Re: [linux-audio-user] shuttle xpcs as linux music boxes?

by robcanning

hi, I just bought one of these little boxes (Shuttle Spacewalker XPC SN41G2 nForce2 Aluminium Barebones System - AMD Athlon XP to use for an installation and have installed redhat9 on it and soon will be planetccrmaing it - it is a very quiet machine as it comes and i believe you can get an optional super quiet power supply for it - very easy to build/configure - i'll let you know if i run into any audio worries. Does anybody know if i can access more than 2 the 5.1 outputs on the onboard audio chip with PD or should i go ahead and get an SBLive for 4 outs? nVida Corporation nForce Multimedia audio controller [VIA VT82C686B] (rev a2) nVida Corporation nforce AC97 audio controller (MCP) (rev 1a) rob -- robcanning <rscanning(a)eircom.net> www.robcanning.utvinternet.com

by Mark Knecht

Hi, A new laptop I got uses somethign called SoundMAX under Windows. dyne:bolic boots and brings up Alsa running something called snd-atiixp, and lspci showing a bunch of ATI chips, but looking on the Alsa page I'm not finding ATI. Can someone point me towards the correct configuration page on Alsa for this sound chip? Thanks, Mark

[linux-audio-user] beginner

by Josenildo Marques

Hello. I've been out of luck trying to work with sound on Linux. My experience with Audacity, Jack and Ardour haven't been successful at all. I was trying to create a .asoundrc file as, from what I read, it would be one of the first necessary steps. My soundcard is [cyb@kali cyb]$ cat /proc/asound/cards 0 [Live ]: EMU10K1 - Sound Blaster Live! Sound Blaster Live! (rev.8) at 0xa800, irq 10 and it's working well and I'm running Mandrake Linux 9.2 with Gnome. My attempt at editing a .asoundrc file is shown below pcm.!sb { type hw card 0 } ctl.!sb { type hw card 0 } pcm.jackplug { type plug slave { pcm "jack" } } pcm.jack { type jack playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_2 } } which I copied and pasted from the Alsa site. Apparently it is working because when I issued some commands to play a file they worked. [cyb@kali cyb]$ aplay -d sd docs/voz.wav Playing WAVE 'docs/voz.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo[cyb@kali cyb]$ aplay -djackplug docs/voz.wav Playing WAVE 'docs/voz.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo However, Jack is not working properly and when I try to run Ardour all my running apps are killed and disappear. Jack shows the following messages: JACK compiled with System V SHM support loading driver .. open starting engine cannot set thread to real-time priority (FIFO/10) (1: Operation not permitted) cannot set thread to real-time priority (FIFO/20) (1: Operation not permitted) **** alsa_pcm: xrun of at least 10.319 msecs I'm very sorry if the message is bit lengthy, but I wanted to give all the info that I think is needed. Any tip or hint appreciated. TIA -- josenildo marques icq #289971493 homepage http://cyb.ezdir.net registered linux user #341648 ********* "Mistakes are the portals of discovery." James Joyce

[linux-audio-user] Help for isisalsa driver coding

by Felipe Sologuren

Hello: Sorry by my english. I'm request for people could help in coding of isisalsa driver (for Guillemot Maxistudio Isis). I'm not a developer, only entusiast user, and people developing in this project "know little of alsa coding rules" and/or got little time. The status is only playback and still have bugs for work with alsa applications, this is the area for my request. The reversing is complete. Maybe the card isn't a professional audio device, but offer the possibility of several users to switch their environment to linux (for me it does) and cause guillemot closed win2k/xp support for this card. Feel free to forward (please). http://uk.guillemot.com/brand/gamme/son/msisis/isis.html http://fr.guillemot.com/brand/gamme/son/msisis/isis.html http://sourceforge.net/projects/isisalsa/ irc://freenode/isisalsa http://www.estudiohum.cl/Isis.htm Thanks for hear us ;) Felipe Sologuren Sound Engineer

Yet, in these select instances it does not work even though neither the cardbus driver nor the actual card driver do not report any particular problems. Hence the only logical explanation is that there is something wrong with the pcmcia controller driver. This card does tax the throughput of the cardbus like no other card I can think of, hence the problem may be more widespread, but exhibits itself just in this case where the cardbus is being pushed to its limits. Yet, the hardware is not the issue when the same notebook/soundcard combo works flawlessly in WinXP. Hope this helps! Ico

