Description Féliciano Matias 2004-10-01 17:10:13 UTC

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3)

Description of problem:
system-config-soundcard suppose that sound card are ordered in the
same order than kudzu, suppose numbering start at 0 and are continuous
(0, 1, 2... but not 0, 2).

I don't carefully check if it's an inappropriate use of kudzu, or a
missing feature.

Version-Release number of selected component (if applicable):
1.2.10-1

How reproducible:
Always

Steps to Reproduce:
In my system.
Order Kudzu detection card :
1 - via82xx
2 - ens1371

my modprobe.conf :
1 - ens1371
2 - via82xx

Launch s-c-sc and check the order of the card.

Actual Results:
1 - via82xx
2 - ens1371


Expected Results:
1 - ens1371
2 - via82xx

Additional info:

So, s-c-sc does not support none continuous card index (0, 2 for
exemple) and if the first (and only) sound card have an index
differente than 0.

"As expected", asound.conf got bad values and "play test sound" is
broken or use the wrong sound card.

We don't support changing the order of the cards in modprobe.conf as
compared to kudzu. They're supposed to match (as kudzu will write the
modprobe.conf).

If you can find a case where kudzu will leave "holes" in the indexing,
and are able to reproduce it without modifying the modprobe.conf by
hand, please re-open.

Comment 2 Féliciano Matias 2004-10-03 13:17:49 UTC

I need to change the order set by kudzu because OSS program ignore
asound.conf.

FC3 chose to provide OSS emulation (it's a kernel option that _Fedora_
enabled, Gnome support OSS, _Fedora_ provide sox (play program),
ogg123 use OSS interface by default, ...) , then FC3 should provide
support for OSS program.

Anyway, if the cards are swapped in the system or if the first card is
removed from the system,  s-c-sc still broken (kudzu don't update
modprobe.conf to enforce continuous index that start at 0).

If you want a continuous index that start at 0, this imply :
- no hardcoded index in /etc/modprobe.conf (or modprobe.conf properly
update)
- drivers always loaded in the same order
- no hotplug

Feel free to open a bug to kudzu because it don't guaranty a
continuous card index _only_ for s-c-sc. S-c-sc is the only programme
in FC that rely on this "feature". Other programs that deal with
multi-card work perfectly without this.
Try this :
$ modprobe snd-dummy index=5  # dummy or any other driver
$ gnome-volume-control

Bug re-open. If you don't understand the issue, at least I hope you
will set it to RFE.
If you chose to close the bug, then that means I should open a bug for :
- kernel provide useless OSS support
- play (from sox) use OSS
- ogg123 use OSS by default
- aumix use OSS
- ...

yes, this bug is still here...
