[alsa-devel] Writing a new plugin for ALSA
by Nobin Mathew 10 Jul '07

10 Jul '07

Hi, I am trying to write a new ALSA plugin, like dmix. My intend is to give priority to streams, i will not do up sample and down sample as we do in the case of dmix. If we do up sample and down sample then I think it will take lot of cpu. In my case I have three streams audio, bluetooth sco and Navigation sound data. priority is audio < sco < Nav audio rate is 44100hz, sco rate is 8000hz when sco is up audio should pause playback and audio should continue when sco is finished. I dont want to do software mixing. Thats why I am trying to write this new plugin. Assume that audio is active first, then sco comes to active state. So what i will do is in the library i will put audio app in sleep(), and re-configure the pcm for sco. Once sco is finished i will re-configure pcm for audio again like wise. so my question is there any api in the alsa-lib to take a copy of pcm structures, so when audio comes back gain i can use these saved pcm conf to that. Is there any api in the alsa-lib to reset the pcm structure to initialized state, means state just after open. Thanks Nobin Mathew

Hi Clemens, Can you push this for 2.6.23 ? Or is there anything else missing in the patch ?

[alsa-devel] Unable to find an usable access for 'default'
by Timur Tabi 10 Jul '07

10 Jul '07

I'm developing a new ASOC driver, and I get this error message: ALSA lib pcm_plug.c:729:(snd_pcm_plug_hw_refine_schange) Unable to find an usable access for 'default' Can someone tell me what this means? FYI, I'm in the early stages of testing my driver, and before I started I knew nothing about ALSA. This is on an embedded system, so I don't know if my ALSA installation is correct. Am I missing some kind of configuration file? -- Timur Tabi Linux Kernel Developer @ Freescale

[alsa-devel] Intel hda ICH7 not worked anymore after using wine
by Xavi de Blas 09 Jul '07

09 Jul '07

Hello, I installed Wine on my Ubuntu Feisty on IBM-lenovo X60s, and after reboot, sound never worked again. I tried to activate and to hide modem on the bios. I tried to stop machine, take off battery, wait 10s, put battery again, and boot without the power cable connected... and i tried lots of things from ubuntuforums. I reinstalled feisty and sound doesn't work. I used alsa-info.sh script, here is the result: http://pastebin.ca/610317 Should the new kernel 2.6.22 help me? http://kernelnewbies.org/Linux_2_6_22#head-0d133cda430e5d18f1c72dd3cfaa6a92… Thanks

Hi guys, I am write a codec driver under asoc frame work for ad1980 by study the sample driver wm9712.c. I find there are some control item likes "out3 switch" to control 16h:15. There are also some widget item likes "out 3 PGA" to control 24:5. How can I determine a register bit should be a control item or widget item? Thanks ahead. -Roy
