[alsa-devel] ALSA initialization still seems to be too late?
by Adrian Bunk 23 Mar '07

23 Mar '07

The commit below from 2005 (sic) seems to be an example that workarounds often have quite a long lifetime. Can we get this sorted out properly for 2.6.22? TIA Adrian commit c7ac6b42ffba28c350cbcd48268f46689f6eb1cc Author: Linus Torvalds <torvalds(a)g5.osdl.org> Date: Wed Dec 21 14:52:32 2005 -0800 Initialize drivers/media/video/saa7134 late When compiled-in, make sure the sound system has initialized before these drivers do. Reported by Adrian Bunk <bunk(a)stusta.de> (The right fix would be to make the sound core use "subsys_initcall()" and thus initialize before all normal drivers, but this is the quick and limited safe fix for 2.6.15).

Hello; I am running into some trouble with writing out to the device, i get some sound and then i get the Write error. Heres the code fragment: if (-EAGAIN == (iErr = snd_pcm_writei(handle, pu8Frames, iSizPer))) continue; if (0 > iErr) { printf("Write error: %d,%s\n", iErr, snd_strerror(iErr)); Is the problem that my buffer (pointed to by pu8frames) isnt big enuf? or is this a different failure entirely. If so, what are the possibilities? tnx!

[alsa-devel] PCM -- no need to release params mem nor close handle?
by intellij 23 Mar '07

23 Mar '07

I am looking at PCM interface manual http://www.alsa-project.org/alsa-doc/alsa-lib/pcm.html It tells that there are an open and set_params functions but nothing about close(). Furthermore, the description of open() http://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m.html#g8340c7dc0… neither tells that. Ok, I have realized from the examples. However, even the examples demonstrate no params deallocation. You call the snd_pcm_hw_params_alloca(&hwparams) but never release the allocated memory. Why? Thank you.

Re: [alsa-devel] Réf. : Where is _snd_pcm defined?

Thank you for your answer. However, you information is not correct. I do not have the snd_pcm structure in the three copies of pcm.h I have in alsa-lib/include, arm-linux/alsa nor arm-linux/include. Peahaps, this is because my lib is slightly obsolete. Fortunately, today I have accidentally discovered the requested _snd_pcm structure in the alsa-lib/src/pcm/pcm_local.h. Excuse me for the fuss. BTW, we have fallen out of the mailing list. Forums are efficient only when there are many participants for two reasons: neighbors can provide more information and the same questions will be prevented from asking repeatedly. Do you think this case is different? > >Hello, > >If you get the alsa-driver sources, you can have everything you need (hope :-). >Note that in my typedefs.h, I don't have any _ at the beginin, so "struct snd_pcm" is in alsa-kernel/include/pcm.h. > >Regards, >JM > > >********************************* >This message and any attachments (the "message") are confidential and intended solely for the addressees.

[alsa-devel] Where is _snd_pcm defined?
by intellij 22 Mar '07

Hello, I have gone through all the source codes to wee the definition of snd_pcm_t and see that it is defined typedef struct _snd_pcm snd_pcm_t; But is has many fields inside! At least, name and fast_ops pointers should be there. I do not understand where are they hiding. Actually, I am an alsa user. However, the system occasionaly hangs on writing into the buffer (because the consumption stops). For this reason, I'm looking for the features for hacking the system. I have an idea of turning the printfs on/of in runtime by a shared flag. I could put the pointer to the flag into pcm, so that my application could modify it and the library functions would check it before printing the traces. Thank you.
