hi,Hi all,I'm almost at my wits end ("ARGH!"). Everything used to work pretty well... until I messed with my system once again (upgrading some packages and doing other things, or so I think). After having installed the 0.9rc7 Debian package (or around that time at least) and having rebuilt ALSA, I didn't manage to start ALSA properly any more:
i incurred in the same problem since two days, when i decided to upgrade my alsa driver from 0.9rc6 to 0.9rc7
some info:
i use a toshiba s3000-214 with an intel8x0 audio device
with 0.9rc6 alsa was running fine
i run debian unstable.
these are the relevant (!) package:
andrea@nb-venturi:~$ dpkg -l | grep alsa-
ii alsa-base 0.9.0rc7-2 ALSA driver common files
ii alsa-headers 0.9.0rc7-2 ALSA driver header files
rc alsa-modules-2 0.9+0beta10+5+ Advanced Linux Sound Architecture (drivers)
ii alsa-source 0.9.0rc7-2 ALSA driver source
ii alsa-utils 0.9.0rc7-1 Advanced Linux Sound Architecture (utils)
andrea@nb-venturi:~$ dpkg -l | grep gcc
ii gcc 3.2.2-0 The GNU C compiler.
ii gcc-2.95 2.95.4-15 The GNU C compiler.
ii gcc-3.0 3.0.4-13 The GNU C compiler.
ii gcc-3.0-base 3.0.4-14 The GNU Compiler Collection (base package)
ii gcc-3.2 3.2.3-0pre1 The GNU C compiler
ii gcc-3.2-base 3.2.3-0pre1 The GNU Compiler Collection (base package)

rc libstlport4.5g 4.5.3-4 gcc3-version STLport C++ class library
ii libstlport4.5g 4.5.3-5cjh2 STLport C++ class library compiled with gcc3
under /usr/src there was:
andrea@nb-venturi:~$ ls -l /usr/src/
totale 31756
-rw-r--r-- 1 root root 2157649 2003-02-07 12:16 alsa-driver.tar.gz
that is the debian way to put source tarball to upgrade some driver..
i compiled the usual stuff /usr/src/modules/alsa-driver
ad i installed all the modules with "make install"
than, at next reboot, the /etc/init.d/alsa script failed to run because there was a small glitch at line 93: a missing double-quote around $alsa_version
the i had to add /etc/modutils/alsa with all the aliases for the modules and i was up & running, or, at least, i was thinking.. :-(
the snd-intel8x0 goes up, from dmesg:
PCI: Found IRQ 10 for device 00:1f.5
PCI: Sharing IRQ 10 with 00:1f.3
PCI: Sharing IRQ 10 with 00:1f.6

PCI: Sharing IRQ 10 with 02:04.1
PCI: Setting latency timer of device 00:1f.5 to 64
intel8x0: clocking to 48000
but, if i try a "cat /proc/asound/version"
i get an oopps
