[alsa-devel] OSS sequencer mode and SNDCTL_SEQ_CTRLRATE
by Claudio Matsuoka 24 Sep '07

24 Sep '07

Hi, Using the OSS sequencer mode of ALSA, I noticed that a request for SNDCTL_SEQ_CTRLRATE always returns 100 regardless of the kernel HZ value. I therefore assume that the OSS sequencer mode always works at this rate, unlike real OSS which varies with the kernel HZ, is that correct?

[alsa-devel] Sound trouble with MCP61 chipset.
by Steven Young 23 Sep '07

23 Sep '07

Hi, I had sent a message a couple of weeks ago regarding a somewhat reproducible error I'm having with onboard audio for systems with the MCP61 chipset. Specifically, the left channel doesn't work, and emits a high-pitched tone whenever the audio device is open. Also, adjusting the volume disables all sound until the kernel modules for sound are all reloaded. I didn't receive any response to that message; is this the right place to ask? I have two machines, both with the MCP61 chipset, and both with the same problem. I have included the lspci -v output of one of them below. Thanks, Steve. 00:00.0 RAM memory: nVidia Corporation MCP61 Memory Controller (rev a1) Subsystem: ASUSTeK Computer Inc.

[alsa-devel] [PATCH] opti93x: conversion to use cs4231 library
by Krzysztof Helt 22 Sep '07

22 Sep '07

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> This patch converts the Opti93x driver to use the cs4231 library instead of just duplicating the code. Signed-off-by: Krzysztof Helt <krzysztof.h1(a)wp.pl> --- This patch requires the patch which adds opti93x support to the cs4231 library. This patch is just first pass to remove the code not used any more and just hook the driver into the cs4231 library. It can be improved as well as made more coding style correct. It was tested with full-duplex audio on the opti931 card.

[alsa-devel] [PATCH] cs4231-lib: add support for Opti93x codec
by Krzysztof Helt 22 Sep '07

22 Sep '07

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> This patch adds support for WSS compatible Opti93x codec to the cs4231-lib. Signed-off-by: Krzysztof Helt <krzysztof.h1(a)wp.pl> --- This allows to remove cs4231 duplicated code from the opti93x driver. It is almost half of the opti driver. The opti93x must use its own interrupt handler so it needs also the overrange function. That's why it is exported. The next patch will convert the opti93x driver to use the cs4231 library instead of its own code. The cs4231 library (and ad1848's) gets improved with Rene's and Trent's help so this should improve the opti driver as well.

[alsa-devel] Phoenix Audio Duet
by Shane Hathaway 22 Sep '07

22 Sep '07

Hello, I just bought a set of Phoenix Audio Duets for VOIP conferencing. They are USB speakerphones with good echo cancellation. They work fine with the snd_usb_audio module, with one exception: I can't control the microphone and speaker levels. ALSA exposes some controls, but they have no effect, so I have to shout to be heard. Rather than get a hoarse voice, I want to help enhance the snd_usb_audio module to correctly support the mixer controls within the Duet. I know the device actually has working mixer controls because Phoenix Audio provides a Windows-only utility for controlling the levels, and when I use that utility turn up the mic, I can be heard quite well. Unfortunately, the levels are reset when I move the device back to a Linux box. I used SnoopyPro to capture USB packets as I adjusted the levels in Windows and I think I know what to transmit to the device in order to read and change the levels. Now I just need to figure out how to translate that knowledge into kernel code. I am a capable C coder (though rusty), I don't know much about USB, and I've dabbled in kernel code before. lsusb lists the Duet (Executive) as: Bus 001 Device 011: ID 0556:0004 Asahi Kasei Microsystems Co., Ltd Both kmix and Ekiga see it as an AK4571. There is a data sheet for that chip here: http://www.datasheetcatalog.com/asahikaseimicrosystems/3/ I would guess that the AK4571 has mixer controls built in, but that Phoenix Audio (phnxaudio.com) chose not to use those controls and instead enhanced the USB interface with nonstandard mixer controls. So, where should I begin? I don't see evidence that anyone has worked on this yet. Shane

[alsa-devel] Tascam US122 on ARM [PATCH] and error :-(
by ST 21 Sep '07

21 Sep '07

Hi I managed to get the snd_usb_usx2y driver running on an Linksys NSLU2. The whole stuff is running under debian etch. Kernel Version is 2.6.18 with Debian patches. Below is a little patch to be able to enable the driver. Unfortunatly the driver gives the error: Sequence Error!(hcd_frame=7 ep=8in;wait=65539,frame=3). Most propably some urb of usb-frame 65539 is still missing. Cause could be too long delays in usb-hcd interrupt handling. Which is the output of the function usX2Y_error_sequence. This function is only called from usbusx2yaudio.c:328. Since all numbers lie just above 65535 (They are all between 65537 and 65540) is suspect that there is some wrap around error, especially because the values are anded with a 16 bit mask (0xffff). But unfortunatly i don't know to much about usb right now. Any hints to resolve this problem? The cpu runs with 266Mhz, so it could be that it would be really to slow, but i really suspect an wrap-around error. Any hints or ideas to solve this issue?

[alsa-devel] When to start the capture device?
by Sheng (Sean) Liu 21 Sep '07

21 Sep '07

Hello everyone, I am using ALSA to capture sound from a micrphone. I need to know when the capture device starts. In Paul Davis' Tutorial, he mentioned two approaches. But, I have questions on each of them. When to start the device When you open the audio interface, ALSA ensures that it is not active - no data is being moved to or from its external connectors. Presumably, at some point you want this data transfer to begin. There are several options for how to make this happen. 1. The control point here the start threshold, which defines the number of frames of space/data necessary to start the device automatically. If set to some value other than zero for playback, it is necessary to prefill the playback buffer before the device will start. If set to zero, the first data written to the device (or first attempt to read from a capture stream) will start the device. My question: what does he means on " If set to zero"? Does anyone know which parameter of which API should be set to zero? 2. You can also start the device explicitly using snd_pcm_start, but this requires buffer prefilling in the case of the playback stream. If you attempt to start the stream without doing this, you will get -EPIPE as a return code, indicating that there is no data waiting to deliver to the playback hardware buffer. My question: Is there anything to be done before calling snd_pcm_start in the case of capturing stream? If there is, what are they? Thanks in advance, Sheng
