I am trying to get the Emu10k1x chip supported in alsa. Anyone willing
to give me a hand, please email me. I've got a few register dumps and I
am trying to get it working.
Now for the question, I tried to add a snd_printk() call to the
pci/emu10k1/io.c ptr_write function, but it causes the system to hang.
Is there any alternative to that?
Thanks,
Francisco

it already sounds like you're accessing a wrong register...

I removed all the writes and left only mine and I can now trace the PTR
writes. I have not been able to get interrupts working, so it seems like
alsa keeps calling the PCM trigger function with a start and then
followed by a stop. And the process goes on.
Any way I can avoid this or change how things work internally a bit?

this is likely buffer underrun.
i guess the pointer callback doesn't return the correct value, and the
ALSA PCM core thought it's out of sync. try to put printk this
value.
the OSS emulation resets stop/start automatically, so it's not
avaoidable. but ALSA native apps do it by themselves, so it's the
application thing. you can disable the behabior in the application
itself (see aplay.c and xrun).

Here are few register dumps I took with the Emu10k1 driver modified to
do no writes and an added proc entry to dump the registers.
The first is the state the first time I loaded it (regs-before.txt). The
second is the state after loading/unloading the OSS eval module. The
third is after playing an MP3 with the OSS module.
I still had no luck in getting anything playing, so any insights are
appreciated.

I seem to be getting closer now. Still no sound, but XMMS is not running
crazy anymore. Now it hangs after two seconds. Here are some of the

Hi everybody,
Just wanted to share the status of the Emu10k1x driver (Dell SB Live!
Value). I've finally got PCM playback working at 48000khz and a 32Kb
buffer. I haven't tried too much more than this which is hard because of
lack of specs for the card.
I am doing some clean up and I hope to have a first pass of the drive
submitted soon.
By the way, I've also added support for the joystick port on the card.
This could have been done by simply adding the PCI ID into the
drivers/char/joystick/emu10k1-gp.c driver in the linux kernel. Any
suggestions or preferences of whether this should be changed in the
kernel driver or in the alsa driver itself like I have at the moment?

yes, please. we can review the problem.

no, it's an independent driver. please submit the patch to the
author of the emu10k1-gp driver (Vojtech).
