Question: is it possible to subscribe a port to system announcer ?
by GitHub issues - opened 01 Mar '23

alsa-project/alsa-python issue #7 was opened from Houston4444: Hi. I try to add ALSA support to [Patchance](https://github.com/Houston4444/Patchance). I 'd like to create a port capable to receive events as SEQ_EVENT_PORT_START or SEQ_EVENT_PORT_EXIT in order to get a complete graph. I see in patchage source code (C++) that it uses 'snd_seq_connect_from' function to enable this events. Is it possible in python with this lib ? Thanks.

[PATCH] ASoC: mediatek: add missing initialization
by Trevor Wu 01 Mar '23

01 Mar '23

In etdm dai driver, dai_etdm_parse_of() function is used to parse dts properties to get parameters. There are two for-loops which are sepearately for all etdm and etdm input only cases. In etdm in only loop, dai_id is not initialized, so it keeps the value intiliazed in another loop. In the patch, add the missing initialization to fix the unexpected parsing problem.

[Patch] sound/aoa: Add support for iBook G4 (powerbook6,5)
by Thaison Nguyen 01 Mar '23

01 Mar '23

The audio on my iBook G4 (powerbook65) has not been working. This is because the ids of the device were missing in the aoa audio driver. With this patch, the IDs of Powerbook6,4 and Powerbook6,5 are added to the driver.

[PATCH v3 0/3] ASoC: mchp-pdmc: fix poc noises when starting capture
by Claudiu Beznea 28 Feb '23

28 Feb '23

To start capture on Microchip PDMC the enable bits for each supported microphone need to be set. After this bit is set the PDMC starts to receive data from microphones and it considers this data as valid data. Thus if microphones are not ready the PDMC captures anyway data from its lines. This data is interpreted by the human ear as poc noises. To avoid this the following software workaround need to be applied when starting capture: 1/ enable PDMC channel 2/ wait 150ms 3/ execute 16 dummy reads from RHR 4/ clear interrupts 5/ enable interrupts 6/ enable DMA channel For this workaround to work step 6 need to be executed at the end. For step 6 was added patch 1/3 from this series. With this, component DAI driver sets its struct snd_soc_component_driver::start_dma_last = 1 and proper action is taken based on this flag when starting DAI trigger vs DMA. Thank you, Claudiu Beznea Changes in v3: - update the commit message of patch 2/3 to be more descriptive - in patch 3/3 initialize dd->startup_delay_us before calling of_property_read_u32() and don't check its return value; property is optional and the the default value is 150ms Changes in v2: - patch 1/3 from v1 is now "ASoC: soc-pcm: add option to start DMA after DAI" - pass start_dma_last from component DAI driver object (struct snd_soc_component_driver::start_dma_last); adapt patch 3/3 after this; - in patch 1/3 s/Do we need to start dma first/Do we need to start dma last in comment from soc_pcm_trigger() - collect review tag from Krzysztof Claudiu Beznea (3): ASoC: soc-pcm: add option to start DMA after DAI ASoC: dt-bindings: sama7g5-pdmc: add microchip,startup-delay-us binding ASoC: mchp-pdmc: fix poc noise at capture startup Claudiu Beznea (3): ASoC: soc-pcm: add option to start DMA after DAI ASoC: dt-bindings: sama7g5-pdmc: add microchip,startup-delay-us binding ASoC: mchp-pdmc: fix poc noise at capture startup .../sound/microchip,sama7g5-pdmc.yaml | 6 +++ include/sound/soc-component.h | 2 + sound/soc/atmel/mchp-pdmc.c | 53 +++++++++++++++++-- sound/soc/soc-pcm.c | 27 ++++++++-- 4 files changed, 78 insertions(+), 10 deletions(-) -- 2.34.1

[PATCH] ASoC: sam9g20ek: Disable capture unless building with microphone input
by Mark Brown 28 Feb '23

28 Feb '23

Without modification the AT91SAM9G20-EK has no capture support, none of the inputs of the CODEC are wired to anything to useful and there are no paths supporting loopback. Since the audio is clocked from the CODEC and the DAPM inputs are marked as unusable this means that capture will fail to transfer any data as the ADC path can't be powered up. Flag this in the device description so apps don't see unusable capture support, guarded with the existing optional define for mic input.
