[alsa-devel] Dummy module and sample rates
by Uli Franke 10 Oct '15

10 Oct '15

Hi Clemens, I fiddled around with the Dummy module and it seems to be the thing we're looking for. I observed a rather strange behavior though: I set the hw params sample rate to 44k1 without error, but a subsequent call of snd_pcm_start returns EPIPE. When setting hw params sample rate to 4k this does not happen. Did I miss anything?

[alsa-devel] Applied "ASoC: rockchip: Add rockchip SPDIF transceiver driver" to the asoc tree
by Mark Brown 09 Oct '15

09 Oct '15

The patch ASoC: rockchip: Add rockchip SPDIF transceiver driver has been applied to the asoc tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[alsa-devel] [PATCH 0/5 v4] ALSA: add helper functions for MIDI message transmission on IEEE 1394 asynchronous transaction
by Takashi Sakamoto 09 Oct '15

09 Oct '15

Hi, This patchset updates a part of my previous post: [alsa-devel] [PATCH 0/5] ALSA: add helper functions for MIDI message transmission on IEEE 1394 asynchronous transaction http://mailman.alsa-project.org/pipermail/alsa-devel/2015-October/098536.ht… (Besides, the patchset should have been version 3, thus this patchset is v4.) This patchset adds some helper functions for MIDI transmission via IEEE 1394 asynchronous transaction. Changes: * fix compile error due to missing member of structure. * improve comments Takashi Sakamoto (5): ALSA: firewire-lib: add helper functions for asynchronous transactions to transfer MIDI messages ALSA: firewire-lib: add a restriction for a transaction at once ALSA: firewire-lib: schedule work again when MIDI substream has rest of MIDI messages ALSA: firewire-lib: add throttle for MIDI data rate ALSA: firewire-lib: avoid endless loop to transfer MIDI messages at fatal error sound/firewire/lib.c | 138 +++++++++++++++++++++++++++++++++++++++++++++++++++ sound/firewire/lib.h | 56 +++++++++++++++++++++ 2 files changed, 194 insertions(+) -- 2.1.4
