[alsa-devel] PATCH: [plug] Move fast_ops copy after slave configuration.
by Reilly Grant 30 Sep '11

30 Sep '11

The plug plugin copies the fast_ops structure and fast_op_arg from its slave PCM on initialization and after inserting a new plugin. This works unless the slave PCM is also an instance of the plug plugin because plug can change its fast_ops structure during _snd_pcm_hw_params. Instead of copying fast_ops in snd_pcm_plug_insert_plugins wait until the end of snd_pcm_plug_hw_params when the slave has been fully initialized. This fixes a crash when two instances of plug are instantiated back to back and the format conversion plugin inserted by the second is skipped by the first because the fast_ops pointer is not properly updated. --- src/pcm/pcm_plug.c | 5 +++-- 1 files changed, 3 insertions(+), 2 deletions(-) diff --git a/src/pcm/pcm_plug.c b/src/pcm/pcm_plug.c index e9d2923..72456d5 100644 --- a/src/pcm/pcm_plug.c +++ b/src/pcm/pcm_plug.c @@ -659,8 +659,6 @@ static int snd_pcm_plug_insert_plugins(snd_pcm_t *pcm, } if (err) { plug->gen.slave = new; - pcm->fast_ops = new->fast_ops; - pcm->fast_op_arg = new->fast_op_arg; } k++; } @@ -1049,6 +1047,9 @@ static int snd_pcm_plug_hw_params(snd_pcm_t *pcm, snd_pcm_hw_params_t *params) } snd_pcm_unlink_hw_ptr(pcm, plug->req_slave); snd_pcm_unlink_appl_ptr(pcm, plug->req_slave); + + pcm->fast_ops = slave->fast_ops; + pcm->fast_op_arg = slave->fast_op_arg; snd_pcm_link_hw_ptr(pcm, slave); snd_pcm_link_appl_ptr(pcm, slave); return 0; -- 1.7.3.4

[alsa-devel] Report by PulseAudio: `alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.`
by Paul Menzel 29 Sep '11

Dear ALSA developers, I got the following messages in `/var/log/syslog`. Aug 24 09:29:05 doe pulseaudio[2735]: core-util.c: Home directory /etc/timidity not ours. Aug 24 09:29:05 doe pulseaudio[2735]: lock-autospawn.c: Cannot access autospawn lock. Aug 24 09:29:05 doe pulseaudio[2735]: main.c: Failed to acquire autospawn lock Aug 24 13:00:33 doe pulseaudio[3118]: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! Aug 24 13:00:33 doe pulseaudio[3118]: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers. Aug 24 13:00:33 doe pulseaudio[3118]: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. Additionally I am seeing the a lot of the following messages in the kernel ring buffer (`dmesg`) [14293.422591] hda-intel: spurious response 0x0:0x0, last cmd=0x1f0004 [14293.422612] hda-intel: spurious response 0x0:0x0, last cmd=0x1f0004 [14293.422633] hda-intel: spurious response 0xe0160:0x0, last cmd=0x1f0004 [14293.422653] hda-intel: spurious response 0x1:0x0, last cmd=0x1f0004 [14293.422675] hda-intel: spurious response 0x0:0x0, last cmd=0x1f0004 [14293.422695] hda-intel: spurious response 0x0:0x0, last cmd=0x1f0004 [14293.422716] hda-intel: spurious response 0x20025:0x0, last cmd=0x1f0004 but I do not know if this is related. I am using the Debian Linux kernel 2.6.32 which includes all longterm patches up to 2.6.32.40. So only the ALSA drivers version 1.0.21 are used. Is there a commit that addresses the above behavior and which could be backported? Please find the output of `alsa-info.sh` [1] at the end.

[alsa-devel] dmix problems with analog out (HDMI out works fine with dmix)
by Robert Krakora 29 Sep '11

29 Sep '11

Hi All, I am using ALSA 1.0.24 with the attached asound.conf. I am attempting to share (mix) the analog output between Asterisk and aplay. However, when Asterisk is running, my application throws an error when attempting to play a wave file via aplay. If I stop Asterisk, aplay plays the wave file just fine. If I remove the asound.conf file, Asterisk and aplay are both happy and share the analog output just find with the default ALSA dmix implementation. However, we need this asound.conf to work for us for other reasons. What is wrong with it. I have even tried replacing dmix with dshare and get the same bad behavior. We are running CentOS 6.0. As a caveat, I am attempting to use dmix with analog audio. If I use it with HDMI audio, it works flawlessly (same asound.conf with tweek to specify HDMI). Thanks in advance for your help.

