[alsa-devel] simplify simple-card
by Kuninori Morimoto 23 Mar '15

23 Mar '15

Hi Mark, all I want to create new sound card driver which supports DAPM. But I can't use simple-card driver for this purpose because DT binding issue. I guess, this new sound card can use/share simple-card functions. OTOH, simple-card is not "simple" today :( Basically, main purpose of simple-card / new sound card is binding CPU/Codec settings to ALSA SoC framework. But we have many pattern for it. From DT bindings point of view, we can/should use same DT bindings for same settings. Now, simple-card is supporting - single CPU/Codec - multi CPU/Codec - more feature... My opinion is that complex code has un-understandable bug. So, how about simplify simple-card, what do you think about this idea ? We separate current simple-card to common parts, and, simple-card specific parts. basically, common parts controls DT bindings and ALSA SoC settings. sound card specific parts cares each own feature. I don't know about naming, but these audio card can use same bindings via common functions. - common : basic common functions - simple-audio-card : existing driver, keep as-is for compatible reason - single-audio-card : single CPU/Codec sound card. simplified from simple-audio-card - multi-audio-card : multi CPU/Codec sound card. simplified from simple-audio-card - fixrate-audio-card : new sound card same as single-audio-card, but it needs sampling-rate-convert via DAPM, - chain-audio-card : DAPM card (?) - .... My idea is taht we can replace current "simple-audio-card" to "single-audio-card", or, "simple-audio-card" to "multi-audio-card" on DT. Best regards --- Kuninori Morimoto

[alsa-devel] [RFC][PATCH 00/13] alsa-tools: libhinawa for control applications of FireWire devices
by Takashi Sakamoto 20 Mar '15

20 Mar '15

This is RFC for a new library into alsa-tools. ALSA in Linux 3.16 or later extends a support for FireWire sound devices. Currently ALSA drivers supports streaming functionality only, while most of these devices require software implementation to control its internal DSP. The way to achieve this is to transfer byte sequence to the unit and wait byte sequence which the unit transfers if required. This library, libhinawa, just support these operations, nothing others. The supported types of transactions are: - IEEE 1394 read transaction - IEEE 1394 write transaction - IEEE 1394 lock transaction - IEC 61883-1 FCP transaction - Echo Fireworks transaction (with a help of snd-fireworks kernel driver) - Dice notification (with a help of snd-dice kernel driver) To help new developers, this library supports GObject Introspection for language bindings. The main logic of applications can be written with preferred languages such as Python, Ruby, Perl and so on. In the end of this patchset, some Python scripts with Gtk+, Qt4 and Qt5 are committed as samples. This is my first development with GNU Autotools, GLib/GObject and GObject Introspection. Furthermore, I'm a beginner of FireWire subsystem programming. I'm happy to receive your comments, especially: - the way to write Linux version dependency in configure.ac - the way of libtool versioning - the value of poll timeout in fw_unit/snd_unit - the value of thread condition timeout in fw_fcp/snd_dice/snd_efw - improvements of 'unit_query' object - any programming mistakes (threading and so on...) Regards Takashi Sakamoto (13): libhinawa: add build definitions libhinawa: add hinawa context libhinawa: support GTK-Doc to generate references libhinawa: add 'fw_unit' object as a listener for FireWire unit libhinawa: support GObject Introspection for language bindings libhinawa: add 'fw_resp' object as a responder for FireWire transaction libhinawa: add 'fw_req' object as requester for FireWire transaction libhinawa: add 'fw_fcp' object as a helper of FCP transaction libhinawa: add 'snd_unit' object as a listener for ALSA FireWire devices libhinawa: add 'snd_dice' object as a helper for Dice notification libhinawa: add 'snd_efw' object as a helper for EFW transaction libhinawa: add 'unit_query' as a query for ALSA FireWire devices libhinawa: add sample scripts Makefile | 2 +- libhinawa/AUTHORS | 1 + libhinawa/COPYING | 504 ++++++++++++++++++++++++++++ libhinawa/ChangeLog | 5 + libhinawa/Makefile.am | 6 + libhinawa/NEWS | 0 libhinawa/README | 30 ++ libhinawa/autogen.sh | 11 + libhinawa/configure.ac | 68 ++++ libhinawa/doc/Makefile.am | 2 + libhinawa/doc/reference/Makefile.am | 46 +++ libhinawa/doc/reference/hinawa-docs.sgml | 47 +++ libhinawa/doc/reference/version.xml.in | 1 + libhinawa/samples/gtk3.py | 190 +++++++++++ libhinawa/samples/qt4.py | 206 ++++++++++++ libhinawa/samples/qt5.py | 192 +++++++++++ libhinawa/samples/run.sh | 15 + libhinawa/src/Makefile.am | 97 ++++++ libhinawa/src/backport.h | 41 +++ libhinawa/src/fw_fcp.c | 282 ++++++++++++++++ libhinawa/src/fw_fcp.h | 58 ++++ libhinawa/src/fw_req.c | 265 +++++++++++++++ libhinawa/src/fw_req.h | 56 ++++ libhinawa/src/fw_resp.c | 232 +++++++++++++ libhinawa/src/fw_resp.h | 51 +++ libhinawa/src/fw_unit.c | 343 +++++++++++++++++++ libhinawa/src/fw_unit.h | 52 +++ libhinawa/src/hinawa_context.c | 60 ++++ libhinawa/src/hinawa_context.h | 10 + libhinawa/src/internal.h | 31 ++ libhinawa/src/snd_dice.c | 195 +++++++++++ libhinawa/src/snd_dice.h | 53 +++ libhinawa/src/snd_efw.c | 315 ++++++++++++++++++ libhinawa/src/snd_efw.h | 54 +++ libhinawa/src/snd_unit.c | 548 +++++++++++++++++++++++++++++++ libhinawa/src/snd_unit.h | 69 ++++ libhinawa/src/unit_query.c | 116 +++++++ libhinawa/src/unit_query.h | 48 +++ 38 files changed, 4301 insertions(+), 1 deletion(-) create mode 100644 libhinawa/AUTHORS create mode 100644 libhinawa/COPYING create mode 100644 libhinawa/ChangeLog create mode 100644 libhinawa/Makefile.am create mode 100644 libhinawa/NEWS create mode 100644 libhinawa/README create mode 100755 libhinawa/autogen.sh create mode 100644 libhinawa/configure.ac create mode 100644 libhinawa/doc/Makefile.am create mode 100644 libhinawa/doc/reference/Makefile.am create mode 100644 libhinawa/doc/reference/hinawa-docs.sgml create mode 100644 libhinawa/doc/reference/version.xml.in create mode 100755 libhinawa/samples/gtk3.py create mode 100755 libhinawa/samples/qt4.py create mode 100755 libhinawa/samples/qt5.py create mode 100755 libhinawa/samples/run.sh create mode 100644 libhinawa/src/Makefile.am create mode 100644 libhinawa/src/backport.h create mode 100644 libhinawa/src/fw_fcp.c create mode 100644 libhinawa/src/fw_fcp.h create mode 100644 libhinawa/src/fw_req.c create mode 100644 libhinawa/src/fw_req.h create mode 100644 libhinawa/src/fw_resp.c create mode 100644 libhinawa/src/fw_resp.h create mode 100644 libhinawa/src/fw_unit.c create mode 100644 libhinawa/src/fw_unit.h create mode 100644 libhinawa/src/hinawa_context.c create mode 100644 libhinawa/src/hinawa_context.h create mode 100644 libhinawa/src/internal.h create mode 100644 libhinawa/src/snd_dice.c create mode 100644 libhinawa/src/snd_dice.h create mode 100644 libhinawa/src/snd_efw.c create mode 100644 libhinawa/src/snd_efw.h create mode 100644 libhinawa/src/snd_unit.c create mode 100644 libhinawa/src/snd_unit.h create mode 100644 libhinawa/src/unit_query.c create mode 100644 libhinawa/src/unit_query.h -- 2.1.0

