[alsa-devel] [PATCH] ALSA: Fix prototype for snd_soc_dai_link.init() function pointer
by Timur Tabi 04 Jun '07

04 Jun '07

Change the snd_soc_dai_link.init() function to take a pointer to the corresponding snd_soc_dai_link structure, instead of a pointer to a snd_soc_codec structure. This allows the initialization function to initialize its own structure. Signed-off-by: Timur Tabi <timur(a)freescale.com> --- This is a fix for ALSA bug 3135 (https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3135). Since I don't have an ARM cross-compiler, and currently all ASoC drivers are for ARM platforms only, I'm not sure if this fix is correct. include/sound/soc.h | 2 +- sound/soc/at91/eti_b1_wm8731.c | 3 ++- sound/soc/pxa/corgi.c | 3 ++- sound/soc/pxa/poodle.c | 3 ++- sound/soc/pxa/spitz.c | 3 ++- sound/soc/pxa/tosa.c | 3 ++- sound/soc/soc-core.c | 2 +- 7 files changed, 12 insertions(+), 7 deletions(-) diff --git a/include/sound/soc.h b/include/sound/soc.h index db6edba..86e1b1d 100644 --- a/include/sound/soc.h +++ b/include/sound/soc.h @@ -410,7 +410,7 @@ struct snd_soc_dai_link { struct snd_soc_ops *ops; /* codec/machine specific init - e.g. add machine controls */ - int (*init)(struct snd_soc_codec *codec); + int (*init)(struct snd_soc_dai_link *codec); }; /* SoC machine */ diff --git a/sound/soc/at91/eti_b1_wm8731.c b/sound/soc/at91/eti_b1_wm8731.c index 820a676..a4f5a99 100644 --- a/sound/soc/at91/eti_b1_wm8731.c +++ b/sound/soc/at91/eti_b1_wm8731.c @@ -216,9 +216,10 @@ static const char *intercon[][3] = { /* * Logic for a wm8731 as connected on a Endrelia ETI-B1 board. */ -static int eti_b1_wm8731_init(struct snd_soc_codec *codec) +static int eti_b1_wm8731_init(struct snd_soc_dai_link *dai) { int i; + struct snd_soc_codec *codec = dai->codec_dai->codec; DBG("eti_b1_wm8731_init() called\n"); diff --git a/sound/soc/pxa/corgi.c b/sound/soc/pxa/corgi.c index 5ee51a9..43237f9 100644 --- a/sound/soc/pxa/corgi.c +++ b/sound/soc/pxa/corgi.c @@ -286,9 +286,10 @@ static const struct snd_kcontrol_new wm8731_corgi_controls[] = { /* * Logic for a wm8731 as connected on a Sharp SL-C7x0 Device */ -static int corgi_wm8731_init(struct snd_soc_codec *codec) +static int corgi_wm8731_init(struct snd_soc_dai_link *dai) { int i, err; + struct snd_soc_codec *codec = dai->codec_dai->codec; snd_soc_dapm_set_endpoint(codec, "LLINEIN", 0); snd_soc_dapm_set_endpoint(codec, "RLINEIN", 0); diff --git a/sound/soc/pxa/poodle.c b/sound/soc/pxa/poodle.c index 0915cf7..5e8cb76 100644 --- a/sound/soc/pxa/poodle.c +++ b/sound/soc/pxa/poodle.c @@ -246,9 +246,10 @@ static const snd_kcontrol_new_t wm8731_poodle_controls[] = { /* * Logic for a wm8731 as connected on a Sharp SL-C7x0 Device */ -static int poodle_wm8731_init(struct snd_soc_codec *codec) +static int poodle_wm8731_init(struct snd_soc_dai_link *dai) { int i, err; + struct snd_soc_codec *codec = dai->codec_dai->codec; snd_soc_dapm_set_endpoint(codec, "LLINEIN", 0); snd_soc_dapm_set_endpoint(codec, "RLINEIN", 0); diff --git a/sound/soc/pxa/spitz.c b/sound/soc/pxa/spitz.c index 80e8210..95dcaa4 100644 --- a/sound/soc/pxa/spitz.c +++ b/sound/soc/pxa/spitz.c @@ -292,9 +292,10 @@ static const struct snd_kcontrol_new wm8750_spitz_controls[] = { /* * Logic for a wm8750 as connected on a Sharp SL-Cxx00 Device */ -static int spitz_wm8750_init(struct snd_soc_codec *codec) +static int spitz_wm8750_init(struct snd_soc_dai_link *dai) { int i, err; + struct snd_soc_codec *codec = dai->codec_dai->codec; /* NC codec pins */ snd_soc_dapm_set_endpoint(codec, "RINPUT1", 0); diff --git a/sound/soc/pxa/tosa.c b/sound/soc/pxa/tosa.c index 5504e30..b438349 100644 --- a/sound/soc/pxa/tosa.c +++ b/sound/soc/pxa/tosa.c @@ -192,9 +192,10 @@ static const struct snd_kcontrol_new tosa_controls[] = { tosa_set_spk), }; -static int tosa_ac97_init(struct snd_soc_codec *codec) +static int tosa_ac97_init(struct snd_soc_dai_link *dai) { int i, err; + struct snd_soc_codec *codec = dai->codec_dai->codec; snd_soc_dapm_set_endpoint(codec, "OUT3", 0); snd_soc_dapm_set_endpoint(codec, "MONOOUT", 0); diff --git a/sound/soc/soc-core.c b/sound/soc/soc-core.c index 92d5d91..654a517 100644 --- a/sound/soc/soc-core.c +++ b/sound/soc/soc-core.c @@ -1093,7 +1093,7 @@ int snd_soc_register_card(struct snd_soc_device *socdev) mutex_lock(&codec->mutex); for(i = 0; i < machine->num_links; i++) { if (socdev->machine->dai_link[i].init) { - err = socdev->machine->dai_link[i].init(codec); + err = socdev->machine->dai_link[i].init(&machine->dai_link[i]); if (err < 0) { printk(KERN_ERR "asoc: failed to init %s\n", socdev->machine->dai_link[i].stream_name); -- 1.5.0.2.260.g2eb065

