[alsa-devel] Samsung P50 Heaphone Jack-Sense not working with latest ALSA
by Martin Egge 29 Jun '09

29 Jun '09

Hi, last year Takashi did help me to get the digital output and the internal/external mic up and running on my Samsung P50 notebook with an integrated Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller. Some time ago I switched from Ubuntu 7.10 to 8.10 and a new problem with the soundcard occurred. The Headphone/Line-Out Jack-Sense is not working. When I plug in my Headphones the internal speakers of the notebook aren't switched off. I've ignored that problem for a long time but now I'm willing to change this. I've already upgraded my system to ALSA 1.0.20 with a script provided in the Ubuntu Forums [2]. I've used the build-in support for the latest snapshots provided at [3] of the script. But the problem still exists. Can anyone (perhaps Takashi again) help me? You can find all ALSA related information about my system at [4].

[alsa-devel] cmi8330: revert comments about AD1848 back
by Ondrej Zary 29 Jun '09

29 Jun '09

In ALSA 1.0.20, the comments were changed to say CMI8330 instead of AD1848. The CMI8330 chip includes two codecs - AD1848 and SB16, so the comments were correct and are misleading now.

Not supported. Some DSP code would be required, which isn't open yet. thanks, Takashi

There is no generic way. The assignment order is usually static and unchanged for such PCI devices. (Or, you can change the slot later via sysfs, if any.) In general, you shouldn't stick with the assignment order but rather use the id string to each device. Takashi

You can specify index option, e.g. index=2,1,0. Takashi

Re: [alsa-devel] Should my Creative X-fi card be loading the snd-hda-intel module

>> Shouldn't it be loading snd-hda-codec-ca0110 instead? > >snd-hda-codec-ca0110 is a slave module loaded by snd-hda-intel. > >Takashi The problem is, my Creative X-fi isn't being recognized any more, even though the modules are there and have been loaded. My onboard card is an hda-intel. And my utilities and programs don't find the Creative card. They only find the onboard card. I have added asoundconf to my alsa-utils, and asoundconf list shows only: Intel system (my usb card) winecfg shows the same. My goal is to get the card running again under wine. Susan

[alsa-devel] [PATCH] ASoC: TWL4030: Add EXT_MUTE gpio to reduce pop-noise effect
by Jorge Eduardo Candelaria 27 Jun '09

27 Jun '09

According to TRM, an external FET controlled by a 1.8V output signal can be used to reduce the pop-noise heard when the audio amplifier is switched on. The signal is controlled by a gpio pin and should be defined in the machine driver. However, the codec driver takes care of enabling and disabling this output during the headset pop attenuation sequence. If the board does not have an EXT_MUTE, then the machine driver should set the value of ext_mute_gpio to -EINVAL through ramp delay setup data, to bypass execution of the code that manages the gpio line. Also add a delay to let VMID settle in ramp up sequence.
