[alsa-devel] No sound from laptop speakers (Resolved)
by Manilal K M 10 Dec '08

10 Dec '08

Hello everybody, Recently I have installed Fedora 10 on my Compaq CQ45 laptop. But unfortunately there was no sound from the laptop speakers even though the headphones worked perfectly. I did some google search but it didn't helped. Later, on a discussion at #alsa(freenode.net), one of the IRC member(nickname: copper) gave some clue and finally found that I have to upgrade the alsa driver and pass the model id(dell-m4-1) as a parameter in modprobe.conf. Here are the results generated by alsa-info.sh before and after upgrading to the latest alsa(1.0.18a). http://www.alsa-project.org/db/?f=9a29eac2731b3de1c17183d6c43aac3fa11942c9 http://www.alsa-project.org/db/?f=9a29eac2731b3de1c17183d6c43aac3fa11942c9 The option I have passed to /etc/modprobe.conf/alsa-base is : options snd-hda-intel model=dell-m4-1 After reboot, I was able to hear sound from laptop speakers. -- Manilal K M : മണിലാല്‍ കെ എം. http://libregeek.blogspot.com

[alsa-devel] [PATCH 0/9] ASoC: TWL4030: DAPM implementation for outputs (playback) - try3
by Peter Ujfalusi 09 Dec '08

09 Dec '08

Hello, The whole series again, altrough 1 and 2 has been accepted already. This series of patches (try3) adds DAPM implementation for all outputs found on TWL. The design allows one to configure all outputs independently from each other, since the internal routing of TWL actually treats them individually. The pre-DAC routings can be configured in the board specific files of needed. I have sent a patch which has added this to the codec driver. Based on the output routing selections all the corresponding DAC and analog PGA on the chain will be powered on. Remove the Headset output gain modifications from the twl4030_power_up and twl4030_power_down function, since they are not needed. Changes since try1 (comments addressed): - Removed the " Switch" from the option texts and also from the intercon. --- Peter Ujfalusi (9): ASoC: TWL4030: Correct DAPM_DAC with power control ASoC: TWL4030: Add Analog PGA control switch to DAPM ASoC: TWL4030: Add DAPM event handler for output MUX selection ASoC: TWL4030: DAPM mapping of the Earpiece output ASoC: TWL4030: DAPM mapping of the PreDriv outputs ASoC: TWL4030: DAPM mapping of the Headset outputs ASoC: TWL4030: DAPM mapping of the Carkit outputs ASoC: TWL4030: DAPM mapping of the Handsfree outputs ASoC: TWL4030: Do not alter the Headset output volume on power-up/down sound/soc/codecs/twl4030.c | 263 +++++++++++++++++++++++++++++++++++++++++--- 1 files changed, 248 insertions(+), 15 deletions(-)

[alsa-devel] ASoC: hook for codec control updates and clock controls
by Daniel Mack 08 Dec '08

08 Dec '08

Hi, Codecs like the tlv320aic3x family have soft volume controls to smoothly drive up and down mixer elements in order to prevent clicks and pops. In fact, most of the controls on this chip are implemented as such. For the mixers to work, however, the I2S input clock is needed which is currently only true when the DAC/ACD elements are active but not when the chip is just operating as an analog mixer. To allow this functionality, the I2S clock must be present for a short period after each volume control update to the codec and disabled again after some milliseconds. It should, however, not be enabled if it's already running and of course, it must not be disabled if the ADC/DAC is still running. Adding a hook to struct snd_soc_codec which is called from snd_soc_update_bits() isn't a big deal, but the problem is the abstraction layers in this case - for good reasons, the cpu_dai is not accessible from the codec dai. Or did I miss a link? Is there a sane way to address this problem? Thanks and best regards, Daniel

Hi, Feel free to comment on the included patch. I had to add it because aseqnet would not link without -lintl. -- Best regards, Hans-Christian Egtvedt

[alsa-devel] [patch] alsa-utils check if __USE_BSD is defined before compiling "BSD functions"
by Hans-Christian Egtvedt 08 Dec '08

08 Dec '08

Hi, Another bug/issue I tripped over when compiling alsa-utils in an environment using uClibc to supply the C library functions. Here I have enabled some old BSD style functions. The attached patch will honor them if they are enabled. Without this patch I get a redefined error during compile. -- Best regards, Hans-Christian Egtvedt
