[alsa-devel] [PATCH RFC 0/3] WM97xx AC97 GPIO support
by Manuel Lauss 16 Jun '10

16 Jun '10

Here's 3 patches which implement simple AC97 GPIO support to the WM97xx touch drivers and the Alchemy (au1x) AC97 ASoC implementation. Tested on Au1200 hardware with a WM9712 codec: According to Mark Brown the WM9712 only sets GPIOs when data is sent through slot 12, which prompted me to implement this. Thanks, Manuel Lauss Manuel Lauss (3): sound: ac97: Add GPIO manipulation hooks input: wm97xx: set GPIOs with AC97 GPIO busops if implemented sound: asoc: au1x: implement AC97 GPIO access drivers/input/touchscreen/wm97xx-core.c | 5 +++- include/sound/ac97_codec.h | 2 + sound/soc/au1x/psc-ac97.c | 39 +++++++++++++++++++++++++++++- sound/soc/au1x/psc.h | 2 + 4 files changed, 45 insertions(+), 3 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe alsa-devel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

A simple depends on I2C will suffice for this purpose just fine.

[alsa-devel] snd_pcm_wait won't return
by Dennis Borgmann 16 Jun '10

16 Jun '10

Dear alsa-devel list! I already posted this on alsa-users, but this list doesn't seem to be that crowded so I will give it a try in here... I am using the alsa-lib in one of my projects and within this project, there is a call for snd_pcm_wait() on a machine, that plays sound. The call itself looks like this: snd_pcm_wait( pcm_handle, 1000 ); A few steps before, I had the timeout set to unlimited (-1), which sometimes did not return at all. Now, it sometimes returns after the timeout, but in result I cannot write anything to the soundcard anymore. This error is reproducable if there are many underruns in a row. Since this program runs in a network environment and receives its data from a datastream, I sometimes cannot avoid those underruns. So, what could be the error, that leads to alsa not responding anymore? I can only revitalize the system after such an error by rebooting the whole system (well, at least I did not find another solution like snd_pcm_prepare or snd_pcm_recover). Which additional informations do you need? What is there, that I can provide in addition? Could this be an alsa-bug? Kind regards, Dennis

No, while the two boards in mainline currently may need I2C obviously other board designs with other control interfaces are possible so it should be on the individual boards.
