A few minor fixes to the emu10k1x driver. Also, it would be nice to update the soundcards page to list it as supported (mention that only PCM playback is currently supported).
I will try to test a few more things before 1.0.5 gets final, I hope.

are you sure this change is correct?
in the current code, the period size is always bound to
(buffer_size / 2) (because periods_min = periods_max = 2).
so you don't have to limit period_bytes or period_size.

hmm, it looks redundant.
the second line will override the setting of the first line.
i guess you wanted like the following?
snd_emu10k1x_intr_enable(chip,
(INTE_CH_0_LOOP|INTE_CH_0_HALF_LOOP)<<1 |
(INTE_CH_0_LOOP|INTE_CH_0_HALF_LOOP)<<2);

well, it should be same casually in your setting...

yes, you're right. i've overseen it.
still it would be better to call once with all or'ed bits.
i'll change the code on CVS, which will go into 1.0.5-rc2.
BTW, at the next time, please post the patch with unified diff style
(diff -u)?
thanks,
Takashi

Please commit to CVS with the following changes:
- added support for more periods (up to 512 for playback)
- formatting clean up
