Re: [Alsa-devel] trouble with dosemu and alsa oss emulation (and a fix for alsa)

Hi.
I'm having trouble with latest ALSA and oss emulation. I'm using dosemu to
play some DOS games and I've noticed that sound in DOS apps stops playing
after short time (depending on the app).
I'm regulary updating both alsa and dosemu, I suspected dosemu first, since
I had no problems whatsoever with alsa oss emulation.
It turned out that this was not dosemu problem, but alsa oss emulation problem.
I've tracked it down to a change in alsa-kernel/core/oss/pcm_oss.c.
The change is here:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/alsa/alsa-kernel/core/oss/pcm_oss.c.diff?r1=1.40r2=1.41
Please, try patch bellow.

I chose to integrate a userspace tool, so further needed steps for the us428's knobs sliders can be done in userspace until all is sorted out. see us428control usX2Yloader in the following e-mails. thanks for the patch. now i commited it to cvs tree. i put us428 stuffs into alsa-driver/usb/us428 subtree to avoid spreading over a directory. also, usx2y.h is put alsa-driver/usb/us428, too. if it's necessarily exported, we can put it to alsa-kernel/include, later. the compilation seems ok. please check the cvs tree later.

Looks like you having a Thinkpad 600E notebook.
On this notebook, CS4236 driver should be used
[Alsa-devel] Please add snd-ice1712 problem to Known bugs page
Hi, I purchased a Delta 44 for playback with my consumer grade Sony ES receiver. Installation of ALSA went smoothly, and I can hear music okay, but it sometimes clips. I believe this is because the analog signal level is set inappropriately and there's no way using Linux software for me to fix it. Here's an excerpt from the Delta 44 manual: The Delta 44 Digital Recording Interface's analog inputs and outputs are compatible with a wide variety of audio products. The Delta Control Panel software allows you to configure the signal levels of each input individually, and all outputs as a group. Signal level settings of +4/Consumer/-10 are available. Selecting the +4 radio button configures the channel(s) for use with +4dBu signal levels, compatible with most musical instruments and professional mixers. Selecting the -10 setting sets up the channel(s) for -10dBV nominal signal levels, commonly used with consumer equipment such as CD, MiniDisc, cassette tape and DAT players. The Consumer setting is preferred for semi-pro audio equipment and some consumer equipment that is too hot for the -10 setting. The Consumer setting offers approximately 6dB more headroom than does the -10 setting. Semi-pro and consumer devices signal levels vary from manufacturer-to-manufacturer and even product-to-product, so a little experimentation between Consumer and -10 settings may be required for optimal results. The screen shot of the Windows driver shows the choices for +4dBu, Consumer, and -10dbV. I was unable to find any way of setting these using Linux software, including envy24control, and don't see any mention of them in the ice1712 source code. I'm disappointed because I spent extra money on this card to get good quality playback for my music. I would not have purchased it had I known this is a problem. Please make it clear on the Known bugs page or Soundcard Matrix so no one else makes the same mistake.

[Alsa-devel] RawMIDI interface programming
i need information about obtaining the correct rawmidi interface name (such as hw:0,0,1), corresponding to the MIDI synth device, from the system; i think it could be done by reading some files under /proc/asound, but which files? thanks, Marco -- Hardware is never old.

Re: [Alsa-devel] [PATCH] Enable SPDIF input recording on ALC650 AC97 codecs. Works for PCM and AC3.

This patch enables the SPDIF input of the Realtek ALC650 chip which is an AC97 compatible chip. It also adds some data into the proc file system ac97 /proc/asound/card0/ac97#0 file so one can see if the SPDIF is locked or not. I can now record AC3 non-audio data from an Optical SPDIF socket on my Motherboard. This only works for ALC650 Rev.E or above, so I guess I should really check for that. thanks, i applied to cvs with a little modification. Takashi I have just looked at the modification. Was there a reason to remove the ac97_proc.c patches ? it's there but in an if block checking the id with ALC650.
