[alsa-devel] intel 8x0 ALSA driver in virtualbox - choppy sound
by Lex F 17 Aug '10

17 Aug '10

Dear all I am having problems with getting sound running well in Arch Linux guest (VirtualBox 3.2.8), the host is OS X Snow Leopard. The problem is that the sound is very choppy. I've checked around VirtualBox and Arch forums and it seems that some others experience these problems as well yet I could not see anyone sufficiently skilled to debug this paying attention. I think there is a problem with either VirtualBox implementation of the sound card or a bug in ALSA driver for that card because I have sound running just fine in VMWare Fusion (using es1371 (?) driver), so the host system definitely is fast enough for decent sound quality. I would like to offer my help with identifying the cause of the problem and testing solutions if the need be. I've attached my alsa-info output for your reference. Please let me know if there is anything else I could try to help. I am very keen to help but I don't know how. Best regards, Lex

[alsa-devel] [PATCH] ASoC: multi-component - Drop board-n8x0.c changes
by Jarkko Nikula 17 Aug '10

17 Aug '10

These will conflict with queued changes to board-n8x0.c coming from linux-omap tree. Only side effect from this dropping is that the integrated digital microphone on Nokia N810 will stop working when ASoC multi-component is merged. As currently the N810 is not very usable in mainline, I consider this as a minor issue that can be fixed in linux-omap tree the after the multi-component is merged.

[alsa-devel] [PATCH] ASoC: Multi-component: JZ4740: QI_LB60 board fixes
by Lars-Peter Clausen 17 Aug '10

17 Aug '10

This patch contains two small fixes for the sound board driver for the qi_lb60 introduced by the multi-component patches: * Remove unnecessary includes: Those includes where only used to get the definitions for the DAI devices and are thus not needed anymore. * Fix a typo.

OK. Did you test the latest alsa-driver-snapshot? ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-sna… The multi-SPDIF support is generic for all Realtek codecs. Takashi
