USB-Audio.conf uses the card_name function, which is not defined

[Michael Baumann]

The alsa-lib package uses a USB-Audio.conf which again uses the card_name function to enable dmix depending on the actual USB soundcard.

Now whenever using a USB soundcard device I get:

------------------------------->-8-----------------------------
ALSA lib dlmisc.c:108:(snd_dlsym_verify) unable to verify version for symbol snd_func_card_name
ALSA lib conf.c:3488:(_snd_config_evaluate) symbol snd_func_card_name is not defined inside (null)

------------------------------->-8-----------------------------

According to alsa upstream changelog this function was added between 1.0.14-rc2 and 1.0.14-rc3

Please test the fixed version by replacing /usr/share/alsa/cards/USB-Audio.conf with http://adhd.irule.net/~crimsun/feisty-freeze-exception-request-alsa-lib/USB-Audio.conf

Should I still test it even if you removed the patch for now?
(the file is not available at this place).

Michael

Yes, please still test. Prepend "ignore." to feisty-freeze[..] in the URL.

The config is working fine here, dmix'ing as it should with my card.
Softvol would be nice, though ;) Will try to add it.

Michael

In Feisty+1, alsa-lib 1.0.14 (or newer) will be used, which will obviate the hacks in the above USB-Audio.conf that I posted.

Closing this bug, as the original issue is now fixed in Feisty.
