[alsa-devel] [PATCH] alsactl: avoid needless wakeups in monitor loop.
by Zev Weiss 14 Apr '20

14 Apr '20

The timeout wasn't really being used for anything; disabling it should reduce idle energy consumption slightly.

[alsa-devel] [PATCH] alsactl: don't exit on EINTR from epoll_wait().
by Zev Weiss 14 Apr '20

14 Apr '20

Previously, things like attaching strace to a running 'alsactl monitor' process would cause it to exit.

[PATCH] quirk for Pioneer DJ DJM-250MK2 usb sound card
by František Kučera 03 Apr '20

03 Apr '20

Hello, I have created a quirk that adds support for the Pioneer DJ DJM-250MK2 mixer (acts like a USB sound card, but Vendor Specific Class). Output (from computer to card) is working: 8 channels, 48 000 Hz, S24_3LE. Input is not working. I tried, but I was unable to make it working even under an officially supported OS with Pioneer drivers - Audacity or Mixxx see the channels, but there is no signal. It probably works only with Pioneer proprietary application. But I hope that even mere output support will be useful for someone. (it is usable for playback, just not for DVS) Franta Signed-off-by: František Kučera <franta-linux(a)frantovo.cz> --- sound/usb/quirks-table.h | 42 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) diff --git a/sound/usb/quirks-table.h b/sound/usb/quirks-table.h index d187aa6d50db..dcaf9eed9a41 100644 --- a/sound/usb/quirks-table.h +++ b/sound/usb/quirks-table.h @@ -3592,5 +3592,47 @@ AU0828_DEVICE(0x2040, 0x7270, "Hauppauge", "HVR-950Q"), } } }, +{ + /* + * Pioneer DJ DJM-250MK2 + * PCM is 8 channels out @ 48 fixed (endpoints 0x01). + * The output from computer to the mixer is usable. + * + * The input (phono or line to computer) is not working. + * It should be at endpoint 0x82 and probably also 8 channels, + * but it seems that it works only with Pioneer proprietary software. + * Even on officially supported OS, the Audacity was unable to record + * and Mixxx to recognize the control vinyls. + */ + USB_DEVICE_VENDOR_SPEC(0x2b73, 0x0017), + .driver_info = (unsigned long) &(const struct snd_usb_audio_quirk) { + .ifnum = QUIRK_ANY_INTERFACE, + .type = QUIRK_COMPOSITE, + .data = (const struct snd_usb_audio_quirk[]) { + { + .ifnum = 0, + .type = QUIRK_AUDIO_FIXED_ENDPOINT, + .data = &(const struct audioformat) { + .formats = SNDRV_PCM_FMTBIT_S24_3LE, + .channels = 8, // outputs + .iface = 0, + .altsetting = 1, + .altset_idx = 1, + .endpoint = 0x01, + .ep_attr = USB_ENDPOINT_XFER_ISOC| + USB_ENDPOINT_SYNC_ASYNC, + .rates = SNDRV_PCM_RATE_48000, + .rate_min = 48000, + .rate_max = 48000, + .nr_rates = 1, + .rate_table = (unsigned int[]) { 48000 } + } + }, + { + .ifnum = -1 + } + } + } +}, #undef USB_DEVICE_VENDOR_SPEC

[alsa-devel] [PATCH v3 0/7] ASoC: soc-pcm cleanup step2
by Kuninori Morimoto 31 Mar '20

31 Mar '20

Hi Mark These are v3 of soc-pcm cleanup. Original [5/7] [6/7] patch call open / start function for all DAI / component. And, it calls close / stop function for all if some of them got error. But in such case, error occured DAI / component don't need to call close / stop. This issue can be solved if it had flag, and my local tree has such patch. But it was planed to post to ML a little later. This time, I merged original patch and this new flag patch on [5/7] [6/7]. These mention that "it is prepare for soc-pcm-open() cleanup". But it will be happen later. These are based on v5.6-rc1 Kuninori Morimoto (8): 1) ASoC: soc-pcm: add snd_soc_runtime_action() 2) ASoC: soc-pcm: adjustment for DAI member 0 reset 3) ASoC: soc-pcm: add for_each_dapm_widgets() macro 4) ASoC: soc-pcm: don't use bit-OR'ed error 5) ASoC: soc-pcm: call snd_soc_dai_startup()/shutdown() once 6) ASoC: soc-pcm: call snd_soc_component_open/close() once 7) ASoC: soc-pcm: move soc_pcm_close() next to soc_pcm_open() 8) ASoC: soc-pcm: tidyup soc_pcm_open() order include/sound/soc-component.h | 7 +- include/sound/soc-dai.h | 5 +- include/sound/soc-dapm.h | 5 + sound/soc/soc-component.c | 35 ++++-- sound/soc/soc-dai.c | 11 +- sound/soc/soc-dapm.c | 8 +- sound/soc/soc-pcm.c | 246 +++++++++++++++++++----------------------- 7 files changed, 161 insertions(+), 156 deletions(-) -- 2.7.4

