[Alsa-user] Metallic recording in cs46xx on Thinkpad T22
Hi everyone, I ran over a lot of Internet search and could not find any clue to this issue. I am trying to record sound on an old Thinkpad T22 that uses the cs46xx sound driver. Each time you start to record you have a 10% chance of having the recording completely distorted and having a metallic sound. When you look at the waveform it looks as though there are small segments with sharp transitions between them, a little like if these segments were moved a little from their correct place. I've tried many many combination and none gives a solution, including - Native OSS, 3.92, 4.0 - kernel 2.4, 2.6.11, 2.6.26 (rh7.3, fedora 1,2,7,8) - Knoppix live CD - Activate thinkpad=1 for the module - Using native ALSA or OSS emulation. - Changing fragment size - Resetting mixer setting before recording - Changing recording format LE,BE, 8bit, 16bit - Changing recording frequency - Disable ACPI - Change IRQ of the sound-card - Using a low-latency kernel and giving the recording process real-time priority (FIFO_SCHED) None gave an improvement. It works fine on the Win2k system that is installed on the same computer. Does anyone have any clue to what might be going on? Is there any way to do a hard reset to the sound card (without unloading-reloading the modules)? Thank you for the help. - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Alsa-user] looking for some advise
Hi Romeo! I don't have neither. But I have an M-Audio Delta 1010LT, which I suppose is RELATIVELY close to the revolution 5.1. If they also use the ICE-chip, then they are nice. I also remember, that we had a lot of traffic about the revolution cards here. Since I didn't notice those mails for a while, I think it's a good one. That all sounds very vague, but still... Did you take a look at the alsa supported cards? If so and if the Revolution pops up there, then I'd say: Have a go at it! My Delta has very nice quality, very reasonable lowlatency and the BIT-depth/samplingrate should meet your requirements perfectly. Btw.: The reasonable lowlatency is mostly due to my system. A better PC than mine (1.8GHz CPU, average Harddisk, DDR-RAM) should really get you 64-128 periods latency with JACK. HTH.

Re: [Alsa-user] Metallic recording in cs46xx on Thinkpad T22
Each time you start to record you have a 10% chance of having the recording completely distorted and having a metallic sound. I know that sound. And it is quite ugly. On my snd-hda-intel board(nVidia MCP61), I have to increase the number of periods to overcome this sound. default of 2 increased to 3 and all was fine, in jackd -n 3. For arecord you might look at different than default buffer/period sizes. It's basically a latency issue. Other considerations are to give the audio group realtime permissions so things like ethernet traffic doesn't cause clicks and other distortions in the sound. /etc/security/limits.conf HTH, James - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Alsa-user] Preferred way to disable dmix
To use your second card, you have to specifify the device somewhere. If you want just the hardware abilities, just use the hw:1 device instead of default:1 or whatever you are using now. Using hw:1:0, I get the error message sample format non available most of the time, I guess the reason is that it is a 24bit sound card and my files are 16bit. So what I want is: No dmix, but automatic conversion to 24 bit. Is there a simple way to do that? plughw:1 should do exactly what you want from it, it seems. Yes, I was not aware of plughw. Thanks for the hint. (your default PCM is defined in $PREFIX/share/alsa/cards/ICE1712.conf) On my system it is /usr/share/alsa/cards/ICE1712.conf. Should I really edit that file? I have some hesitations to touch files in the /usr/-directory No, that was just showing you were things are. If you'd really want to change things you'd redefine the default device in /etc/asound.conf or ~/.asoundrc ok, thank you. ~Michael - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Alsa-user] 64 bit Compilation/Installation problem
Hi: I seem to have a problem with Alsa 1.0.16 when compiling. My system is: an Open SUSE 10.2 running on a Intel DP965LT mobo, with an Intel Core2 Duo E6420 processor. 2 G Ram. Intel HDA sound card, which has given me lot of problems. OpenSUSE 10.2 comes with Alsa 10.0.14a, which does not seem to properly support the Intel HDA chipset. So, I wanted to upgrade to Alsa 1.0.16. I downloaded all available packages from the Alsa site, built and installed the driver (using --with-suse=yes), ran alsaconf and rebooted. So far so good. I built the library, and installed that. I try to build the utils, but it fails with the error no TLV support in alsa-lib. I check the date on /usr/lib64/libasound.so.2.0.0, only to find it was NOT updated with the libray installation, yet the version in /usr/lib was updated. Temporarily symlinking libasound.2.0.0 in /usr/lib64 to /usr/lib allows the compilation of alsa-utils to proceed and complete without error. BUT, all other applications that use /usr/lib64/libasound now complain about wrong ELF type, ELFLIB64, HuH??? Not being a real programmer (Hardware engineer, retired), this says to me that: a) Perhaps the installation of alsa-lib is placing the library in the wrong directory on 64 bit systems. b) If the ELF type in the /usr/lib64 directory IS 64 bit, why is that causing a complaint? At that point, my head aches and I need some help and guidance, please. -- Roger PryorEmail: [EMAIL PROTECTED] Vancouver, Canada - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Alsa-user] Metallic recording in cs46xx on Thinkpad T22
Sadly, I've already tried all of these to no avail. What recording application are you using? I've had issues where audacity would give me that metalic sound and ardour+jackd would not. And vice versa. Depending on versions and whatnot. Beyond that I really can't offer any more insight without additional info. Like alsa version, kernel version, contents of /proc/asound/cards, .asoundrc, and whatever else might apply. Aside from upgrading to the latest kernel and latest version of alsa. It might be a known and already fixed issue. For audacity, most times I end up compiling it from source with the --with-portaudio=v19 parameter to work around various issues. Although it looks like debian caught on and now supplies a version with that option. HTH - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Alsa-user] asound.conf
Hi, I started to play with ALSA 2 days ago and Im trying to figure out how
ALSA works and how to add PCM devices in the configuration file.
I wrote a simple plugin for my microphone which is supposed to convert the
data into a 32 bps format. Here is how it looks like :
pcm.jcb-in-1 {
type hw
card 0
device 2
}
ctl.jcb-in-1 {
type hw
card 0
}
pcm.MicPlug
{
type plug
slave
{
pcm jcb-in-1
format S32_LE
}
}
So now if Im opening the PCM device named MicPlug and start reading on it, Im
expecting (which may totally be wrong) that the data I read will be in a
32bps format, which is never happening. In fact, the data I read is exactly
in the format that I set using snd_pcm_hw_params_set_format. Is the
conversion supposed to happen or am I expecting something that is totally
wrong?
Also is there any good documentation about how the asound.conf file works? I
found some stuff on the web but it rather sucks.
Thank you!

Re: [Alsa-user] recording from /dev/dsp
Whether this works will depend on your hardware. Some devices support capturing the audio output, some don't. Well, I swapped it around so that the onboard sound was card 0 and it works that way. But the quality of what gets recorded is bad, actually hideous is more appropriate. From studio quality to sounding like there's a waterfall in close proximity. After normalizing to bring it to audible levels. Not quite what I want. Perhaps there's some other way to get flash audio extracted that isn't as hideous. arecord -D hw:0,0 -t wav -f dat tempfile.wav Works but hideous. As I notice a button for downloading an .mp3 of the clip in the flash. Which doesn't seem to work in linux.