Re: [linux-audio-user] snd-hdsp+cardbus=distortion -- the sagacontinues (cardbus driver=culprit?) UPDATE: 99.9% sure it is the cardbus driver yenta_socket

by Tim Blechmann

> What needs to happen is that the card driver author needs to > investigate what is going on, and, if it seems related to the core > PCMCIA core or the socket driver, we need to get involved. he pointed out that it's probably a kernel problem ... we don't want you to solve problems of the alsa driver, but we suspect there is a problem with the cardbus bridge... basics: 1.) the card is a combination of 2 devices: a interface device, either a pci or a cardbus card, and a dsp device, either digital or analog audio ... no problems have ever been reported about the pci interface, so it's likely to be a problem with the cardbus interface ... although i have to admit, that there are only 3 reported systems that have the problems, we experience ... but these systems are completely different ones (p4 / amd64, different cardbus bridges) 2.) the dsp device has an internal matrix mixer, that's independant from the computer (this audio data isn't sent to the computer at all) ... in fact it's possible to set the matrix mixer and unplug the dsp device from the computer ... there are three problems, that show the situation: 3.) if we start an audio application that produces interrupts on the hdsp device, some of the audio data that's been transfered to the computer will be copied or mapped to the buffer of the audio data that's been transfered from the computer to the corresponding output. this could either happen - inside the device itself (i doubt that, since the same driver, the same firmware, the same devices are working without and problems on other linux machines or with windows on the same machine) - inside the cardbus bridge - inside the kernel 4.) if we start the audio playback, the audio playback seems to be distorted: one block of samples will be followed by one block of samples of 0 (zero) ... note that these block are not the blocks of data, that are sent to the hdsp during one interrupt. it's usually 32 samples of sound followed by 32 samples of silence, the driver sends blocks of 64 to 8192 during one interrupt depending on user settings... iirc one sample is 24 bit on the other hand the blocks of silence aren't missing, but the alsa layer will adapt, so that it takes twice as long as it should to play back a soundfile (i'm not sure if it's because of the alsa soundfile player or of the driver) 5.) the reason why we (or at least i) think, that it's a problem with the cardbus interface, is because of jack's output ... jack is both an audio connection interface for different softwares and a very good alsa implementation... using jack as super user in realtime mode, it complains about latency problems: delay of xxx usecs exceeds estimated spare time of yyy; restart ... at the default sample rate of 48000 xxx only about 0.06 % bigger than yyy ... on the other hand, i only get this error on sample rates of more than 32000 ... although the sound at 32000 is distorted, as well... other thoughts i had: 6.) the distortion isn't affected by the block size / the number of interrupts ... it is affected by the samplerate ... that's why i think, there are always 32 samples (768 bit) followed by 32 samples of silence (768 bit zero ???) 7.) the problems occured on different cardbus bridges: ENE C1410 (ico / mandrake) o2micro6933 (myself / gentoo) Texas Instruments PCI1250 (timothy / red hat) i don't know what's the reason for the problems, the latency or the mapping problem, or if there is something else that results this problem ... but since it's a software and not a hardware issue (works fine with windows), i'd like to get into it, and at least try to solve it ... but since i'm neiter a kernel hacker nor i have any idea about the hardware internals, i'd need some help from some people, who are able to help me... i don't want some people to solve my problems for me, but i'd appreciate any help of people, who know what's going on inside the computer... cheers ...

[linux-audio-user] Stuttering via HDSP, Cardbus, Multiface?

by Timothy Polashek

Hello! Has anyone experienced stuttering and very slow playback via RME multiface, cardbus, and Alsa on a notebook, or other computer? I am using the CCRMA low latency kernel on Fedora. How can I fix it? My machine has is 2.8 Pentium 4, plenty of horsepower, and two pcmcia slots (only one works with hdsploader for some reason). I know that I have alsa installed correctly because when I modify the modules.conf file to use the internal sound card and speakers, everything is very fine playing audio back via xmms, audacity, csound(from the command line), and pd. However, once I switch over to the hdsp in the modules.conf file, everything runs but extremely slow... Audacity will take a minute to launch and then will play back a 2 minute file over 5 minutes, the sound out of the multiface is stuttering and distorted. (Very beautiful in a twisted sort of way!) My guess is that the problem is the pcmcia bus is somehow 2000 times slower than it should be.. csound seems to confirm this hypothesis from the command line when attempting realtime synthesis: $ csound -d -o devaudio toot01.orc toot01.sco Using default language 0dBFS level = 32767.0 Csound Version 4.23f03 (Nov 18 2003) orchname: toot01.orc scorename: toot01.sco orch compiler: 32 lines read sorting score ... ... done Csound Version 4.23f03 (Nov 18 2003) displays suppressed 0dBFS level = 32767.0 orch now loaded audio buffered in 1024 sample-frame blocks hardware buffers set to 2048 bytes writing 2048-byte blks of shorts to devaudio SECTION 1: ftable 1: new alloc for instr 1: /dev/dsp: could not write all bytes requested /dev/dsp: could not write all bytes requested /dev/dsp: could not write all bytes requested /dev/dsp: could not write all bytes requested /dev/dsp: could not write all bytes requested /dev/dsp: could not write all bytes requested [1]+ Stopped csound -d -o devaudio toot01.orc toot01.sco Thanks for the help! -Tim
