After using skype for some time, my sound became inaccessible: I have tried to restart my sound system, but it failed. linux:/ # rcalsasound reload Shutting down sound driverERROR: Module snd_mixer_oss is in use ERROR: Module snd_via82xx is in use ERROR: Module snd_ac97_codec is in use by snd_via82xx ERROR: Module snd_ac97_bus is in use by snd_ac97_codec ERROR: Module snd_pcm is in use by snd_via82xx,snd_ac97_codec ERROR: Module snd_timer is in use by snd_pcm ERROR: Module snd_mpu401_uart is in use by snd_via82xx ERROR: Module snd_rawmidi is in use by snd_mpu401_uart ERROR: Module snd_seq_device is in use by snd_rawmidi ERROR: Module snd is in use by snd_mixer_oss,snd_via82xx,snd_ac97_codec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device failed Starting sound driver: via82xxFATAL: Module snd_via82xx not found. failed My hardware:AMD Sempron CPU, 1GB RAM, VIA KM400 chipset, VIA 8237 audio My Software:SUSE 10.0 RC1, Skype 1.2
Most likely a thread of skype or some other process is still alive, which keeps touching the OSS device. That can't be fixed in the init script safely. It's rather a problem of application. Just make sure that you killed the app completely. Alternatively, you can try aoss to run apps with ALSA OSS emulation. It'd be even a better option (if it works).
Well, no, I have killed all thread of all software that accessing my sound device. Anyway - the only possible solutions to this problem is either reset my computer (bad solution) or make the driver that gets " rcalsasound reload " command to invalidate all calls of all apps to a sound devices, by redirecting those app's audio output to /dev/null (smart solution) i.e. If you have a program in memory (say XMMS) that u forgotten to shutdown, but u have restarted the audio drivers, XMMS won't crash, the OS won't crash, u won't need reset your PC, just you will hear sound no more.
It's not enough to kill only threads but also to kill the whole process since many programs restart threads automatically.
Resolved to WONTFIX as rcalsasound doesn't guarantee the restart of badly mannered processes.
