[PATCH] ASoC: SOF: Intel: hda: unsolicited RIRB response
by Brent Lu 12 Jun '20

12 Jun '20

The loop implementation could not solve the unsolicited response issue because the RIRBSTS is cleared after leaving the snd_hdac_bus_update_rirb() function. So the next loop will fail the status test against the RIRB_INT_MASK and skip all the RIRB handling stuff. On the other hand, there alwasy could be unsolicited responses in the last loop regardless the number of loops. Clear the RIRB interrupt before handling it so unsolicited response could trigger another RIRB interrupt to handle it later.

[PATCH v2] ASoC: SOF: Intel: hda: unsolicited RIRB response
by Brent Lu 12 Jun '20

12 Jun '20

Port commit 6d011d5057ff ("ALSA: hda: Clear RIRB status before reading WP") from legacy HDA driver to fix the get response timeout issue. Current SOF driver does not suffer from this issue because sync write is enabled in hda_init. The issue will come back if the sync write is disabled for some reason.

alsa-gobject: ctl: obsolete abstract class for snd_ctl_elem_info structure
by GitHub pull_request - opened 12 Jun '20

12 Jun '20

alsa-project/alsa-gobject pull request #32 was opened from takaswie: In UAPI of Linux sound subsystem, snd_ctl_elem_info structure includes union member. Current implementation of ALSACtl uses abstract class (ALSACtlElemInfo) and concrete class (ALSACtlElemInfoBool and so on) to represent variation corresponding to each of union member. However, the design pattern is not convenient for some language bindings. For example, in Rust language, class-based inheritance is not supported. Gtk-rs project produces mechanism to upcast/downcast between super/sub classes and handles GObject class system. In my opinion, the code to upcast/downcast is a bit inconvenient to handle derivatives. This patchset obsoletes usage of abstract class for ALSACtl. The target is ALSACtlElemInfo. Some APIs are added into the object to retrieve data for integer/integer64/enumerated element type, then the object becomes concrete class.

[PATCH] dt-bindings: Fix more incorrect 'reg' property sizes in examples
by Rob Herring 11 Jun '20

11 Jun '20

The examples template is a 'simple-bus' with a size of 1 cell for had between 2 and 4 cells which really only errors on I2C or SPI type devices with a single cell. The easiest fix in most cases is to change the 'reg' property to 1 cell for address and size.

Clock sync problem?
by Laurence Tratt 11 Jun '20

11 Jun '20

Hello, I've found an interesting issue with an SSL2+ audio interface -- it plays and records fine (and, for the money, the sound quality is excellent!), but recording slowly but surely drifts over time. For example, if I record a click track in Audacity (or Ardour), play it through the interface and record it, and then line up the start of the recorded click track with the original, the two tracks will be around 5ms out of alignment after 30s. Interestingly, this problem does not happen with OpenBSD, where the two tracks line up precisely. My guess is that the problem is to do with implicit feedback in endpoints. I wondered if the problem was the same as with the MOTU M4, but enabling that quirk for the SSL2+ introduced some crackle, but didn't change the drift. I'm attaching a) the alsa-info file b) output from OpenBSD's kernel with debugging in the USB audio driver turned on in case that gives some clues as to what the two OS's and drivers might be doing differently. If anyone has any suggestions for how this problem might be addressed, I would be very grateful!
