[alsa-devel] tegra30 tdm audio support
by Ben Dooks 07 Oct '19

07 Oct '19

This adds support for tegra30 tdm audio and fixes a bug in the fifo handling on rx when non-32 bit aligned data is used. v2: - moved edge-control and data-offset to the set_fmt callbacks - fixed dev_dbg in set_tdm callback - fixed dev_dbg message contents in set_tdm callback - changed fsync width to be permanently 1 clock v3: - cleanup fsync patch - fix rebase issue with tdm patch

[alsa-devel] [PATCH] ALSA: hdac: clear link output stream mapping
by Pierre-Louis Bossart 07 Oct '19

07 Oct '19

From: Rander Wang <rander.wang(a)linux.intel.com> Fix potential DMA hang upon starting playback on devices in HDA mode on Intel platforms (Gemini Lake/Whiskey Lake/Comet Lake/Ice Lake). It doesn't affect platforms before Gemini Lake or any Intel device in non-HDA mode. The reset value for the LOSDIV register is all output streams valid. Clear this register to invalidate non-existent streams when the bus is powered up.

[alsa-devel] [PATCH] ALSA: hda/realtek: Reduce the Headphone static noise on XPS 9350/9360
by Kai-Heng Feng 07 Oct '19

07 Oct '19

Headphone on XPS 9350/9360 produces a background white noise. The The noise level somehow correlates with "Headphone Mic Boost", when it sets to 1 the noise disappears. However, doing this has a side effect, which also decreases the overall headphone volume so I didn't send the patch upstream. The noise was bearable back then, but after commit 717f43d81afc ("ALSA: hda/realtek - Update headset mode for ALC256") the noise exacerbates to a point it starts hurting ears. So let's use the workaround to set "Headphone Mic Boost" to 1 and lock it so it's not touchable by userspace.

[alsa-devel] [PATCH v2] ALSA: hda: add Intel DSP configuration / probe code
by Jaroslav Kysela 06 Oct '19

06 Oct '19

For distributions, we need one place where we can decide which driver will be activated for the auto-configation of the Intel's HDA hardware with DSP. Actually, we cover three drivers: * Legacy HDA * Intel SST * Intel Sound Open Firmware (SOF) All those drivers registers similar PCI IDs, so the first driver probed from the PCI stack can win. But... it is not guaranteed that the correct driver wins. This commit changes Intel's NHLT ACPI module to a common DSP probe module for the Intel's hardware. All above sound drivers calls this code. The user can force another behaviour using the module parameter 'dsp_driver' located in the 'snd-intel-dspcfg' module. This change allows to add specific dmi checks for the specific systems like proposed in the pull request: https://github.com/thesofproject/linux/pull/927 Tested on Lenovo Carbon X1 7th gen.

[alsa-devel] alsa compliance test: H340 (USB audio) playback / capture rate asymmetry bug?
by Hin-Tak Leung 05 Oct '19

05 Oct '19

I am using Takashi Iwai's tree grafted onto mainline as DKMS ( as in https://github.com/HinTak/sound-usb-dkms ). Running the alsa compliance test commit f6167eb77d038b5b7a0d39645e7f2ae7fee6fdc0 (origin/stabilize-12464.B, origin/release-R78-12499.B) Capture all passed, but play back failed a couple, regarding the sample rate. It is a small head set with stereo head phone and a mic. ID 046d:0a38 Logitech, Inc. Headset H340 The question is, for such a cheap headset, why would the playback rate and the capture rate to be different? For many applications/ usages, with a device that's most capture and playback capable, we would like the rates to agree - both pass, or both fail in the same direction? Is this a hardware or software issue? Or, somebody suggested, I haven't looked, issue with the alsa compliance test itself, possibly regarding frame counts of usb devices? detail below. 5 passed, 0 failed Device Information Name: hw:CARD=H340 Stream: CAPTURE Format: ['S16_LE'] Channels range: [2, 2] Rate: [44100] Period_size range: [45, 131072] Buffer_size range: [90, 262144] Test Params Set channels 2: pass Set format S16_LE: pass Set rate 44100: pass Test Rates Set rate 44100: pass Test All Pairs Set channels 2, format S16_LE, rate 44100: pass 3 passed, 2 failed Device Information Name: hw:CARD=H340 Stream: PLAYBACK Format: ['S16_LE'] Channels range: [2, 2] Rate: [44100] Period_size range: [45, 131072] Buffer_size range: [90, 262144] Test Params Set channels 2: pass Set format S16_LE: pass Set rate 44100: pass Test Rates Set rate 44100: fail - Expected rate is 44100.000000, measure 44092.918362, difference 7.081638 > threshold 4.410000 Test All Pairs Set channels 2, format S16_LE, rate 44100: fail - Expected rate is 44100.000000, measure 44093.049192, difference 6.950808 > threshold 4.410000

