i will have a slightly longer patch that includes this, later
today. also included will be a "no_mixer" option for the hdsp9652.

Paul,
   Is this envisioned an option in modules.conf, or a compile time option?

   Also, while I have your attention, can you clarify whether the RME
Hammerfall 9652 and 9636 have mixers? I made one of my 9636 machines into
dual boot last evening and then found alsamixer didn't work. I assume that
means the 9636 has no mixer, or is this a bug I should be reporting
somewhere?

Thanks,
Mark

Thanks for the info.

So then the only way to set volume levels on a DIGI9652 or DIGI9636 when
using Alsa is either in the application, or using some form of a script
like:

#!/bin/bash

for i in $(seq 1 26);do
amixer -c 0 sset 'Chn',$i 85%
done

Thanks,
Mark

only in the application. there is *no* mixer, nothing for ALSA to
control. whatever is written to the PCM data buffer is what comes out
of the hardware.

Paul,
   Did this driver & no_mixer option get into Alsa 0.9.6?

haven't submitted them yet. i've been too busy rebuilding my systems,
recabling the studio and dealing with a nasty buyer of my old
house. this week, for sure.

Thanks for the answer.

This is probably a silly question, but have you tested this driver and
option with an HDSP 9652 card at your site?

The current driver in the Alsa 0.9.6 release doesn't work very well for me:

1) Mono wave files work using aplay work fine.
2) Stereo wave files using aplay crash Alsa requiring a reboot.
3) Mono sound for games (presumably OSS emulation) seem to work.
4) aplaplayer (straight or using Jack) produces audio 1 out of 20 times I
use it, and then only for about a second or two.
5) 1 out of 10 times starting an application (games mostly) that uses sound
results in a process called 'ksoftirq_CPU0' using 70% of the CPU cycles and
the machine becoming very, very slow. A reboot is required.

I updated Alsa on Sunday via Portage under Gentoo.

As has been the case for quite a long time, the picture isn't very pretty.
Wondering if you're seeing anything like this?

Thanks,
Mark

i haven't used the hdsp9652 very much, and i certainly don't ever use
it with aplay. i don't use aplay for anything, really. i've used it
for periods of time with ardour+JACK, but i am mostly using the
hdsp+digiface that is present as well.

as a side, i must note that i have a bad feeling about ALSA on SMP
systems right now as well. running JACK with SCHED_FIFO seems to be
relatively capable of inducing system lockups at the moment. without
SCHED_FIFO, it seems OK. this is running the Planet 2.4.21 kernel on a
dual PII.

I understand. Thanks.

I only have used aplay for test purposes, and really would like to request
that you test both mono and stereo wave files using  aplay just to see if
you have the same problems I do. Thanks.

Unfortunately I cannot do any of this anymore as the current HDSP 9652
driver just doesn't work for me at all.

Thanks for the info though.

Mark

Re: Trivial hdsp.c patch to support rev 50 cards

[Dan Nyborg]

this message is originally from monday... i didn't realize when i replied to
the thread that i wasn't replying to alsa-devel, no wonder it didn't show up
on the list :P     sorry for the duplicate, paul.

********************************************
hello,

i modified hdsp.c to support my rev. 50 card last week (the trivial way), and 
have been experimenting with it for the past three days. everything seems to 
work - midi, spdif lock... - i even downloaded Charbonnel's mixer app, and it 
works great! i use a multiface.

however, when i try to play something with alsaplayer or aplay, my system 
freezes after 2 sec to 2 min of playback... sometimes i can get through a 
whole file, sometimes only partial, but an eventual lock-up is inevitable. i 
have not tried sending anything other than stereo, 44100kHz, 16bit files.

has anyone seen such behavior with this driver?

i am assuming it may have something to do with my setup: linux 2.4.20, alsa 
0.9.5 (with trivial patch to hdsp.c), devfs, recent multiface/pci card with 
rev. 50 firmware.

there's atleast one other person with the same hammerfall set who will be 
trying it out in linux later this week...

any comments appreciated,

dan.

Dan,
   I'm using a 'similar' driver from Thomas, but not the identical driver,
and with the HDSP 9652, not the MultiFace. Using aplay and MONO wave files
I'm fine. Using anything in stereo results in all sorts of problems,
including hard locks or at the minimum no further sound. Only a reboot fixes
this for me.

   Could you try a mono file and see what results you get?

   alsaplayer sometimes works for me. For about 30 seconds I'll get sound,
and then the sound stops and doesn't work until a reboot.

- Mark

Re: Trivial hdsp.c patch to support rev 50 cards

[Dan Nyborg]

hello,

tried playback of a mono file, to the same ends. yesterday in one instance, i
got around 45min of stereo playback before  a lock up.

also experienced a lock up in ardour yesterday, monitoring a single channel
and outputing it on another channel.

haven't tried recording anything to see if the same problem exists there. 
it's tough to test these things as i'm guaranteed a lock-up, ie: my drives
have to be fsck'd each time.

does anyone know of a way to safely debug this? can i catch the playback
thread before it pees on the floor, "NO! Geez hdsp, stream goes out the
urinal! ...hold that thing, damnit!!!" ?

dan.

The only safe way to debug this is to let someone else do it. ;-)

Use ext3/reiserfs and at least the time delays won't be as bad.

Do not have any other applications (email, etc.) open at the same time to
protect those databases.

Have a big, cold beer handy.....

(Sorry the mono thing didn't work. I can play Penguin-Command with lots of
sound and my HDSP 9652 driver works fine. Attempt alsaplayer for 1 second
and I lose all sound. Go figure...) ;-)

Can you please give us more informations about your system ?

* hardware (x86, PowerPC, SMP, laptop, cardbus or pci version of the hdsp ?)
* linux kernel version and patches applied
* alsa packages versions
* gcc version used to compile kernel and alsa modules

Re: Trivial hdsp.c patch to support rev 50 cards

[Dan Nyborg]

hello mark,

sorry i did not reply sooner, i've been bogged down with work as well as 
preparation for a show.

i am in the same state that i was  earlier. paul had suggested that it 
was a mid-level alsa problem... so i found an ancient (ie: small) hard 
drive and now have a reasonably fsckable system to "debug" with. i dove 
into the code and littered it with "printk" statements to try and catch 
something, but i haven't alotted sufficient time to this brutish attempt.

i am thinking that somewhere in the pcm open or capture callbacks, a 
pointer gets lost and some mem write process goes way out of range, 
hosing memory reserved for something else... uh, that's what i think 
atleast. it's bad, as i get no (hee hee hee)oops, whatsoever. however, 
my kernel programming knowledge consists of what i have crammed in over 
the last few weeks, so it is miniscule and confused ;).

by the end of next week, i'll be able to get back at it.

best of luck all around,

dan.

RE: Trivial hdsp.c patch to support rev 50 cards

[Mark Knecht]

Dan,
   Actually, I misread your description until Thomas pointed out that your
complete system is freezing, or al least that's what I read now. In my case
it's only the audio freezing and coming back. The system itself is fine.

   Sorry you haven't managed to get this working. We'll be around to help
when you do get back to it, and Thomas has made lots of headway with his
tools recently (hdspconf, hdspmixer) so maybe they'll help you get to the
bottom of this.

Best of luck,
Mark
