i think there are two share devices in alsa-lib or with very similar names. 1. share device 2. shm (shared memory device)
what the share device is good for? i dont know, and it doesn't worked for me. i think i tried it only with the current tarbal and not with cvs-version. the shm-device works in conjunction with aserver i set up a sample configuration to try it out, look in the html-file attached with this mail, but aserver doesnt support concurrent streams to one hardware-channel, i got an error from aserver trying to write to a currently open device, such as 'device is busy' or so. maybe depends on the souncard-driver, dont know, didnt had time to look into the source. ____ joy On 19 Apr 2002, Ivica Bukvic wrote: > Thank you for your reply.
