Hi. I hope this is the right place to send
this, considering the dearth of messages in the archive for 2002.
I have been getting the following error from my

Hello ALSA mailing list,
I have following questions about SBlive card.
1. Does the driver for Sound blaster live card (SBlive card) only allow
playback through bus mastering? Can the data be moved by CPU as well?
2. If the driver does only bus mastering, then can anyone please tell
me whether

Hi,
I wonder if I am right to write audio packets to substream->dma_addr ???
