Re: [alsa-devel] [FFADO-devel] [RFC] libhinawa: a light-weight I/O library for status/transactions to ALSA FireWire devices

This is one of my > solutions to some issues between ALSA/FFADO. As I understand it, this library will be a thin wrapper around whatever kernel interface is used to communicate these details out to userspace (I think byte-type mixer controls are the preferred avenue at present). In principle I have no problem with this approach so long as it remains lightweight. The situation to avoid is the one we had with libraw1394; when the new stack came about the preferred way to interact with it switched back to the native kernel interface since (as I understand the situation) it was felt that libraw1394 didn't really provide a worthwhile API abstraction. Out of interest, is there any signficance in the library's name "hinawa"? > I hope to merge this library into alsa-tools package in future, and this > is a first RFC for it.

One thing to keep in mind is that while this is an issue for DICE devices it may not apply to others. The library API should be structured to keep in mind that not all features will be needed across the board. We don't want to burden all subsequent firewire-audio streaming drivers with baggage which is only required for a small subset. Regards jonathan

[alsa-devel] [PATCHv3 1/2] ALSA: fix emu8000 DRAM sizing for AWE64 Value
by David Flater 12 Jan '15

12 Jan '15

Applicable to any kernel since 2013: The special case added in commit 1338fc97d07a did not handle the possibility that the address space on an AWE64 Value would wrap around at 512 KiB. That is what it does, so the memory is still not detected on those cards. Fix that with a logic clean-up that eliminates the need for a special case.

[alsa-devel] [PATCH] ASoC: ad193x: Don't power down DAC in CODEC probe
by Lars-Peter Clausen 12 Jan '15

12 Jan '15

The DAC powerdown bit is managed by DAPM. Manually powering down the DAC in the CODEC probe function may cause unnecessary power state transitions which can lead to click and pop noises. So leave the DAC powerdown bit in its default poweron-reset state and let DAPM do all the management.
