Incidentally, the Documentation of the ALSA-DSP MADI Driver (this is another interface, but from the same manufacturer RME) has a nice explanation of the "Precise Pointer" parameter: https://www.kernel.org/doc/Documentation/sound/alsa/hdspm.txt
> Hardware-pointer -- 2 Modi > The Card supports the readout of the actual Buffer-pointer, > where DMA reads/writes. Since of the bulk mode of PCI it is only > 64 Byte accurate. SO it is not really usable for the > ALSA-mid-level functions (here the buffer-ID gives a better > result), but if MMAP is used by the application. Therefore it > can be configured at load-time with the parameter > precise-pointer. ... > Precise Pointer -- off interrupt used for pointer-calculation > Precise Pointer -- on hardware pointer used. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/648992 Title: Hammerfall DSP needs alsactl init db entry to work with Pulseaudio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-utils/+bug/648992/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
