To install latest alsa plugins in ti sdk 8

Hi,

I will ask the SW team to look at this.

Dear Kemal,

Could you please provide any inputs w.rt. the below queries

1. Could you please let me know, firstly where can I find alsa libraries in ti sdk 8 rootfs with what names???

2. What is the version of this alsa libraries??? does this alsa libraries support all alsa plugins like dshare, dmix jack etc., how can I confirm this that it exists in the ti sdk 8 rootfs??

3. Mainly Does this alsa plugins support Jack plugin also ?? or it needs to be explicitly re compiled, if it is recompiled with the earlier procedure provided in the previous link () how can i confirm that it is compiled with jack plugin

Could you please kindly clarify this??

So that I can establish my own build environment as you suggested above

Kindly do the needful as early as possible

Pls let me know if you require any other details from my side

Many Thanks in advance

/usr/lib/libasound.la
/usr/lib/libasound.so
/usr/lib/alsa-lib/smixer/smixer-ac97.la
/usr/lib/alsa-lib/smixer/smixer-ac97.so
/usr/lib/alsa-lib/smixer/smixer-hda.la

The version of the library is 1.0.27.2-r0. The library should supports every plug-in that is designed to run on it. You can refer to the software manifest to check the present plug-ins in the SDK.

I have built the jack plug-in and attached the *.ipk in this reply.

Hello Srini,

The dependency packages needs to be installed firstly but in this case you can skip them with the --nodeps argument.

Best regards,
Kemal

Dear Kemal,

Thanks a lot for your quick responses,

Could you please provide the full command, to install the above ipk's, as this is the first time am using opkg, am not still sure whether opkg can be used for installing the above ipk's 

1. Could you please provide full command for installing the above ipk's in ti sdk 8, & Could you please provide the full path & names of the alsa jack plugin libraries where it gets installed

2. Sorry to ask you again, could you please let me know whether the jack plugin's ipk's which you had cross_Compiled are asla jack plugin's  only right???

Because now am planning to use plugins type jack in my asound.conf & am going to try with it

Kindly do the needful as early as possible

Many Thanks once again for your prompt responses

You can install all the ipks by this command: opkg install --nodeps *.ipk I have no information about where else the alsa libraries can be located except /usr/lib/ and about their other known names or code-names.

Thanks a lot Kemal for your support w.r.t this thread it was really helpful

Hello Srini,

At first glance, it seems like a missing library issue. Is this file /usr/lib/alsa-lib/libasound_module_pcm_jack.so available in your system?

Best regards,
Kemal

Yes Dear Kemal,

 Am still facing this issue from many days it is still open for me, could you please help me out in resolving this issue as early as possible

Could you please retry from your end & let me know 

Am facing the below error after I configure in jack in asound.conf as shown below, I have 

root@lifeline:/# vi etc/asound.conf

Many Many Thanks in advance Kemal,

Dear Kemal,

I have posted the same query to alsa community

That pkg-config does not know about "alsa". Apparently, TI's SDK did

not install alsa.pc together with the rest of alsa-lib.

Report this bug to TI.

As a workaround, try cross-compiling alsa-lib yourself.

And Now I have cross_compiled the alsa-lib on my own in ti sdk 8 but still am unable to find the libasound_module_pcm_jack.so, could you please help me out, using this pkgconfig how it can be used to cross_complie alsa_plugins & get the library

srinivasan@tata-HP-Elite-7100-Microtower-PC:~/alsa_libraries/alsa-lib-1.0.26/binaries/lib/pkgconfig$ ls

alsa.pc
srinivasan@tata-HP-Elite-7100-Microtower-PC:~/alsa_libraries/alsa-lib-1.0.26/binaries/lib/pkgconfig$ cd ..

Could you please kindly do the needful as early as possible, as you are aware am stuck with this issue from many days

Many Thanks in advance

Dear Kemal,

Greatly appreciate for your prompt effort & your support

I will definitely try & get back to you on this..

Many Thanks

Dear Kemal,

Extremely sorry for late updates as I was held up in other activites, after installing I have verified as below am seeing the below error with above asound.conf configuration in etc/asound.conf, could you please try from your starter kit & let me know whether this works for you..

root@lifeline:/# aplay -D pcm.jack TangoForTajMusic11.wav
FATAL: cannot locate cpu MHz in /proc/cpuinfo

Kindly do the needful as early as possible

Many Thanks in advance Kemal for your prompt responses once again & would really appreciate it

Thanks a lot for your Prompt responses Kemal,

Am planning to apply the below patch to make the jack work on newer kernel versions.

 github.com/.../d425d8035b761b4a362c538c41eca874ff4995f0 

As am unable to find the file to apply this patch in the linux kernel, where can I find this file?? to apply the patch, Is there any separate source code package , where I can apply this patch??

If there is a source code , could you please let me know how this can be cross_compiled & get the binaries/libraries installed in the rootfs or somewhere else??

Kindly do the needful as early as possible

Once again really appreciate for your prompt responses

Dear Kemal,

Once Many Thanks a lot for your support w.r.t this thread,

And I have seen that the below patch is already been reverted in the kernel which ever am using (ti sdk 8 BSP's ie., linux kernel 3.14),

Also could you please provide the jack source code links compatible with our ti sdk 8 BSP's, where I can apply the above patch & how this needs to be cross_compiled & installed in the rootfs

Kindly do the needful as early as possible Kemal as am stuck in this from long time

Many Thanks in advance again

Dear Kemal,

Extremely sorry to push you hard, could you please provide any inputs w.r.t the above query,

Dear Kemal,

Thanks a lot for your prompt responses

Are these warnings still present if you run the server with the -r argument?

jackd -r -d alsa &

Many Thanks a lot Kemal, that worked.. Greatly appreciate your support w.r.t this thread

But one issue is that when I try to play a 8Khz 16 bit mono wav file, I see the song is not completely being played, I hope that audio samples are getting dropped,

Can you please compare any one wav file which is of 8Khz 16 bit mono wav file by playing it your PC & your atarter kit using this jack plugin

Many Many Thanks w.r.t your prompt support8khz_16bit_mono.zip

Many Thanks a lot for your quick responses Kemal,

Fine no probs will try to keep posted in jack mailing lists,

Even I will try to debug the issue, Could you please let me know the verison of the jack plugins & the source code path being used in this thread & how to compile the jack plugins, please let me know with detailed steps ie., how to sync the source code & the path of the libraries needs to be copied to the rootfs & the commands used for compilation

Many Thanks in advance

Many Many Thanks a lot Kemal will try this definitely and will keep posted if face any issues in the build execution

Sure.
