by Sean Thayne 26 Apr '08

Hi Everybody, I was talking with some users in the irc channel in the free node, and was hoping to find a way to get the information about weither or not anything was plugged into the sound card, I've seen this feature with windows vista. I search thru a bunch of documentation sites and also scanned the /proc & /sys to no avail... Thanks, Sean T

[alsa-devel] Status of X-Fi support in ALSA?
by James Pearson 25 Apr '08

25 Apr '08

Out of general interest, what is the current status of X-Fi support? On a related note, I notice that Creative have recently released the 2nd beta of their closed source drivers: <http://connect.creativelabs.com/opensource/Wiki/SoundCard%20Support.aspx> Thanks James Pearson

[alsa-devel] [RFC] ucb1400 touchscreen, irq auto probing and ac97 with its private field
by Sebastian Siewior 25 Apr '08

25 Apr '08

Hello, I've sent a RFC to the alsa mailing list [1] about adding an extra field in order to pass the IRQ from the AC97 driver to the ucb1400 driver. The result was: - William Pitcock recommended to hack up the ucb1400 driver and save the irq there. The result is [2]. What I don't like very much is the global variable and the fact that has to be done for every platform. - Mark Brown has the same problem with his wm97xx driver [3]. and while browsing a dead list archive of linux-input I noticed that a guy named Peter Ma has the same problem on his AVR32 [4]. I haven't heard anything from the ALSA Maintainer but according to git he didn't put a sing-of-by line since Thu Jan 31 17:40:18 2008 +0100 so maybe he is sleeping. That's why I've add Takashi Iwai since he seems to be in charge some how. Now I'm curious what solution the people here prefer: - adding a private field [1] (my favorite) - hacking up the ucb1400 [2] (doesn't solve [3] and needs addition code to solve [4]). - something totally different what did not come to my attention yet.

[alsa-devel] [PATCH 1/3] asoc tlv320aic3x: revisit clock setup
by Daniel Mack 25 Apr '08

25 Apr '08

This patch cleans up the clocking setup for aic3x codecs. It drops the dividers table and determines the PLL control values programatically. Under certain conditions, the PLL is disabled entirely which could save some power. Signed-off-by: Daniel Mack <daniel(a)caiaq.de>

[alsa-devel] [PATCH 2/3] asoc tlv320aic3x: add GPIO support
by Daniel Mack 25 Apr '08

25 Apr '08

This patch adds support for AIC3x GPIO lines. They can be configured for many possible functions as well as be driven manually. I also introduced i2c read functionality since the GPIO state register has to be read from hardware every time and can not be served from cache. Signed-off-by: Daniel Mack <daniel(a)caiaq.de>

[alsa-devel] asoc tsc210x

25 Apr '08

Hello all, I'm assessing TSC2100 codec on an embdedded system. Any intentions on implementing an ASoC codec driver for TSC210x family? Could the multi-function nature of the chip raise some issues with ASoC framework? -Jukka
