hi,
still an other sound problem, this time with a Logitech Z515 wireless speaker.
It worked on my desktop on wheezy, and no more after the upgrade to Jessie.
It works On my wheezy laptop: the Z515 appears in /proc/asound/cards immediatly
after plugging the usb dongle.
It also works with the Jessie live cd, but with the installed OS, I get in the syslog:
new full-speed USB device number 3 using uhci_hcd
New USB device found, idVendor=046d, idProduct=ba10
New USB device strings: Mfr=1, Product=2, SerialNumber=3
Product: Logitech Wireless Speaker Z515
Manufacturer: Logitech
SerialNumber: 000d4493d340
snd-usb-audio 7-1:1.0: cannot find the slot for index 2 (range 0-2), error: -16
cannot create card instance 0
snd-usb-audio: probe of 7-1:1.0 failed with error -5
and in /proc/asound/cards, the other cards are seen, but not the X515.
I become really tired to spend so much time fighting against this OS
Has anybody an idea on where to look at?
best regards,

This should not have changed the presence of cards in /proc/asound/cards,
only their order.

This indicates you have a configuration problem with your ALSA system: the
plugin infrastructure eventually references a non-existent sound card.

This is completely wrong, this symbolic link should not be needed, and it
does not fix anything since it will disappear after the next reboot.
I have not read the rest of the thread, nor do I intend to, but I did not
want to let that kind of bad advice pass.

At last, I could solve the problemm. In case anybody is interested,
here is how:
in /etc/modprobe.d/alsa-base.conf:
options snd-usb-audio index=1
After that, and reboot, the Z515 is seen in /proc/asound/cards, and in 'aplay -L'
and the sound works with vlc or audacity, but not with aplay, speaker-test,
here is how:
in /etc/modprobe.d/alsa-base.conf:
options snd-usb-audio index=1
After that, and reboot, the Z515 is seen in /proc/asound/cards, and in 'aplay -L'
mplayer.
The output of these 3 programs is very instructive, and IMHO should be given
as an example in all programmers' schools!
-> speaker-test
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2,No such file or directory
->aplay woow.wav
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
aplay: main:722: audio open error: No such file or directory
-> mplayer file.mp3
... open '/dev/snd/pcmC1D1p' failed (-2): No such file or directory
with the first 2, impossiblle to guess what's wrong or missing.
with the 3rd one, you have the answer: just do
->sudo ln -s /dev/snd/pcmC1D0p /dev/snd/pcmC1D1p
and that's it!
Still difficult to understand why it worked with vlc, as it is configured to
->sudo ln -s /dev/snd/pcmC1D0p /dev/snd/pcmC1D1p
and that's it!
use the Alsa output.

May-be it should not, but it actually did.

the so-called "non-existent sound card" worked with vlc and audacity !!

It will not disappear after the next reboot, thanks to /etc/rc.local.

OK, it's not a fix, but a workaround.
If you don't like it, you are welcome to propose a real fix.
Until that, the link is needed, and I don't think you are allowed to call
that a bad advice.
I would be curious to know how you interpret the mplayer error message

Yes, I did read your post. I also know how ALSA works and that VLC and

audacity are probably opening a different device than aplay and mplayer. The
real test is aplay, since it is the program that does the least black magic
behind the user's back.

problem, this is definitely bad advice. But you will not bait me into
spending more time on it.

Very kind for vlc ans audacity developpers!

I do like "black magic" when it makes something to work

It's your perfect right not to spend time to help people (or
may-be you are unable to help), but in that case please don't pollute
the list with useless comments.

Anyone with Pierre's problem can use his solution to make his speaker work.
You have offered no better solution, even though one does probably exist.
Solved seems fine to me, and likely to help people with the problem.
And remember, you have twice said that you are not going to say anything more
or spend any more time. You'll do us all a favour if you stick to that,
unless you have something helpful to say that will solve the problem in a
better fashion than Pierre has.

Or they can use the solution to make their problem worse. This is the most
likely outcome with such a hacky work-around.
This is precisely the problem I am warning against with this kind of
non-solution: if you are lucky, you may be able to get things working right
now, but you are preparing a lot more trouble for later. This is ok if you
are doing this for yourself, after all you are just wasting your own time.
It is not ok to advertise it without proper warnings.
I have come to expect that kind of attitude on the Ubuntu webforums, I would
have hoped it was more frowned upon on Debian mailing lists. I am sad to
observer it is not the case.
> You have offered no better solution, even though one does probably exist.
I have given relevant information: the kernel option only changes the order
of the sound cards, aplay is the preferred tool for debugging, the error
message points to a faulty ALSA configuration.

My message was not intended for Pierre. Pierre can fix his problem with
"sudo rm -rf /" for all I care. My message was intended for all the readers
of this list archives who may be tempted to follow Pierre's advice without
realizing it will make their problem worse.
I do not intend to reply Pierre further, and you neither. That does not mean
I will not if someone has new arguments for the discussion, or on the
opposite adds more misleading information.

thanks for your comments.
it's obviously useless to discuss with that guy, as he is only able
to insult, but unable to provide an help (unless you name "help"
the only hint "faulty Alsa configuration" !!)

sound-wise, Alsa-wise, it might be edifying, if the speaker works using
it without any intervention or workaround on your part.

It's of course the 1st thing I did when I saw that the Z515 worked

without any intervention of my part, but I was not clever enough to find
anything useful. Now that I found the workaround with the link, I'll
check whether this link exists or not when booting the cd live.

-D, --device=NAME select PCM by name
You probably need to use alsactl to clean up the state - for me it was
useful with new sound cards
