Hi,
it seems that it is quite required (based on current LKML
discussion) to keep the alsa-lib compatibility with old drivers. Please,
keep in mind that for example renaming of control names will break using
old 2.6 kernel with new alsa-lib.
The alsa-lib C code already checks for older drivers, but
the extended configuration (like 5.1, s/pdif devices) in most cases
changes a lot. We should add some runtime checks which driver version
is running in XXXXX.conf files and apply the old behaviour if required.
Any comments?
Jaroslav

Agreed. I proposed a similiar proposal sometime ago but got no
comments at that time ;)

How do you propose we solve this problem:
/usr/lib/mozilla-firefox/firefox-bin: relocation
error: /usr/lib/libalsatoss.so.0: symbol
snd_pcm_hw_params_set_rate_near, version ALSA_0.9.0rc4 not defined in
file libasound.so.2 with link time reference
My apps are compiled against alsa-lib 1.0.9 but I have 1.0.11-rc2
installed.

Hmm. It should work. The libasound.so.2 should have this symbol defined:
perex@tm8103:~/alsa/alsa-lib/src/.libs> nm libasound.so.2 | grep rate_near | grep rc4
00041460 T snd_pcm_hw_params_set_rate_near@@ALSA_0.9.0rc4
and the libalsatoss.0.0.0:
perex@tm8103:~/alsa/alsa-oss/alsa> nm .libs/libalsatoss.0.0.0 | grep rate_near
U snd_pcm_hw_params_set_rate_near@@ALSA_0.9.0rc4
Could you check it?

I got different output. But, I think the problem was I forgot to
install the newer alsa-oss.
$ nm /usr/lib/libasound.so.2.0.0 | grep rate_near
00044f63 t __old_snd_pcm_hw_params_set_rate_near
00040ff5 T __snd_pcm_hw_params_set_rate_near
00040ff5 W snd_pcm_hw_params_set_rate_near
$ nm /usr/lib/libalsatoss.so.0.0.0 | grep rate_near
U snd_pcm_hw_params_set_rate_near@@ALSA_0.9.0rc4

The libalsatoss library is fine, but alsa-lib was probably compiled
without versioned symbols (it's the default so I wonder why). Could you
retest with your distro?
