[alsa-devel] ASoC: fsl_sai: Has anybody attempted to run the i.MX6UL in TDM mode with channels > 2?
by Caleb Crome 19 Jan '17

19 Jan '17

Hi all, Now that the MX6 fsl_ssi seems to be getting stable for TDM with channels > 2 (thanks all!), the MX6 UL and MX7 have only the SAI port. Does anybody have experience with running the SAI with more than 2 channels? Any thoughts or comments would be welcome! Thanks, -Caleb

[alsa-devel] Alsamixer: missing Speakers entry in analog output choice (chipset AV200)
by Germano Massullo 08 Jan '17

08 Jan '17

I have a Asus Xonar Essence ST soundboard (Chip: AV200) on Fedora 23 kernel 4.4.5-300.fc23.x86_64 The audiocard has 3 different outputs - Speakers - Headphones - FP Headphones that have mutual exclusion, so that when you are using one of them, you cannot use the others. Sometimes the Speakers output disappears from alsamixer. By restarting the computer, the system gets back to its normal behaviour. I attach 3 logs taken when the problem was occurring. The problem happened also in past years, but in last a 1-2 years it happened less frequently

[alsa-devel] [PATCH - alsa-lib 1/1] Change card/pid get functions to return -ENOSYS if the kernel is too old
by Adam Goode 03 Jan '17

03 Jan '17

When trying to get the pid or card of a client, the get functions will return -1 if there is no pid or card for a client. Clients have zero or one of these, so -1 is correct for these cases. But we also need to detect the case where the kernel cannot tell us if there is a card or pid, so that userspace can fallback to probing this information in the old way.

[alsa-devel] [PATCH v4 0/3] ASoC/ARM: tegra: apalis t30/tk1/colibri t30: sgtl5000 audio
by Marcel Ziswiler 07 Nov '16

This series adds/integrates Freescale SGTL5000 analogue audio codec support. Changes in v4: - simple-audio-card does still not allow for more advanced use cases like Tegra SoCs - further platform drivers have been accepted since my last attempt (e.g. rt5677 one) - relevance for one further board the new Toradex Apalis TK1 - drop unused sound/jack.h include - in tegra_sgtl5000_driver_remove() pass return value of snd_soc_unregister_card() on to caller - no longer set owner property in platform_driver to THIS_MODULE - re-based/resend Changes in v3: - revert to not using simple-audio-card being incompatible with tegra - rebased to for-next Changes in v2: - using simple-audio-card as suggested by Fabio Marcel Ziswiler (3): ASoC: tegra: add tegra sgtl5000 machine driver ARM: tegra: apalis/colibri t30: integrate audio ARM: tegra: enable sgtl5000 audio .../bindings/sound/nvidia,tegra-audio-sgtl5000.txt | 42 ++++ arch/arm/boot/dts/tegra30-apalis.dtsi | 49 +++++ arch/arm/boot/dts/tegra30-colibri.dtsi | 49 +++++ arch/arm/configs/tegra_defconfig | 1 + sound/soc/tegra/Kconfig | 11 ++ sound/soc/tegra/Makefile | 2 + sound/soc/tegra/tegra_sgtl5000.c | 212 +++++++++++++++++++++ 7 files changed, 366 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/nvidia,tegra-audio-sgtl5000.txt create mode 100644 sound/soc/tegra/tegra_sgtl5000.c -- 2.5.5

[alsa-devel] CIP Discontinuity with snd-firewire-digi00x
by lin-alsa＠noblejury.com 01 Sep '16

01 Sep '16

All, I've been working to set up a Digi002 Rack mixer with Jack using the Alsa backend. Unfortunately, the mixer seems to desync or something after a few minutes - hours. dmesg gives me `snd-firewire-digi00x fw1.0: Detect discontinuity of CIP: XX XX` with XX XX replaced with various hex pairs. I'm not sure how to debug this, and any help would be much appreciated. Also, cat /proc/asound/card1/firewire/clock gives `Optical mode: adat Sampling Rate: 88200 Clock Source: internal` so I don't think it's an external clock issue. Lin