[alsa-devel] SALSA-Lib version 0.0.1 release
by Takashi Iwai 04 Jun '07

04 Jun '07

Hi all, I created a small replacement of ALSA-library, mainly for embedded systems with limited resources. The library is named as "SALSA-Lib" (too easy, eh?) It has no plugin layer but only hw layer, thus no sexy features like dmix and format conversions are available. It supports no shiny and complex configuration files. And it supports no sequencer. The only goal of this library is the reduction of the size of library and running binaries by inlining functions with direct syscalls. The library is designed to be source-level API compatible with the normal alsa-lib 1.0.14. Note that it is _not_ designed to be binary-compatible at all, and it will be never so. The first released version 0.0.1 is available at: ftp://ftp.suse.com/pub/people/tiwai/salsa-lib/salsa-lib-0.0.1.tar.bz2 The package is released under LGPL as well as the original alsa-lib. I've tested it only on i386, and tests on other architectures would be greatly appreciated. (And, no, I didn't make it on HG tree yet.) Takashi

[alsa-devel] Datasheet Needed
by chris＠idlelion.net 04 Jun '07

04 Jun '07

(working on bug #305) I'm looking for a proper datasheet on the Cirrus Logic / Crystal Semiconductor CS4624 (or CS4622) sound chip. It's used in a number of popular laptops made around 1999-2001. I don't need the 7- or 8-page feature list, or the 30 (or so) page reference design document. I need register lists and theory of operation and a discussion of power modes. The chip was end-of-lifed in 2004. Many thanks, Chris

[alsa-devel] Problem with ncurses and alsamixer (cannot open terminal: vt100 or xterm)
by David Topper 04 Jun '07

04 Jun '07

I finally managed to get the alsa-1.0.4 utils to compile on an ARM based SBC. When I launch alsamixer, however, I get an error: Error opening terminal: xterm When I ssh into the board. Or: Error opening terminal: vt100 When connected via serial cable. I suspect this has something to do with the linking (or lack thereof) of alsamixer for ncurses. The ncurrses library, by the way, I cross compiled with the following command: CC=/opt/crosstool/arm-unknown-linux-gnu/gcc-3.3.4-glibc-2.3.2/bin/arm-unknown-linux-gnu-gcc ./configure --host=arm-linux --prefix=/home/topper/ts-packages/ --exec-prefix=/home/topper/ts-packages/ But for the alsa utils, I simple ran ./configure, and the script detected the ncurses library, ran through and compiled. Yet, something seems amuck because: root@ts7000:root# ldd /bin/alsamixer libasound.so.2 => /lib/libasound.so.2 (0x2aac8000) libm.so.6 => /lib/libm.so.6 (0x2ab6f000) libdl.so.2 => /lib/libdl.so.2 (0x2abe9000) libpthread.so.0 => /lib/libpthread.so.0 (0x2abf3000) libc.so.6 => /lib/libc.so.6 (0x2ac4b000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x2aaab000) Whereas on my Linux Intel laptop: awn:~$ ldd /usr/bin/alsamixer libncurses.so.5 => /lib/libncurses.so.5 (0x4002c000) libasound.so.2 => /usr/lib/libasound.so.2 (0x40069000) libm.so.6 => /lib/libm.so.6 (0x4010d000) libdl.so.2 => /lib/libdl.so.2 (0x40130000) libpthread.so.0 => /lib/libpthread.so.0 (0x40133000) libc.so.6 => /lib/libc.so.6 (0x40184000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) So I have two questions: 1. How might ensure proper linking of the ncurses library. 2. Is there another way to tell alsa to activate various cards, set volume, etc.. so I can test to see if the alsa driver is even working on this board.

by Jaroslav Kysela 04 Jun '07

04 Jun '07

Hello all, I put 1.0.14-final test packages to ftp://ftp.alsa-project.org/pub/testing Note that these packages are not an official release. They are indended for compilation tests. Anyway, if you find a compilation (not functionality) issue, please, let me know ASAP through e-mail. I'm going to release 1.0.14 packages on next Monday. Note for alsa developers: Please, no more HG repository updates until packages are released.

[alsa-devel] snd_hda_intel: Conexant CX20551 (Waikiki)
by Edwin Smulders 03 Jun '07

03 Jun '07

Hi, I believe there's still a problem with the HDA Intel chip Conexant CX20551 (Waikiki) not working. However, im not entirely sure the problem the problem is with alsa, because it starts working when i boot with acpi=off (a fix suggested on the ubuntu forums, but not quite useful on a laptop [plus, it breaks my ethernet]) The reason I'm mailing is, can you confirm this is something alsa can/should/will fix or are we all looking in the wrong direction and this is really an acpi problem? If you can fix this or know of something that might work, I would be happy to hear it. I've attached my lspci -nv and cat /proc/asound/card0/codec\#* just in case. I would be happy to give you any more info you might need. ~~ Edwin
