Re: [Alsa-user] /dev/dsp not found with kernel 2.6.16.29
Hallo Lee, Op 24 Sep 06 schreef Lee Revell aan [EMAIL PROTECTED]: Currently I'm running alsa driver 1.0.12 with kernel 2.6.16.27. This afternoon I tried to use kernel 2.6.16.29. I used 'make oldconfig' with the config of kernel 2.6.16.27. That made alsa complain that /dev/dsp could not be found. But it *does* exist: /dev/dsp - sound/dsp, permissions 664, owned by root:audio. What might be the problem? LR (Well, aside from the fact that apps shouldn't be using /dev/dsp LR in 2006...) Tell that the developers.I'm only a simple user :) LR Does aplay file.wav work?

[Alsa-user] cross-compiling alsa-plugins
Hi, I want to cross-compile (for arm) the alsa-plugins package, but I alway get the error: configure --prefix=/opt/arm-linux --host=arm-linux ... checking for pkg-config... /usr/bin/pkg-config checking for alsa = 1.0.8... Requested 'alsa = 1.0.8' but version of alsa is 1.0.3rc2 configure: error: Library requirements (alsa = 1.0.8) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them. But I have the cross compiled libasound library (1.0.9) under /opt/arm-linux/bin. I've tried to set PKG_CONFIG_PATH=/opt/arm-linux/lib (and PKG_CONFIG_PATH=/opt/arm-linux/lib/pkgconfig), but it didn't help. Could you please give me some hints? Thank you!

[Alsa-user] Pb with simultaneous SATA and ALSA I/O
Hello I have some problem using the SPDIF output of my SB Live card while performing I/O on my SATA drive. (See [1] for the whole story on the ALSA mailing list) My Yamaha amplifier does not recognize the AC3 (Dolby digital) stream from the sdpif plug while performing I/O on my SATA drive. If I have a lot of I/O (e.g. running md5sum on a 4Gb file), the AC3 stream is completely broken. If I have some I/O (e.g. reading a Hi-def movie), I get some AC3 drop-out even if the CPU is about 50%. I have the same result with DTS output. With PCM output, I've noticed a hi-frequency distortion, which means that the interaction between SATA and snd module occurs several thousands time per second. My set up is: - Debian Linux kernel 2.6.17 - Sound blaster SB Live 5.1 (snd_emu10k1 module) - SATA drive (sata_sil and libata module) - A7n8x deluxe mobo - AMD XP 3200 So far I verified that: - AC3 output works fine when SATA drive is left alone - AC3 output works fine when running md5sum on a PATA drive - DTS output works fine on the mobo SPDIF output (snd_intel8x0 module) even when running md5sum on the SATA drive. (cannot try AC3 stream because of Soundstorm chip :-( ) - Preemp kernel option does not fix the problem - when running md5sum on SATA drive, alsa driver report a starvation (xrun) every few seconds, not thousands of time per second. Could someone shed some light on this problem ? What can I do to help debug this problem ? Thanks [1] http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg17399.html - Take Surveys.

There is so much onboard stuff sharing interrupts on those boards that you might have problems because of that. Creative cards are not very good at dealing with anything other than ideal conditions from what I have gathered over the years. The manual for the board will tell you which IRQ goes to which slot, and I guess you want to avoid using a slot that shares with the SATA controller. It might not be interrupt related, it could be DMA starvation. This has been observed with some SATA controllers while testing the -rt patches. The symptom is that the latency traces show the machine going in slow motion. Dominique: try the -rt kernel, enable latency tracing and post the output. Lee - Take Surveys. Earn Cash.

You can enable it under Setup - Misc around. I was able to manage playing something to the outputs I liked, with managing the outputs with qjackctl. Starting the server gives out ...

I hope I have spare time at the weekend to try the .asoundrc files I have. Did you advance in setting up a working .asoundrc ? It seems nothing works with this card without a proper .asoundrc or .jackrc ...