[alsa-devel] [PATCH v2 0/4] ASoC: twl6040: Gain ramp code cleanups
by Peter Ujfalusi 29 Sep '11

29 Sep '11

Hello, Changes since v1: - Loop counters cleaned, commented in patch 2 - Use cancel_delayed_work_sync to make sure that we do not have pending work, or executing work when modifying the variables used by the ramp code. - patches already taken left out. Intro from v1: the following series cleans up the gain ramp code found in the twl6040 codec driver. Main changes: - use one workqueue for the twl6040 codec driver (instead of the original 3) - Delays between the steps does not need to be different among the range. I assume, that the original code contained copy-paste snippets from wm8350 for this part - Cleanups for the DAPM_OUT_DRV_E event handler code. - delayed_works moved within their corresponding struct. The series has been generated on top of: git://opensource.wolfsonmicro.com/linux-2.6-asoc, for-3.2 branch + ASoC: omap-mcpdm/twl6040: Offset cancellation series. Side note: I have done this to better understand (while cleaning up the twl6040 driver) the requirements for the ramp code, and to study the possibility of adding support in the core for this (to handle the wm8350, and twl6040 in a generic way later). I'm still looking at the optimal implementation without ending up with too complicated code/structures... Regards, Peter --- Peter Ujfalusi (4): ASoC: twl6040: One workqueue should be enough ASoC: twl6040: correct loop counters for HS/HF ramp code ASoC: twl6040: Shift 2 identifies the HS output in out_drv_event ASoC: twl6040: Simplify code in out_drv_event for pending work check sound/soc/codecs/twl6040.c | 68 +++++++++++++------------------------------ 1 files changed, 21 insertions(+), 47 deletions(-) -- 1.7.6.1

[alsa-devel] alsa_aplay doesn't work on android on hdk7108
by Hou-xiang ZHU 29 Sep '11

29 Sep '11

Hello, I am trying to add alsa feature to Android on hdk7108 (which is sh4 architecture, not arm). Basically on non android linux platform ,i.e STLinux-2.4, the driver and alsa-libs and alsa-utils works with the following test command: --------------------------- #aplay -v -t raw -D hw:1,0 -c 2 -r 32000 -f S16_BE /32K_16Bit_Stereo.pcm" --------------------------- But when working on Android platform, because the alsa-lib/alsa-utils are different from STLinux-2.4, so we ask someone the two packages from a arm platform. and compilation ok. but during run alsa_aplay, the following error occurred: ----------------------------------- #/system/bin/alsa_aplay -v -t raw -D hw:1,0 -c 2 -r 32000 -f S16_BE /32K_16Bit_Stereo.pcm ALSA lib vendor/STMicroelectronics/hdk7108/alsa/alsa-lib/src/confmisc.c:137:(snd_config_get_bool) confmisc.c in func snd_config_get_bool line 137 Invalid type for nonblock ALSA lib vendor/STMicroelectronics/hdk7108/alsa/alsa-lib/src/pcm/pcm_hw.c:1417:(_snd_pcm_hw_open) Invalid type for subdevice aplay: main:656: in aplay.c func main line 656 audio open error: Invalid argument aplay/main.c in func main line 452 alsa-lib/src/pcm/pcm.c func snd_pcm_open line 2242 after call snd_config_update(), err=1 ---------------------------------- looks like alsa configuration issue. I noticed that on STLinux-2.4 platform, the alsa-libs is 1.0.21a and on android platform, it is 1.0.16, can this be a issue? or configuration file wrong or else? how to debug this? Thanks you very much! Houxiang

[alsa-devel] [PATCH] ASoC: tlv320dac33: Add guarding parentheses to macros
by Axel Lin 29 Sep '11

29 Sep '11

Put parentheses around macro argument uses. This avoids pitfalls for the programmer, where the argument expansion does not give the expected result, for example: SAMPLES_TO_US(substream->runtime->rate, dac33->uthr - DAC33_MODE7_MARGIN + 1); Signed-off-by: Axel Lin <axel.lin(a)gmail.com> --- sound/soc/codecs/tlv320dac33.c | 6 +++--- 1 files changed, 3 insertions(+), 3 deletions(-) diff --git a/sound/soc/codecs/tlv320dac33.c b/sound/soc/codecs/tlv320dac33.c index 243d177..389b1c2 100644 --- a/sound/soc/codecs/tlv320dac33.c +++ b/sound/soc/codecs/tlv320dac33.c @@ -55,13 +55,13 @@ #define BURST_BASEFREQ_HZ 49152000 #define SAMPLES_TO_US(rate, samples) \ - (1000000000 / ((rate * 1000) / samples)) + (1000000000 / (((rate) * 1000) / (samples))) #define US_TO_SAMPLES(rate, us) \ - (rate / (1000000 / (us < 1000000 ? us : 1000000))) + ((rate) / (1000000 / ((us) < 1000000 ?

[alsa-devel] [PATCH 1/6] ASoC: Remove unused "control_data" field of struct ak4671_priv
by Axel Lin 29 Sep '11

29 Sep '11

The control_data field is used to initialize the codec's control_data field, but since this is also done by the snd-soc-cache core, the redundant assignment can be removed and the field can be dropped.

[alsa-devel] [patch] sound: oss: use strlcpy() in sound_timer_init()
by Dan Carpenter 29 Sep '11

29 Sep '11

sound_timer.info.name is a 32 character buffer. This function only has one caller (in sound/oss/ad1848.c) and it passes as 128 character buffer as "name". I don't know if this is a problem in real life, and I doubt we're going to add more OSS drivers so it's unlikely to become an issue. But we may as well take care of it.
