PDAudio on the Sharp Zaurus SL-C3200 (also known as "Spitz" and "Teriier") ?
I spoke with Core Sound the PDAudio card's manufacturer, briefly on the telephone on August 4th 2006. I was informed that the card works with Linux laptops, but only Windows PDAs. For Linux, though, I should consult ALSA. (The card is a CF card and has one input: 'optical sound', which it converts for use by the computer. No external output.) There is work on PDAs on the web: e.g. http://www.mega-nerd.com/PDAudio/pdaudio.pdf and http://www.mega-nerd.com/PDAudio/v0.7.1/pdaudio/armv4l/pdaudio_0.65-6_armv4l.ipk The files are though dated 2004. The Core Sound site offers a download http://www.core-sound.com/pdaudio-cf/9.php of "a tarball containing PDAudio Recorder (Linux) and the 0.9.6 ALSA package (including the PDAudio-CF driver)" from http://www.core-sound.com/pdaudio-cf/pdaudio-alsa-20031001.tar.gz. The same page notes "2/26/2004: The folks maintaining Linux's ALSA system have moved PDAudio-CF's driver the alsa-driver module to alsa-kernel tree. It is merged to latest 2.6.3-mm3 kernel from Andrew Morton and will be integrated into Linus's official 2.6 tree sometime soon." The Core Sound tarball provides (among other things) /usr/bin/PDAudio. Calling that on the Zaurus with Opie resulted in a series of dependency problems. These were easily solved (note (a) OpenZaurus has "libxi" not the requested "libXi" and that (b) another is satisfied by a symbolic link from *.so.1 to *.so.0). The output then is: Control hw:1 open error: No such file or directory OPTICAL Bad directory : /home/user which is fair enough as the card is not recognised. cat /proc/asound/cards only lists the onboard card not the CF card. (Though the "Configure PCMCIA/CF Card" dialogue on Opie does correctly list the card by "CardName:".) lsmod does not list "snd-pdaudiocf". There is no module of that name (or with the string "pdaudio") in the directory tree. The Opie / OpenZaurs provides ALSA packages, e.g alsa-utils-aplay_1.0.10-r0_arm.ipk But these do not _seem_ to support the PDAudio card (???). Certainly installing these and _then_ the pdaudio-alsa-20031001.tar.gz tarball causes overwriting and errors such as: ALSA lib pcm_hw.c:685:(snd_pcm_hw_mmap_status) status failed : No such device or address arecord: main:503: audio open error: No such device or address. There is a helpful page "Core Sound PDAudio-CF" on the ALSA site, but this presumes compiling from ALSA sources. Something I cannot even manage on a laptop (with a 'distribution') and I suspect is non-trivial (if possible) on a PDA. This seems to have been a recurrent question when I have googled, but I have not found any successful reports (except arguably Erik de Castro Lopo's paper (the PDF cited above) from January 2004). Can anyone add to the above? Thanks, Michael ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