[alsa-devel] [PATCH v9] ASoC: dapm: add code to configure dai link parameters
by Nikesh Oswal 17 Mar '15

17 Mar '15

dai-link params for codec-codec links were fixed. The fixed link between codec and another chip which may be another codec, baseband, bluetooth codec etc may require run time configuaration changes. This change provides an optional alsa control to select one of the params from a list of params.

[alsa-devel] Issues and/or possible bugs in alsa
by Yomi Ogunwumi 15 Mar '15

15 Mar '15

Hello. I seem to have run into a few issues with alsa. First, when I plug my headphones into my laptop, sound continues to play out of the speakers and doesn't switch over to (or unmute) the headphones. Auto-Mute Mode is enabled in alsamixer. The same thing happens when I unplug the headphones, it doesn't switch over to the speakers. I have to do the same thing I described above, (no unmuting, I just have to turn up the volume for the speakers in alsamixer.) Second. When I plug in these headphones, I can't use the internal microphone on this laptop, it mutes. (AFAICT) These headphones do not have a microphone built in, they're just an ordinary pair of headphones. However, I was given a workaround in #alsa on freenode. In order to use the laptop's internal microphone with my headphones plugged in, I have to do : sudo hda-verb /dev/snd/hwC1D0 0x22 SET_CONNECT_SEL 6 — it works, but it isn't really ideal. alsa-info is here : https://gist.github.com/Yomi0/9bfc3e72588cf8a35811 The first file in that gist is alsa-info with headphones and the second is without headphones. Third. This is just a question. Is this : https://bugs.freedesktop.org/show_bug.cgi?id=86676 actually a pulseaudio bug, or is it an issue with alsa? I'm only asking since Raymond linked something that seemed to belong to the alsa project. Thank you. -- *Yomi*

[alsa-devel] [PATCH 0/8] Fix struct clk pointer comparing
by Shawn Guo 12 Mar '15

12 Mar '15

On the first day back from Chinese new year holiday, I got a regression report from rmk, saying Ethernet stops working on HimmingBoard with v4.0-rc1. I read through the thread [1] and found a couple of i.MX audio drivers are also affected per Stephen's Coccinelle report. That's why I came up with this series based on Quentin's structclk.cocci, Stephen's result and Mike's input (thanks all). The first two patches are run-time tested and all others are compile-tested only.
