[parisc-linux] 0.9.3 Audio on C110

[parisc-linux] 0.9.3 Audio on C110

[Michael Audette]

Hello,

First off I would like to give Kudos to everyone who worked on this project.
I cant believe the C110 is actually doing something useful again (and I
don't have to deal with HP's version of POSIX).  I cant believe that
everything including X and gnome, KDE etc are all working rather flawlessly!

I do have one problem still.  I am at a loss for the Audio.  It would appear
by looking back in the threads that the audio is working on this model
9000/C110.  But I don't know how to go about getting it working.  Do I need
to rebuild the kernel?  Is there a module that can be loaded for it?  Or are
my /dev screwed up for audio/dsp?

				-Thanks!
				  Mike

Works fine for me: only playback though - no recording :(

monk:~# ls -l /dev/dsp
crw-rw----    1 root     audio     14,   3 Nov 15  2001 /dev/dsp

The driver is called "harmony" - I have mine hard compiled into the kernel.

Does anybody knows if it is specific to C110/C100 (Raven) or is it the 
case for others?
Personnaly, I have recording support on my B132 and 712.

"harmony" is integrated into the LASI chip.
AFAICT, all the workstations vintage 712 to C360 have LASI.

Hi palinuxer,

This reminds me of something I wanted to ask for a long time:

It seems that the harmony mixer is not perfectly supported;
Volume doesn't work, and there are just two things I can change,
IGain and OGain (latter effects the Output volume).
There is not even a way to change the balance etc.
Moreover most applications expect at least "volume" to be working,
so this is kind of annoying. Despite this it's working flawlessly!

So to the question: is there any work planned in improving harmony
support (in the near future) ? E.g. an enhanced mixer support and
support for recording?

greetings max

Dear Max,

i cannot speak to the mixer and gain issues, but i can offer something
with regard to recording:  adding lines:

	case SNDCTL_DSP_SYNC:
	return 0;

to the ioctl swith statment in drivers/sound/harmony.c (line 727 or there
abouts) will allow you to use sox to record (i have been able to
succesfully record using sox after adding this change).

best regards,
james w. mcclain

FYI, I've added this patch to the 2.4.18-pa40 CVS kernel.

Hi,

If nobody is already on it, I will plan to spend a lot of time on this 
mixer after my graduation next week.
If someone has feedback about strange behaviour like the one explained 
above please do not hesitate to contact me.

Regards,
Matthieu

[parisc-linux] Audio on J5k

[Jeremy Drake]

Are there any plans to support the AD whatever that is in the J5k?  Is 
there documentation available?

yes and yes.

Randolph Chung (tausq@debian.org) had started hacking on this driver
since he also has a C3000. He hasn't had time to get it working
and should probably just post his "patch" to ftp.p-l.org in case
someone else wants to (try to) make it work.

I've posted documentation in April on this chip:
	gsyprf10.external.hp.com:/pub/grundler/AD1889.pdf

(from memory, it's there:
-r--r--r--    1 grundler users      124255 Apr 24 21:28 AD1889.pdf
)

i've been working on it, quite slowly. the documentation available is a
bit scant.... the same chip is in the c3k.