[alsa-devel] [RFC PATCH 0/2] Alter the trigger order for FE/BE DAI's based on command
by Ranjani Sridharan 05 Oct '19

05 Oct '19

Currently, the trigger orders SND_SOC_DPCM_TRIGGER_PRE/POST determine the order in which FE DAI and BE DAI are triggered. In the case of SND_SOC_DPCM_TRIGGER_PRE, the FE DAI is triggered before the BE DAI and in the case of SND_SOC_DPCM_TRIGGER_POST, the BE DAI is triggered before the FE DAI. And this order remains the same irrespective of the trigger command. In the case of the SOF driver, during playback, the FW expects the BE DAI to be triggered before the FE DAI during the START trigger. The BE DAI trigger handles the starting of Link DMA and so it must be started before the FE DAI is started to prevent xruns during pause/release. This can be addressed by setting the trigger order for the FE dai link to SND_SOC_DPCM_TRIGGER_POST. But during the STOP trigger, the FW expects the FE DAI to be triggered before the BE DAI. Retaining the same order during the START and STOP commands, results in FW error as the DAI component in the FW is still active. The issue can be fixed by mirroring the trigger order of FE and BE DAI's during the START and STOP trigger. So, with the trigger order set to SND_SOC_DPCM_TRIGGER_PRE, the FE DAI will be trigger first during SNDRV_PCM_TRIGGER_START/STOP/RESUME and the BE DAI will be triggered first during the STOP/SUSPEND/PAUSE commands. Conversely, with the trigger order set to SND_SOC_DPCM_TRIGGER_POST, the BE DAI will be triggered first during the SNDRV_PCM_TRIGGER_START/STOP/RESUME commands and the FE DAI will be triggered first during the SNDRV_PCM_TRIGGER_STOP/SUSPEND/PAUSE commands. My first thought was to use a BESPOKE trigger for the SOF driver but looking more into the implementation of the bespoke trigger in soc_pcm_bespoke_trigger() didnt indicate it had much to do with the ordering of the FE/BE DAI's but rather just use the bespoke trigger callbacks in the DAI driver. More details on the SOF issue can be found in: Github Issue: https://github.com/thesofproject/linux/issues/1160 Ranjani Sridharan (2): ASoC: pcm: update FE/BE trigger order based on the command ASoC: SOF: topology: set trigger order for FE DAI link sound/soc/soc-pcm.c | 99 +++++++++++++++++++++++++++++----------- sound/soc/sof/topology.c | 4 ++ 2 files changed, 76 insertions(+), 27 deletions(-) -- 2.17.1

[alsa-devel] [PATCH] ASoC: tas2770: Fix snd_soc_update_bits error handling
by Dan Murphy 04 Oct '19

04 Oct '19

According the documentation for snd_soc_update_bits the API will return a 1 if the update was successful with a value change, a 0 if the update was successful with no value change or a negative if the command just failed. So the value of return in the driver needs to be checked for being less then 0 or the caller may indicate failure when the value actually changed.
