Hello, thanks for including fixes for my previous problems
loading alsa modules into linux-2.2.25. Unfortunately, a new
problem appeared in alsa-driver-1.0.1. It compiles happily,
but will not load:
/lib/modules/2.2.25/misc/snd-page-alloc.o:
unresolved symbol snd_wrapper_request_region
I suspect the cause is a recent change to the file
alsa-driver-1.0.1/acore/pci_compat_22.c
I managed to load the modules by changing acore/pci_compat_22.c:
356c356
< snd_wrapper_request_region(pci_resource_start(pdev, bar),
---
> request_region(pci_resource_start(pdev, bar),
but confess to not fully understand the code, so please check this.
Now a longer standing problem. I have not been able to use alsa since
the alsa-lib API changed, because I still get bad data passed by
pcm.c:6442 snd_pcm_hw_params_set_period_time_near(),
to
pcm.c:3782 __snd_pcm_hw_params_set_period_time_near(),
on its way to
pcm_params.c:786 snd_pcm_hw_param_set_near().
The argument to these functions called "val" is being dereferenced
once too often. Possibly by the macro
pcm.c:6424 __P_OLD_NEAR1
I note that no-one else is reporting this problem, and many people
seem to be able to run programs like aplay and alsaplayer without
getting nonsense like this:
aplay /home/ted/Sound/Data/drum6.wav
Playing WAVE '/home/ted/Sound/Data/drum6.wav' : Signed 16 bit Little Endian, Rate 8000

aplay: set_params:875: Unable to install hw params:

SAMPLE_BITS: 16

PERIOD_TIME: (341333 341334) <---****

BUFFER_TIME: (341333 341334)
BUFFER_SIZE: 46041077
BUFFER_BYTES: 184164308
TICK_TIME: 10000
I can only assume it to be related to my particular setup.
I'm using gcc-2.95.3 glibc-2.1.3 ld.so-1.9.9 libtool-1.5
modutils-2.3.17 binutils-2.10 linux-2.2.25. What else?
I configured alsa-lib with
./configure --prefix=/usr --with-versioned=no --with-debug=yes \
CFLAGS="-g -O2" LDFLAGS="-g -O2"
and aplay with
./configure --prefix=/usr \
CFLAGS="-g -O2" LDFLAGS="-g -O2"
I've double checked that there are no old headers or libraries
lying around from earlier versions of alsa. I tried deleting
the dynamic libasound.* and rebuilding aplay against a static
libasound, but the problem wont go away.
Suggestions?
Ted.