[alsa-devel] [PATCH 0/3] ALSA: bebob: misc improvements for starting/stopping packet streaming
by Takashi Sakamoto 27 Mar '20

27 Mar '20

Hi, This patchset improves model-specific issues in a point of protocol version supported by the model. The changes are relevant to packet streaming, thus it can brings some regressions. For testers, I prepare for a remote branch to backport the latest codes to Linux v4.17 or later. I'm happy to receive any report. https://github.com/takaswie/snd-firewire-improve/tree/topic/bebob-connectio… Takashi Sakamoto (3): ALSA: bebob: expand sleep just after breaking connections for protocol version 1 ALSA: bebob: expand delay of start for IR context just for version 3 firmware ALSA: bebob: link the order of establishing connections and Syt-match clock mode sound/firewire/bebob/bebob_stream.c | 76 ++++++++++++++--------------- 1 file changed, 38 insertions(+), 38 deletions(-) -- 2.20.1

[PATCH 0/8] soundwire: remove platform devices, add SOF interfaces
by Pierre-Louis Bossart 23 Mar '20

23 Mar '20

The first two patches were already reviewed by Greg KH in an earlier RFC. Since I only cleaned-up the error handling flow and removed an unnecessary wrapper, I took the liberty of adding Greg's Reviewed-by tag for these two patches. The rest of the patches implement the interfaces required for the SOF driver (interrupts handled with a single handler, PCI wakes and sharing of _ADR information to select a machine driver). When this patchset is merged, a tag will need to be shared with Mark Brown so that we can provide the SOF patches to the ASoC tree and enable SoundWire in builds for Intel platforms.

[alsa-devel] [PATCH] ASoC: sgtl5000: Revert "ASoC: sgtl5000: Fix of unmute outputs on probe"
by Alison Wang 21 Mar '20

21 Mar '20

This reverts commit 631bc8f0134ae9620d86a96b8c5f9445d91a2dca. In commit 631bc8f0134a, snd_soc_component_update_bits is used instead of snd_soc_component_write. Although EN_HP_ZCD and EN_ADC_ZCD are enabled in ANA_CTRL register, MUTE_LO, MUTE_HP and MUTE_ADC bits are remained as the default value. It causes LO, HP and ADC are all muted after driver probe. The patch is to revert this commit, snd_soc_component_write is still used and MUTE_LO, MUTE_HP and MUTE_ADC are set as zero (unmuted).

[alsa-devel] [PATCH v3 0/9] x86: Easy way of detecting MS Surface 3
by Andy Shevchenko 16 Mar '20

16 Mar '20

While working on RTC regression, I noticed that we are using the same DMI check over and over in the drivers for MS Surface 3 platform. This series dedicated for making it easier in the same way how it's done for Apple machines. Changelog v3: - fixed typo in patch 5 (Jonathan) - returned back to if {} else {} condition in ASoC driver (Mark) - added Mark's Ack tag Changelog v2: - removed RTC patches for now (the fix will be independent to this series) - added couple more clean ups to arch/x86/kernel/quirks.c - redone DMI quirk to use driver_data instead of callback - simplified check in soc-acpi-intel-cht-match.c to be oneliner - added a new patch to cover rt5645 codec driver Cc: Cezary Rojewski <cezary.rojewski(a)intel.com> Cc: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> Cc: Liam Girdwood <liam.r.girdwood(a)linux.intel.com> Cc: Jie Yang <yang.jie(a)linux.intel.com> Cc: Mark Brown <broonie(a)kernel.org> Cc: alsa-devel(a)alsa-project.org Andy Shevchenko (9): x86/platform: Rename x86/apple.h -> x86/machine.h x86/quirks: Add missed include to satisfy static checker x86/quirks: Introduce hpet_dev_print_force_hpet_address() helper x86/quirks: Join string literals back x86/quirks: Convert DMI matching to use a table x86/quirks: Add a DMI quirk for Microsoft Surface 3 platform/x86: surface3_wmi: Switch DMI table match to a test of variable ASoC: rt5645: Switch DMI table match to a test of variable ASoC: Intel: Switch DMI table match to a test of variable arch/x86/kernel/quirks.c | 91 +++++++++++++------ drivers/platform/x86/surface3-wmi.c | 16 +--- include/linux/platform_data/x86/apple.h | 14 +-- include/linux/platform_data/x86/machine.h | 20 ++++ sound/soc/codecs/rt5645.c | 14 ++- .../intel/common/soc-acpi-intel-cht-match.c | 28 +----- 6 files changed, 93 insertions(+), 90 deletions(-) create mode 100644 include/linux/platform_data/x86/machine.h -- 2.24.1
