by Takashi Sakamoto 22 Jul '15

22 Jul '15

Hi, This patchset is for three new drivers and related modification to firewire-lib module. Overview: * Patch 01-02: for firewire-lib, to split AMDTP layer to two parts * Patch 03-07: for firewire-lib, to add MIDI asynchronous transaction * Patch 08-16: for firewire-digi00x, a new driver for Digi 002/003 family * Patch 17-26: for firewire-tascam, a new driver for TASCAM FireWire series * Patch 27-28: for firewire-lib, to add SPH field in CIP header support * Patch 29-37: for firewire-motu, a new driver for MOTU FireWire series Status: * firewire-digi00x: * well-prepared, except for final testing with Digi 003 series * firewire-tascam: * well-prepared, except for conversion of controll messages to MIDI * firewire-motu: * experimental, for preview to developers As the other my RFCs, I prepare for a branch in my backport repository, to make it easy to test this patchset. https://github.com/takaswie/snd-firewire-improve/tree/amdtp-variants I'm happy if receiving your comments, reviews, tests and your patches. I have a plan to posting patches again to merging these well-prepared drivers till next merge window for Linux 4.3.

[alsa-devel] pulseaudio external mic jack detection - ASoC based card
by maruthi srinivas 22 Jul '15

22 Jul '15

Hi, I have a issue with mic jack status in Ubuntu "sound settings" UI. When external mic is removed, UI still shows Mic. When compared to HD Azalia driver, UI shouldn't show any external Mic jack information, if it is removed. Codec driver I use reports jack status properly and uses snd_soc_jack_report(). /proc/interrupts, /dev/input/eventX reflects jack activity. But the same is not reflected in UI. I want to know how pulseaudio detect jack status for drivers which follow ALSA SoC architecture. Does it read from any event from /dev/input/eventX ? Please help in understanding. Regards, Maruthi

[alsa-devel] [PATCH] ASoC: kirkwood: prevent double streaming
by Jean-Francois Moine 22 Jul '15

22 Jul '15

The kirkwood audio subsystem presents 2 PCM's for one source. Streaming on a second PCM while the first one is active cuts this last one. Then, ending the last stream gives a kernel trap in free_irq().

[alsa-devel] [PATCH 1/2] ASoC: dapm: Add helper function to free a widget
by Lars-Peter Clausen 22 Jul '15

22 Jul '15

snd_soc_tplg_widget_remove_all() has a verbatim copy of an older version of the widget freeing code from dapm_free_widgets(). Add a new helper function that takes care of freeing a widget and use it in both places. This removes the duplicated code and also makes sure that future changes to the widget freeing code only have to be made in one location.

[alsa-devel] [PATCH] ALSA: hda - remove one pin from ALC292_STANDARD_PINS
by Hui Wang 22 Jul '15

22 Jul '15

One more Dell laptop with alc293 codec needs ALC293_FIXUP_DELL1_MIC_NO_PRESENCE, but the pin 0x1e does not match the corresponding one in the ALC292_STANDARD_PINS. To use this macro for this machine, we need to remove pin 0x1e from it.

[alsa-devel] [PATCH] ASoC: dapm: Don't add prefix to widget stream name
by Lars-Peter Clausen 21 Jul '15

21 Jul '15

Commit fdb6eb0a1287 ("ASoC: dapm: Modify widget stream name according to prefix") fixed the case where a DAPM route between a DAI widget and a DAC/ADC/AIF widget with a matching stream name was not created when the DAPM context was using a prefix. Unfortunately the patch introduced a few issues on its own like leaking the dynamically allocated stream name memory and also not checking whether the allocation succeeded in the first place. It is also incomplete in that it still does not handle the case where stream name of the widget is a substring of the stream name of the DAI, which is explicitly allowed and works fine if no DAPM prefix is used. Revert the commit and take a slightly different approach to solving the issue. Instead of comparing the widget's stream name to the name of the DAI widget compare it to the stream name of the DAI widget. The stream name of the DAI widget is identical to the name of the DAI widget except that it wont have the DAPM prefix added. So this approach behaves identical regardless to whether the DAPM context uses a prefix or not. We don't have to worry about potentially matching with a widget with the same stream name, but from a different DAPM context with a different prefix, since the code already makes sure that both the DAI widget and the matched widget are from the same DAPM context.

[alsa-devel] [patch] ASoC: max98925: reading beyond the end of the array
by Dan Carpenter 21 Jul '15

21 Jul '15

Debug prints are seldom useful and this one has an annoying thing where it reads one space beyond the end of the array on error.
