presonus StudioLive 24.4.2
by m.eik michalke 19 Jun '20

19 Jun '20

hi, i'm trying to get a presonus StudioLive 24.4.2 up and running: https://www.presonus.com/products/studiolive-24.4.2 so far i'm partly successful -- looks like the board is automatically detected and supported by the firewire dice module. however, i'm only offered 16 of the 24 supported audio channels. in the list of soundcards it is merely shown as "studiolive" without further info on the model. i wasn't able to find further info on this board's status with regards to alsa, so if there's documentation on this somewhere, could someone please point me to it? in case that as of now the studiolive isn't officially supported or the above behavior is due to the fact that so far only the 16.4.2 is known to the module, i'm willing to help as far as i can ;) i hope that already seeing 16 channels is a good point to start and that it's not too hard to make the remaining 8 show up as well... best regards :: m.eik

[PATCH AUTOSEL 5.7 055/388] ASoC: SOF: Do nothing when DSP PM callbacks are not set
by Sasha Levin 18 Jun '20

18 Jun '20

From: Daniel Baluta <daniel.baluta(a)nxp.com> [ Upstream commit c26fde3b15ed41f5f452f1da727795f787833287 ] This provides a better separation between runtime and PM sleep callbacks. Only do nothing if given runtime flag is set and calback is not set. With the current implementation, if PM sleep callback is set but runtime callback is not set then at runtime resume we reload the firmware even if we do not support runtime resume callback.

[PATCH RESEND 0/3] ASoC: Intel: simplify driver/card names for SOF/UCM integration
by Pierre-Louis Bossart 18 Jun '20

18 Jun '20

As suggested by Jaroslav, this patchset simplifies legacy cards compiled with SOF: they now expose an 'SOF' driver name and an 'sof-bytcht <codec>' card name. UCM uses this driver name and additionally checks for the card name to load a configuration shared with the SST driver. This patchset is just a rename with no functionality change. There is no modification when SOF is not used, and Kconfig for SOF are disabled when SST is enabled so no risk of interference. This helps make 5.9 the first kernel version where SOF 'just works'(tm) on legacy platforms with no additional configuration needed (as is already the case with more recent HDaudio+DMIC platforms). Thanks to Jaroslav for all the hard work on the alsa-lib/UCM side (the majority of the configs are already merged in alsa-ucm-conf, only minor updates are in-flight for max98090 and broadwell). Patches sent initially on May 29, probably missed with the merge window. No changes except for the addition of Jaroslav's Reviewed-by tag.

In mobile, a co-processor is used when using USB audio to improve power consumption. hooking is required for sync-up when operating the co-processor. So register call-back function. The main operation of the call-back function is as follows: - Initialize the co-processor by transmitting data when initializing. - Change the co-processor setting value through the interface function. - Configure sampling rate - pcm open/close Bug: 156315379 Change-Id: I32e1dd408e64aaef68ee06c480c4b4d4c95546dc Signed-off-by: JaeHun Jung <jh0801.jung(a)samsung.com> --- sound/usb/card.c | 16 ++++++++++++++++ sound/usb/card.h | 1 + sound/usb/clock.c | 5 +++++ sound/usb/pcm.c | 33 +++++++++++++++++++++++++++++++++ sound/usb/usbaudio.h | 30 ++++++++++++++++++++++++++++++ 5 files changed, 85 insertions(+) diff --git a/sound/usb/card.c b/sound/usb/card.c index fd6fd17..2f3fa14 100644 --- a/sound/usb/card.c +++ b/sound/usb/card.c @@ -111,6 +111,7 @@ MODULE_PARM_DESC(skip_validation, "Skip unit descriptor validation (default: no) static DEFINE_MUTEX(register_mutex); static struct snd_usb_audio *usb_chip[SNDRV_CARDS]; static struct usb_driver usb_audio_driver; +struct snd_usb_audio_vendor_ops *usb_audio_ops; /* * disconnect streams @@ -210,6 +211,12 @@ static int snd_usb_create_stream(struct snd_usb_audio *chip, int ctrlif, int int return 0; } +void snd_set_vender_interface(struct snd_usb_audio_vendor_ops *vendor_ops) +{ + usb_audio_ops = vendor_ops; +} +EXPORT_SYMBOL_GPL(snd_set_vender_interface); + /* * parse audio control descriptor and create pcm/midi streams */ @@ -598,6 +605,9 @@ static int usb_audio_probe(struct usb_interface *intf, if (err < 0) return err; + if (usb_audio_ops && usb_audio_ops->vendor_conn) + usb_audio_ops->vendor_conn(intf, dev); + /* * found a config. now register to ALSA */ @@ -653,6 +663,9 @@ static int usb_audio_probe(struct usb_interface *intf, } dev_set_drvdata(&dev->dev, chip); + if (usb_audio_ops && usb_audio_ops->vendor_usb_add_ctls) + usb_audio_ops->vendor_usb_add_ctls(chip, 0); + /* * For devices with more than one control interface, we assume the * first contains the audio controls.

[PATCH 2/2] ASoC: amd: closing specific instance.
by Ravulapati Vishnu vardhan rao 18 Jun '20

18 Jun '20

The steps to reproduce: Record from the internal mic : (arecord -D hw:1,2 -f dat /dev/null -V stereos) Record from the headphone mic: (arecord -D hw:1,0 -f dat /dev/null -V stereos) Kill the recording from internal mic. We can see the recording from the headphone mic is broken. This patch rectifies the issue reported.
