[parisc-linux] [PATCH] harmony audio driver

[parisc-linux] [PATCH] harmony audio driver

[-- Attachment #1: Type: text/plain, Size: 625 bytes --]

hi,

I implemented SNDCTL_DSP_CHANNELS in harmony.c, which is used to query
or set the number of sound channels. This allows some sound apps to run
that used to quit with an error.

I also added SNDCTL_DSP_SYNC that only returns 0 at the moment. This is
needed since neary all sound apps call this during initialization.

The sound driver however is still broken, the only program I know that
works 100% correctly is xmms. Maybe I will do some bug fixing later if
anyone is interested.

PS: is there a working patch to get keyboard running again on 712, it is
broken for months (since kernels after 2.4.0-paXX)

bye

I just found out that mpg123 runs and sounds perfectly now(now you should
merge the patch in ;-) )

PS: to compile mpg123 you can type make linux-ppc, it works.

I think I fixed this last week in the debian-source (which should be upstream now),
so "make linux-hppa" should work too.
