When upgrading to libasound2 1.0.23-1ubuntu2 my usb sound card stop being discovered by programs like aplay, mumble.
aplay -L will not list the usb sound devices anymore.
The attachment will show my problem before and after installing the latest version of libasound2.
ProblemType: Bug
DistroRelease: Ubuntu 10.10
Package: libasound2 1.0.22-0ubuntu7
ProcVersionSignature: Ubuntu 2.6.35-22.33-generic 2.6.35.4
Uname: Linux 2.6.35-22-generic x86_64
NonfreeKernelModules: nvidia
Architecture: amd64
Date: Thu Sep 30 15:02:12 2010
InstallationMedia: Ubuntu 10.04.1 LTS "Lucid Lynx" - Release amd64 (20100816.1)
SourcePackage: alsa-lib |
-- StableReleaseUpdates candidate (for Maverick) information follows --
Impact statement: Due to changes in alsa-lib configuration file parsing (an overly-optimistic short-circuit) as shipped in Maverick final, certain virtual hw devices and audio cards that lack a definition file in /usr/share/alsa/cards/ are not exposed properly to userspace. This impact is manifested via missing virtual hw devices and/or cards. The original description below (i.e., this bug) contains an example of the former; bug 637947 contains an example of the latter.
Fix: It is worth noting that, to properly address both bugs mentioned above, both source changes and default configuration file changes must be made. These changes are contained in debian/patches/lp652035-fix-missing-hw-devices.patch and debian/patches/lp652035-use-extended-namehints.patch, respectively, as seen at http://bazaar.launchpad.net/~ubuntu-core-dev/alsa-lib/ubuntu.new/revision/66.
Minimal patch: http://bazaar.launchpad.net/%7Eubuntu-core-dev/alsa-lib/ubuntu.new/diff/66
TEST CASE: One test case is provided in (the entirety of) bug 637947. Another is given below.
Regression potential: There is a *very* low probability that (native) ALSA applications may not be equipped to handle the additional information exposed by extended hints (enabled by debian/patches/lp652035-use-extended-namehints.patch). In practice, this probability has been so trivial as to be negligible. Further, there would not be crashes, only additional virtual hw device(s) exposed in the UIs of graphical ALSA applications that offer potentially-confusing device strings. This probability is sufficiently negligible in light of its afforded fix of exposing sufficient information to userspace to "make audio devices work."
