[alsa-devel] [PATCH] Drop Vladimir Barinov's e-mail address

29 Sep '08

Every e-mail I've sent to Vladimir Barinov bounced back to me, so I guess he no longer works at MontaVista.

[alsa-devel] Compiling an Alsa plugin with Intel compiler.
by Motti Daniel 28 Sep '08

28 Sep '08

Hello people! I'm working on an Alsa plugin for the Xandros Linux distribution my plugin runs very well except it consume about 20% of resources from the target machine (eee pc at 1.6Ghz) I'm trying to compile the same code with Intel Compiler (version 10.1.017) (before that it was compiled with gcc 4.1.2) the plugin compiles well but when I try to play music it tells me that the plugin library (the .so file in /usr/lib/alsa-lib/ is not there. I tried to analyze the symbols in the executable and found that the difference between gcc and Intel compiler is a list of symbols with a suffix __FUNCTION__ or __PRETTY_FUNCTION__ is this the problem? any suggestions? can you tell me what are the minimum alsa requirements from a dynamic library so it can be loaded and run as an Alsa plugin? thanks! Motti Daniel.

[alsa-devel] GeForce 8200 HD audio seems to work!
by Vedran Miletić 28 Sep '08

28 Sep '08

I just installed Linux on ASROCK GeForce 8200 board. Being a relatively new chipset, I had a couple of issues booting older kernels, finally settling for Debian lenny since it had a CD that booted. I was worried about onboard audio, since it's one of thousands of HD audio solutions, and I expected to have problems with it. To make the long story short: 1.0.16 -> only noise, doesn't sound close to track played 1.0.17 -> sound + lots of noise, but you can recongnize the song that is playing takashi's sound-2.6 -> everything works (including front panel) + HDMI audio seeems to be supported Massive props to whoever made it work. I just have two questions: 1) On RS690 I used to have separate device for RS690/RS780 HDMI (that is HDA ATI and HDA ATI HDMI), on NVIDIA I only have HDA NVIDIA, which has subdevice for HDMI, why? 2) alsamixer says: Card: HDA NVidia | Chip: Generic 10de NVIDIA MCP78 HDMI. Shouldn't chip be "Realtek ALC662 rev1" or something like that? Also, why does it say Generic 10de? Where is that read from? Regards, -- Vedran Miletić
