[linux-audio-user] No state is present for card

[Denis de Leeuw Duarte]

Hello again,

By the looks of it, the new alsa 0.9.3c snd-usb-audio driver loads correctly
with my Quattro, but I get this message when running the alsasound script:
"No state is present for card Quattro". I have the impression that the
documentation on the alsa site for .asoundrc doesn't really cover the newer
asound.state file, is that correct? For instance, alsa looks for a
state.Quatto{} clause in asound.state, but I can't find anything in the
documentation about this state clause. I don't really know what to put in
it. I tried Patrick Shirkey's .asoundrc file from the Wiki but that doesn't
work. Any ideas?

Thanks in advance and regards,

Denis de Leeuw Duarte

"State" means the current mixer settings, but the Quattro doesn't have any
mixer elements. The message is misleading in this case.

Ah thanks! Well it is working now!!!! I've been struggling with this device
for a week. First I had to return it to the store because they gave me the
wrong power supply and probably a defective unit. I'm very glad it works
now. Except for the fact that I can't use the device as a normal user (and
yes I am in the audio group) but this is probably so trivial I won't bother
you with it (yet;-)

after you've modprobed you'll need to do
chmod a+rwx /dev/dsp /dev/mixer /dev/sequencer /dev/midi

i find i need to do this manually each time (okay i could add it to my
startup scripts but i prefer the control of doing it by hand each time...)

We want normal music!", I think that was more like acting than anything

Thats one way of fixing it, but there is a better way (I believe that the
above needs to be done on every reboot which is a pain).

On my machine:

***@coltrane > ls /dev/dsp
crw-rw---- 1 root audio 14, 3 Aug 10 2001 /dev/dsp

Notice that the device allows rw access by the audio group. Therefore,
all you need to do, is for each user on the system who is allowed to
access these devices, as root:

adduser <username> audio

Cheers,
Erik

I see that too. I'll let the alsa-devel list know. Or Clemens will
probably read this.

I get this error while normal user which doesn't occur as root.

Well I fixed the access problem quite easily last night actually. This might
be a bit distro dependent since not all of them use the devfs, so ymmv. In
/etc/devfsd.conf add this:

LOOKUP snd MODLOAD ACTION snd
LOOKUP dsp MODLOAD
LOOKUP mixer MODLOAD
LOOKUP midi MODLOAD
REGISTER sound/.* PERMISSIONS root.audio 660
REGISTER snd/.* PERMISSIONS root.audio 660

Which then gives access to the audio group automatically. Add yourself to
the audio group and you're done. It didn't seem to work with me at first,
but I just had to log out of my kde session an login again and then it
worked.
