Right, got that. On the PWS600au it shows the same problems that Bob
describes! When I play it with aplay (through the es1887) I get the
last "pal" repeated at the end. When I play it with sox (also through
the es1887) I get the words "current event" repeated at the end.
Playing through the CM8738 also repeats the words "current event" at the
end when playing with sox. But using aplay through the CM8738 only
results in silence and aplay hangs. A ctrl-c successfully breaks it.
Lovely, so different problem between you and Bob. When you (either of you)
have some time for it again, could you try:
$ sox asskickd.wav -w -t alsa hw
$ sox asskickd.wav -w -r 44100 -t alsa hw
$ sox asskickd.wav -w -r 44100 -c 2 -t alsa hw
and report if things start working? First transforms into 16-bit, second
16-bit and 44100 rate, third 16-bit, 44100 rate, stereo.
I suspect you are right - the symptoms I have observed (complete system
crashes) are separate from what Bob observes. One question I have is
what is different about Bob's set up that enables the sound to work with
mmap?
Not a clue. Takashi -- is it possible that Bob wasn't using mmap to being
with if he didn't do anything specific to not do so?
And perhaps you guys have firmware settable options that touch that area of
coherent DMA? Maybe even a specific chipset bug on his machine? No idea how
different/similar your machines are...
On the XP1000 (which has an unmodified kernel 2.6.24.3) I managed to
play the sound file once with aplay through the es1887 (and it repeated
"pal" at the end). Then I tried using sox and complete silence
resulted. No, it's just playing back at the wrong rate - everything
is sounding slow and extremely flat - the silence is just the artefact
of a little bit of silence at the start of the file being played at far
too a slow sample rate. Even other client programs are affected - mocp
is playing back music at a horrendously slow sample rate. Yuk. Hopefully
a rmmod es1887 might fix that - but I can't test it to I send this
message and shut down X.
Anyway I really must start marking that pile of assignments I told the
students that I would have done by tomorrow. Further testing will have
to wait to later this week.
No rush. Thanks for the current amount of testing already.
Rene.
