fallback. Also UMP v1.1 supports the groupless messages, the protocol switch, static FBs, and other new fundamental features, and those are supported as well.
