Hello.

Here are the bug id's for the various issues from the ALSA bugtracking system:

On vanilla Linux 2.6.12.3 and 2.6.13-rc4 modprobe hangs in D-state when loading the snd-ad1816a module. No messages have been logged to the syslog and the system is otherwise stable. Of course the sound card is unusable.

#1300: modprobe goes into D-state when inserting snd-ad1816a

Using OSS emulation with one of the VoIP phones, playback and recording stop a few seconds after the call is started. Using the ALSA interface with kphone works, but there is a continuous clicking approximately 3 times per second. Also audio latency is poor compared to the OSS driver.

#1301: Kernel OSS emulation stops working after a few seconds when used with VoIP softphones

#1302: Clicking noise when using kphone with the ALSA AD1816A sound driver

Also the ALSA driver does not have an equivalent for the "ad1816_clockfreq" option of the OSS driver.

#1303: AD1816A sound driver has no parameter to adjust reference clock frequency

Regards
Thorsten
