I'm using alsa under Debian Lenny. I don't know whether i have flaky hardware ( Intel 82801CA-ICH3 ) but i find that playing sound files works only intermittently. When it doesn't work, aplay and speaker-test both hang with no sound. I can fix this by running alsaconf, but that's a pain as it is interactive. I'd settle for a non-interactive way of running alsaconf. Please advise. TIA Charles |

Hi ALSA users, I am facing an issue with CPU load while using ALSA lib 1.0.19 or ALSA lib 1.0.20. During play out, when under normal conditions, (i.e. no under run condition occurs) the CPU load is less than 10%. But, whenever under run occurs, the CPU load shoots up to more than 50%. This seems to be an issue with ALSA framework itself, as many have posted their comments along similar lines on the web. I am pointing to one of them which is along the similar lines. (https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/277243). I think the load issue is independent of the CPU. I am developing my application on TI processor. I am a beginner for ALSA. Can anyone help me out with a possible solution for this problem? Pease let me know, if you have some pointers which can help me, solving this problem. Kiran Kumar A. |

What is the output of cat /proc/asound/cards in both cases?

Dominique, It's take until now for sound to go down again, so am now attaching as files the output you requested. Apart from superficial ordering of names, they look identical to me. I created the module listing with the following, so i hope there's nothing of interest missing... sudo lsmod | grep snd | sort >~/bad-sound.log Kind regards, Charles Dominique Michel wrote: > Le Sat, 25 Jul 2009 06:36:44 +0100, > Charles Johnson <cj...@pr...> a écrit : > >> I'm using alsa under Debian Lenny.
